Snow flies at Chicago’s O’Hare International Airport. (Flickr/Seth Anderson) With 160,000 weather-related delays each year, Chicago’s O’Hare International Airport (ORD) is vulnerable to snow, as well as to winds, rain and other flight-disrupting conditions. AccuWeather.com Senior Meteorologist Elliot Abrams points out, however, that much of Chicago’s snow is not the traditional lake effect, as it is not located on the proper side of Lake Michigan to receive the brunt of its snowfall. Abrams said that the city has received more snow than usual this season, contributing to delays and cancellations out of this major hub.

Thank Global Warming for Freezing You Right Now

without comments

Cold
Cold

Every time the weather turns cold, morons crawl out of the proverbial woodwork, and make lame jokes and snide comments about “Where’s your global warming now?” Well, the thing is, climate change is not so simple as all that, is it? The Earth’s weather patterns are complicated, and not even entirely understood. But extreme weather is certainly part of the pattern, including cold snaps. Weather is seasonal as well, which is why it is summer in Australia right now. And not a typical summer day, but extremely hot – in the neighborhood of 50ºC1

Eric Holthaus has a fairly clear explanation of why climate change leads to cold snaps:

This particularly aspect of climate change science is not yet definitive, but here’s what may be going on:

1) The Arctic rapidly warming: It’s always going to be colder at the North Pole than it is in Miami, but the difference in temperature between those two places may already be shrinking. The Arctic is quickly losing sea ice, which is being replaced by relatively warmer open ocean. Liquid water tends to trap heat more effectively than ice, which in turn discourages the future formation of ice. It’s a feedback loop that is not working in our favor, and as a result, the Arctic is warming twice as fast as the rest of the world.

2) The jet stream is slowing down: The coldest air in the Northern Hemisphere is typically trapped in the far northern Arctic by the jet stream. However, with a little help from climate change, that barrier is starting to break down. As the temperature contrast between the warmer tropics decreases, the jet stream, whichexists due to that contrast, weakens and becomes more elongated and chaotic. Think of navigating a car through slow-moving traffic: it’s a lot less straightforward to find a quick route from point A to point B.

3) As a result, extreme weather ensures: With a slower, more chaotic jet stream, there’s a much greater likelihood of weather systems getting stuck on their paths around the planet. When weather systems stagnate, they have a tendency to intensify, sometimes breaking records for heat, cold, snow, and rain in the process. Also, when increasingly elongated paths are taken by jet stream winds, it’s easier for them to pull exceptionally cold air further southwards, which is exactly what’s happening this week.

New Coil
New Coil

Saturday night our air conditioner failed. After a few sleepless nights filled with lots of tossing and turning and rearranging fans to create cross breezes, we got a new 4-ton A/C  with matching indoor cooling coil that accepts Puron aka R-410A1. Also our copper lineset between indoor and outdoor coils had to be replaced – or repaired, but easier to just replace. The furnace that the A/C is connected to is located about 6 feet from my office – where I’m sitting now – so the last few days have been disruptive.

Since the universe decided that cutting sheet metal in my ear was not enough of a distraction, our internet service went out on Tuesday, and is still wonky. We have resumed some connectivity as of last night, but we are connecting at near dialup speeds. I’m not kidding – I checked via a couple of those internet speed tests, and my desktop was reaching maximum 47kbps upload/download.  I’m old enough to remember 56kbps being a decent enough connecting speed, but that era ended long ago. These days connecting so slowly is torture. Especially when there was a spate of large system software updates, plus an Apple keynote video I wanted to watch.  

Anyway, there is apparently some problem with a pair bonded circuit. AT&T has come twice, as they provide service up to the basement of our building, and we’ve spent many hours on tech support with XO Communications.

Soon, I”ll be able to get back to my daily routine. I glanced at my email inbox, and there are over 200 emails in there waiting for me to glance at them, or godz forbid, respond to. 

On the bright side, our new air conditioner is running, and looks like just in time, per Tom Skilling’s forecast:

Record Heat Wave Grips US. But Is It Climate Change?

without comments

Spring is Here
Spring is Here

Warm, indeed. Abnormally warm in fact, and not just in Chicago

Records are not only being broken across the country, they’re being broken in unusual ways. Chicago, for example, saw temperatures above 26.6°Celsius (80°Fahrenheit) every day between March 14-18, breaking records on all five days. For context, the National Weather Service noted that Chicago typically averages only one day in the eighties each in April. And only once in 140 years of weather observations has April produced as many 80°Fahrenheit days as this March.

Speaking at a high-dollar Chicago fundraiser hosted by Oprah Winfrey as the city basked in June-like weather last week, President Barack Obama admitted to being “a little nervous” about global warming: “We’ve had a good day,” Obama said. “It’s warm every place. It gets you a little nervous about what’s happening to global temperatures. But when it’s 75 degrees in Chicago in the beginning of March it gets you thinking … ” “Something’s wrong,” Oprah interjected. “Yeah,” Obama said. “On other hand we really have enjoyed the nice weather.”

Damn You Global Climate Change

Took for Granted
Took for Granted

Following up on my whine about not enough snow this winter, and too much rain, Tom Skilling writes:

Chicago received a hefty 3.84 inches of precipitation (water content) from Thanksgiving through January 2, almost all of it falling as rain. With temperatures around 30 degrees, the typical conversion from water equivalent precipitation to snow is about 10:1, so the 3.84 inches would convert to 36-40 inches of snow.

That is about as much as Chicago receives in an average winter. In a colder environment — with temperatures in the lower 20s — the water-to-snow ratio increases to about 15:1. That would theoretically yield between 55 and 60 inches of snow.

(click here to continue reading ASK TOM WHY: With all the rain we’ve had since Thanksgiving, what would the accumulation of snow have been if the temperature was around 30 degrees? – Chicago Weather Center.)

Now, four to five feet of snow would be enough snow that I’d be whining about summer instead…

No Snow In December

without comments

Immense Activity of a Rain Puddle
Immense Activity of a Rain Puddle

It isn’t just my feeling this winter has been unusually mild, there are facts to support my contention:

Friday’s rain is just another of the meteorological oddities which have marked December 2011.  The month, now running a 7.4-degree surplus and ranked among the mildest 12 percent of all Decembers on record over the past 141 years, is also, along with cities all over the Midwest, in the midst of a snow drought here. The month, typically Chicago’s third snowiest with 8.5 inches of snow and just behind January’s 10.8 inches and February’s typical 9.1 inches, is marching toward a midnight Saturday night close with only 1.7 inches of snow to its credit. That’s an amount which is one fifth (20 percent) the so-called “normal” tally for the month and just 10 percent of last December’s 16.2-inch total.

Lakefront hits 50-degrees Thursday; O’Hare tops out way above normal at 48-degrees, marking the 18th day at or above 40 this December. Mild Pacific-origin air swept into the area Thursday, sending Wednesday’s arctic chill with its 31-degree high packing.  Readings Thursday afternoon surged 17-degrees higher, topping out at 48-degrees at O’Hare and Midway.  Northerly Island on Chicago’s lakefront managed a 50-degree high.     The reading was Chicago’s warmest in 10 days and marked the 18th time this month that temperatures have made it to 40-degrees.

(click here to continue reading Clocks tick toward December’s Saturday night close with just 8 percent of last year’s snow on the books – Chicago Weather Center.)

I’ve made a (mental) bargain with Chicago’s weather – I won’t complain about winter’s lack of sunlight, and general dreariness, if, and only if there is substantial snow for me to play in, and photograph. Despite Tom Skilling’s report of 1.7” of snow so far this winter, downtown Chicago has less than that. In fact, only once was any building dusted with a smidgen of snow, and it melted by the following day. Rain is difficult to photostroll in, at least with my current camera equipment.

Historic Rainfall in Chicago

without comments

Another Monsoon
Another Monsoon

Intuitively, we knew there was a lot of rain this year, and especially this month, and we were right:

Two passing storms overnight dumped enough rain to make this July the wettest one in the city’s history. They also knocked out power to tens of thousands of area residents and raised fears of more flooding.

The wave of storms, which spurred tornado and flood watches across the area, raised this month’s rainfall total to 9.75 inches, drowning the previous record of 9.56 inches set in July 1889.

And with more rainy weather on the way, the record is expected to keep climbing, forecasters said.

“Ten inches isn’t out of the question,” said Andrew Krein, a meteorologist with the National Weather Service.

It could be even more.

A lot of rain wasn’t needed to smash the old July record.

As of early Wednesday afternoon, 9.05 inches had fallen this month at O’Hare International Airport, the official measuring station, about half an inch less than the record 9.56 inches that fell here in July 1889, according to the weather service. The city has averaged 3.51 inches of rain in July from 1871 through last year, weather service records show.
This July is now the ninth wettest month in Chicago history. The all-time monthly rainfall record is 17.1 inches, set in August 1987.

Burning Burning and Politicians Fiddling

without comments

Tonatiuh Resplendent

Nero fiddled, I’d say Senators like Jim Inhofe are just playing their energy company-sponsored kazoo as the planet burns up.

Arizona is burning. Texas, too. New Mexico is next. If you need a grim reminder that an already arid West is burning up and blowing away, here it is. As I write this, more than 700 square miles of Arizona and more than 4,300 square miles of Texas have been swept by monster wildfires. Consider those massive columns of acrid smoke drifting eastward as a kind of smoke signal warning us that a globally warming world is not a matter of some future worst-case scenario. It’s happening right here, right now.

Air tankers have been dropping fire retardant on what is being called the Wallow fire in Arizona and firefighting crews have been mobilized from across the West, but the fire remained “zero contained” for most of last week and only 18% so early in the new week, too big to touch with mere human tools like hoses, shovels, saws, and bulldozers. Walls of flame 100 feet high rolled over the land like a tsunami from Hades. The heat from such a fire is so intense and immense that it can create small tornadoes of red embers that cannot be knocked down and smothered by water or chemicals. These are not your grandfather’s forest fires.

Because the burn area in eastern Arizona is sparsely populated, damage to property so far has been minimal compared to, say, wildfire destruction in California, where the interface of civilization and wilderness is growing ever more crowded. However, the devastation to life in the fire zone, from microbiotic communities that hold soil and crucial nutrients in place to more popular species like deer, elk, bear, fish, and birds—already hard-pressed to cope with the rapidity of climate change—will be catastrophic.

The vastness of the American West holds rainforests, deserts, and everything in between, so weather patterns and moisture vary. Nonetheless, we have been experiencing a historic drought for about a decade in significant parts of the region. As topsoil dries out, microbial dynamics change and native plants either die or move uphill toward cooler temperatures and more moisture. Wildlife that depends on the seeds, nuts, leaves, shade, and shelter follows the plants—if it can.

HIstorical Chicago Rainy Season Continues

without comments

With a Dollar In My Hand

I knew it was a moist year, the wettest since I’ve lived in these parts, and Tom Skilling concurs:

To date, 2011 has been a very wet year in Chicago and current high water levels in area rivers and streams attest to that. Since January 1, total precipitation (rain plus the water content of snow and sleet) as measured officially at O’Hare International Airport stands at 19.15 inches. That is 6.06 inches above the long-term normal of 13.09 inches and it ranks 2011 among the wettest four percent of all years in the January 1-May 31 period.

This year isn’t the wettest, but it’s close. Chicago’s precipitation records began in 1871 and four years in that 140-year data base delivered more precipitation, with 1975 (21.56 inches) being the wettest.

(click here to continue reading ASK TOM WHY: How much precipitation have we had and how does it compare to the normal? – Chicago Weather Center.)

And yet the Climate Deniers still maintain there is nothing unusual about the 21st century weather; droughts in Texas, tornadoes devastating everywhere, floods on the Mississippi, etc., this means nothing because Al Gore is fat, and flies around on a private jet.

Chicago Prepares for a Warmer Future Due To Climate Change

without comments

Meagre Results for Lost Souls

Baton Rouge? Yikes. I’ve been to Baton Rouge, and that was pretty steamy. But what is Baton Rouge going to be like?

Regardless, this Chicago initiative is pretty smart. Are other cities this far along? I assume any government run by Republicans will have their head in the sand, pretending that the earth’s climate isn’t changing, despite evidence.

The Windy City is preparing for a heat wave — a permanent one.  City planners in Chicago have been told that as temperatures rise, some plants native to the region will die out.  Climate scientists have told city planners that based on current trends, Chicago will feel more like Baton Rouge than a Northern metropolis before the end of this century.

So, Chicago is getting ready for a wetter, steamier future. Public alleyways are being repaved with materials that are permeable to water. The white oak, the state tree of Illinois, has been banned from city planting lists, and swamp oaks and sweet gum trees from the South have been given new priority. Thermal radar is being used to map the city’s hottest spots, which are then targets for pavement removal and the addition of vegetation to roofs. And air-conditioners are being considered for all 750 public schools, which until now have been heated but rarely cooled.

(click here to continue reading With Eye on Climate Change, Chicago Prepares for a Warmer Future – NYTimes.com.)

Drive Towards the Sun

and one more snippet, but you should read the whole, interesting article (free using this link).

As the region warms, Chicago is expecting more frequent and extreme storms. In the last three years, the city has had two intense storms classified as 100-year events.

So the work planned for a six-point intersection on the South Side with flooding and other issues is a prototype. The sidewalk in front of the high school on Cermak Road has been widened to include planting areas that are lower than the street surface. This not only encourages more pedestrian traffic, but also provides shade and landscaping. These will be filled with drought-resistant plants like butterfly weed and spartina grasses that sponge up excess water and help filter pollutants like de-icing salts. In some places, unabsorbed water will seep into storage tanks beneath the streets so it can be used later for watering plants or in new decorative fountains in front of the high school.

The bike lanes and parking spaces being added along the street are covered with permeable pavers, a weave of pavement that allows 80 percent of rainwater to filter through it to the ground below. Already 150 alleyways have been remade in this way.

The light-reflecting pavement is Chicago’s own mix and includes recycled tires. Rubbery additives help the asphalt expand in heat without buckling and to contract without cracking.

385 parts per million - Polapan Blue

And I know this would have been a drop in a bucket, considering, but still, would have been nice if it would have happened for reasons other than climate change:

Among the ideas rejected, Ms. Malec-McKenna said, were plans to immediately shut down local coal-powered energy plants — too much cost for too little payback.

Rain Rain Rain

without comments

Solemn and serene

It actually seems like nearly every day in April has either been rainy, or at least overcast, but I guess that’s a bit of an exaggeration. A bit. As Tom Skilling reported yesterday:

Rain-weary Chicagoans won’t find this hard to believe. April 2011 has produced 16 days of measurable rain—55 percent more than normal and the greatest number of measurably rainy April days here in the 50 years since 1961! A scan of Aprils back to 1871 indicates the opening 28 days of the month typically sees 11 measurable rains. “Measurable rain” is defined as any rainfall which reaches or exceeds 0.01-inch.

The month’s 4.56 inches of rain through Tuesday ranks as the 17th rainiest April in 140 years of records. While 124 have been drier, only 16 have been wetter.

 

Latest storm’s rain to “swipe” Chicago; heaviest totals expected east and south–but a flood watch posted for area rivers which are running near bankful

Heavy rains sweep northeastward into an area EAST of Chicago Wednesday. Lighter rains to the west will swipe the metro area from time to time with several tenths to as much as a half inch of rain at some locations. Flood watches have been hoisted for Chicago area river basins.

And today? Rain has been steady since I woke up, and doesn’t look like today will be sunny either.

Late update: didn’t realize quite how bad the weather is in the rest of the country. Puts things in perspective a little. I’ll take a few weeks of rain over massive flooding, tornados, or whatever else.

The Man With the Snow Job

without comments

Visitors on Snowy Streets

Proving once again that Illinois elected a moron for our Senator, Mark Kirk blamed Al Gore’s divorce for the lack of climate change bill in Congress. Yeah, I know, it doesn’t seem to make much sense to me either.

Gail Collins writes, in part:

Al Gore, on the phone between plane flights Wednesday, of course, pointed to global warming. “Here’s a basic fact,” he said. “There is about 4 percent more water vapor in the atmosphere today than there was in 1970.” That extra water, he said, is because of warmer oceans and warmer air, and is returning to earth as extra-heavy rain and snow.

Remind me again why we aren’t fighting global warming? It’s win-win. Even if all the hordes of scientists are wrong in believing that human beings are causing climate change, the remedies would still be good for the environment and for energy independence.

…We could blame President Obama for doing health care reform instead of global warming, but Congress is even more afraid of the energy lobby than the insurance companies. The president seems to be planning to do what he can by regulation. That prospect makes Republicans so angry that they’re introducing legislation to prohibit the Environmental Protection Agency from using its powers under the Clean Air Act to reduce greenhouse gas emissions.

Obviously, there is nothing more nefarious than having the agency in charge of protecting the environment use the clean air law to keep harmful gases out of the atmosphere.

The Senate sponsor is James Inhofe of Oklahoma, who recently claimed that the supercold winter proves that theories about global warming are “an intellectual fraud.” We could blame Senator Inhofe, but he really isn’t all that satisfactory a villain. It’d sort of be like blaming nuclear proliferation on gophers.

Another opponent of E.P.A. action, Senator Mark Kirk of Illinois, used to be aligned with the environmentalists — until he left his moderate House district to run in a Republican Senate primary and abruptly switched positions. Defending himself in a recent interview with Greenwire, Kirk claimed that there was no longer real support for a climate change bill because of “the personal and political collapse of Vice President Gore.”

In other words, environmental warrior Al Gore is responsible for the weather, as well as the pathetic wimpiness of Mark Kirk.

Potentially life-threatening blizzard

without comments

Arched

Hmm, what are the odds it snows at all? Last time the media and the NWS freaked out about a snow storm hitting the Chicagoland area, we got about an inch of snow where I live. So keep that salt handy (cum grano salis.)1

The National Weather Service has issued an unusually dire blizzard watch, calling a storm expected to arrive Tuesday afternoon over much of northern Illinois and Northwest Indiana “dangerous, multifaceted and potentially life-threatening.”

All told, forecasters expect at least a foot of snow over much of the watch area. White-out conditions are expected at times Tuesday night, with snowfall rates of at least 2 to 3 inches per hour possible with northeast winds of 25 to 40 mph and even stronger gusts.

Localized totals in excess of 18 inches are possible, especially near the lake.

Conditions are expected to deteriorate from north to south across the region Tuesday afternoon with travel becoming “virtually impossible” at times Tuesday night into early Wednesday morning, according to the weather service. Plows will be unable to keep up with the downfall.

“The last storm of this potential magnitude to hit Chicago was in Jan. 2, 1999,” said Richard Castro, a meteorologist at the weather service. That day, he said, 18.6 inches of accumulation were measured in the city.

The all-time Chicago record was set on Jan. 26 and 27, 1967, when 23 inches of snow fell on the city, Castro added.

(click here to continue reading Forecast: ‘Potentially life-threatening’ blizzard – chicagotribune.com.)

Not In My Backyard Syndrome

A major blizzard the National Weather Service is calling “life-threatening” is on its way to the Chicago area, also bringing along strong winds that could send 18-foot Lake Michigan waves onto Lake Shore Drive Tuesday night into early Wednesday.

The blizzard watch remains in effect from Tuesday afternoon through Wednesday afternoon in several counties, including Kane, DuPage, Cook, Lake, McHenry and DeKalb. The watch is also in effect for Porter, Lake, Newton, Jasper and Benton counties in Indiana, the National Weather Service said.

The snow will begin to come in from the Southwest about noon Tuesday, with the heaviest snowfall expected to hit the Chicago area in the evening into overnight, National Weather Service meteorologist Samuel Shea said.

“The heaviest snowfall will be from 9 p.m. to 5 a.m. on Wednesday and that will be a combination of snow and strong winds that will create potential hazards,” Shea said.

The National Weather Service is calling the pending blizzard life-threatening.

“You figure if you are out traveling and you do end up going off the road, having to be rescued and you aren’t prepared for the conditions, things could be life-threatening,” Shea said.

As of Monday morning, satellite images showed an 85 percent chance of at least 8 inches of snow heading into the Chicago area and a 65 to 70 percent chance of it becoming more than 12 inches, Shea said. Totals of 18 inches are possible near Lake Michigan.

“It could very easily be measured in feet,” he said.

 

(click here to continue reading ‘Life-threatening’ blizzard on its way to Chicago area – Chicago Sun-Times.)

As much of its strength, the system’s immense size sets it apart. As of Monday evening, the National Weather Service had posted winter storm warnings, watches or advisories in at least 29 states in a 2,000-mile space stretching from the Southwest to the Northeast. “A storm of this size and scope needs to be taken seriously,” said Craig Fugate, administrator of the Federal Emergency Management Agency.

The worst conditions are expected in parts of seven states where blizzard warnings were in effect Monday night. The Monday night forecast of fierce winds, strong snow and minimal visibility covered an area as far south and west as Oklahoma, as far north as Wisconsin and as far as east as Indiana. Several inches linked to the system had fallen by 7 p.m. Monday in Albuquerque, New Mexico, where a winter storm warning extended throughout the state. A similar warning was in effect as far away as Boston, where snow could start Tuesday and continue through Wednesday night.

Still, some of the biggest concerns entering Tuesday were in cities like Chicago.

“This storm could be one of the top 10 biggest snowstorms ever in the city,” said CNN meteorologist Sean Morris. According to the National Weather Service, snowstorms that drop over 15 inches of snow occur about once every 19 years in Chicago. The last time this happened was in January 1999, when 21.6 inches of snow was recorded in the city. Officials have added 120 garbage trucks with specially attached snow plows to the city’s fleet normal of 274 trucks in expectation of heavy snowfall, said Jose A. Santiago, executive director of the city’s Office of Emergency Management. Snowfall could reach a rate of two and three inches per hour with northeasterly winds of 25 mph to 40 mph, creating dangerous “white-out” conditions across the entire Chicago metropolitan area, the weather service reported.

Footnotes:
  1. translated usually as “with a grain of salt”. History from Wikipedia: The phrase comes from Pliny the Elder’s Naturalis Historia, regarding the discovery of a recipe for an antidote to a poison. In the antidote, one of the ingredients was a grain of salt. Threats involving the poison were thus to be taken “with a grain of salt” and therefore less seriously. An alternative account says that the Roman general Pompey believed he could make himself immune to poison by ingesting small amounts of various poisons, and he took this treatment with a grain of salt to help him swallow the poison. In this version, the salt is not the antidote, it was taken merely to assist in swallowing the poison. []
