Psychology of Snow
A veritable blizzard of e-mails, texts, tweets and calls came into my office yesterday from concerned citizens. You would have thought I was tracking a cloud of radioactivity, a volcanic eruption near Willmar - or maybe a swarm of zombies showing up on Doppler.
"Is it going to be bad?" No. It's just snow.
"Why do we panic so much now for just a few inches of snow?" someone asked at a St. Paul Rotary talk yesterday. Great question. My hunch? Far more traffic on area roads. An inch of snow at the wrong time (and temperature) can wreak havoc with people's schedules. That, and a steady drumbeat of weather drama in the media. Hey, storms are good for ratings, right?
The reality: it's tough getting a huge pile of snow when there's so much mild air already in place, and soil temperatures are still relatively warm from a few days in the 40s and 50s. A fresh blast of arctic air usually precedes our most notable snowfalls, when not only the air but the ground is cold enough for the snow to stick and accumulate rapidly.
Our quick shot of slush gives way to chilled sun later today, any snow in your yard mostly-gone by Thursday. 40s return early next week before another cold frontal passage Monday and Tuesday. Cold but not exactly arctic. A zonal, west to east wind flow from the Pacific may prevent any extended bitter outbreaks looking out the next 2 weeks or so.
Saved By Warm Ground Temperatures. (Updated: 8:30 AM). Monday and much of Tuesday models consistently brought the heaviest snow bands just south/east of the Twin Cities. But after a few days of 40s and 50s ground temperatures were too warm for rapid accumulation. Zoom into the map above and you see some 2-3" amounts in Hennepin County, but most of that melted on contact. It turns out the heaviest accumulations set up just north/west of MSP, where ground temperatures were cold enough for the snow to actually stick - some 2-5" amounts as of midnight over Wright County, as much as 5-9" over far southwest Minnesota as of midnight.Click here for the latest map showing snowfall totals.

Slushy Swath. Here is what last night's slush-fest looked like from space at about 8:30 AM this morning, courtesy of NOAA.
Sloppy Wednesday For The Great Lakes. grEarth at 9 AM showed the brunt of the rain pushing into Chicago, Indianapolis and Detroit, skies clearing over the Upper Mississippi Valley.
Seasonably Chilly. Highs may hold in the upper 30s to near 40 today and Thursday, then recover into the 40s in time for the weekend. Colder, Canadian air dribbles south next week, readings below average. A few light (rain) showers are possible Friday, maybe a coating of snow up north to help with tracking for Saturday's Deer Hunting Opener. Graphic: Weatherspark.
Another Upward Blip In Temperature Third Week of November? The GFS model has been fairly consistent, showing more 40s, even a few 50s, by the third week of November. The week after next may feel more like mid-October.
Modified Zonal Flow. The map above shows 300mb jet stream winds as of Tuesday evening at 6 PM, howling from the southwest for much of America. Winds aloft are forecast to be zonal, blowing primarily from west to east, looking out the next 2 weeks, keeping any bitter air well north of the USA. Cold air will still push into the northern states from time to time, but as long as steering winds blow from the Pacific (and not the Yukon) we'll avoid tracking Arctic air.

"The White Hurricane" - How Far We've Come With Weather Technology. In 1913 how did mariners get updated storm information? They didn't. When they left port they were on their own. That's problematic when an extreme storm with 90 mph wind gusts whips up. In today's edition of Climate Matters we take a look back in time, and project forward to a continued mild bias for much of the USA east of the Rockies the next 2 weeks. Is El Nino coming back? The trends seem to suggest that may be the case by early 2014: "WeatherNationTV Chief Meteorologist Paul Douglas looks back at "The White Hurricane" that took the lives of nearly 270 mariners on the Great Lakes. Also, what do the next few weeks have in store and could we see El Niño this winter?"
Along An Arizona Highway, Dust Storms A Deadly Part Of Life. Weatherbug has the article; here's the introduction: "The intense dust that blew through a stretch of highway, killing three people and injuring others Tuesday, is nothing new for the residents of a southern Arizona town between Tucson and Phoenix. Every couple years a dense ribbon of dust -- roughly a quarter-mile high and 20 to 30 miles long -- causes a wreck along the same stretch of highway, near the town of Picacho, said Ken Waters, a warning coordination meteorologist for the National Weather Service in Phoenix. Edward Bruce Martan, 63, was born and raised in this town and said he can almost sense when a ribbon is about to hit. "You can feel it," he said. "It`s when a cool weather front comes through. You can just predict it. It`s the same place every time. Milepost 214..."
The 5 Things You Need To Know About Wildfires. Here's a clip from a story at Huffington Post: "With each passing dry season, it seems headlines about devastating wildfires are becoming increasingly commonplace. In 2012, such blazes consumed an acreage equivalent to the combined size of Massachusetts and Connecticut. This year has likewise proved to be exceptionally devastating in many regards. You've likely heard conversations about the Rim Fire -- California's fourth-largest wildfire ever, burning a total of 260,000 acres -- or the Yarnell Fire, a tragedy that claimed the lives of 19 firefighters in Arizona. After hearing about these events time and time again, one might develop questions that most articles on the topic fail to address. Why do wildfires continue year after year? Can't we do something to better manage fires?" (Image above: Capital Weather Gang).
Death By Lightning A Danger In Developing Countries. It's an ongoing danger here too, but we have technologies and warning systems (and mass media) that many countries simply don't have access to. National Geographic has the report; here's a clip: "Developing countries have long lists of problems—illiteracy, disease, hunger, corruption. There's one more problem that has gotten less attention, until recently: lightning strikes, which cause a disproportionately high number of deaths in developing countries. Thanks to years of public education campaigns, most Americans know that "when thunder roars, go indoors." But that basic guideline isn't as well known in many developing countries, which consistently see hundreds or even thousands of deaths and injuries per year from lightning strikes. Experts point to lack of education, but a number of doctors and meteorologists from around the world are trying to change that..."

To Stave Off Decline, Churches Attract New Members WIth Beer. It gives communion a whole new meaning. Here's a clip of an NPR story that made me do a double-take: "With mainline religious congregations dwindling across America, a scattering of churches is trying to attract new members by creating a different sort of Christian community. They are gathering around craft beer. Some church groups are brewing it themselves, while others are bring the Holy Mysteries to a taproom. The result is not sloshed congregants; rather, it's an exploratory approach to do church differently..."

Thorium-Fueled Automobile Engine Needs Refueling Once A Century. Industry Tap has the remarkable story - here's the introduction: "There are now over one billion cars traveling roads around the world directly and indirectly costing trillions of dollars in material resources, time and noxious emissions. Imagine all these cars running cleanly for 100 years on just 8 grams of fuel each. Laser Power Systems (LPS) from Connecticut, USA, is developing a new method of automotive propulsion with one of the most dense materials known in nature: thorium. Because thorium is so dense it has the potential to produce tremendous amounts of heat. The company has been experimenting with small bits of thorium, creating a laser that heats water, produces steam and powers a mini turbine..."

"Enders Game" And Maneuver Warfare. With the movie about to come out I found this concerpt intriguing; here's the intro to a story at medium.com: "In the mid-1980s there arose a new theory of warfare. The idea is to avoid large force-on-force attacks, use speed instead of firepower and strike at the enemy’s vulnerabilities. Proponents describe it as fighting smart. You attack the enemy’s thinking, forcing on him an unending chain of hard choices. Still practiced today, it’s called “maneuver warfare.” At the same time the new concept was gaining popularity, an award-winning military science fiction novel was released. Orson Scott Card’s Ender’s Game is now a sci-fi classic..."

The Storm Of The Century That Comes Year After Year. No kidding. The PBS Newshour has the story (and video); here's a clip: "Klaus Jacob, a special research scientist with the Lamont-Doherty Earth Observatory, discusses the possible link between Hurricane Sandy, climate change and a move toward more frequent and disastrous weather events. Plus, why the 100-year-storm will become the two-year storm by the end of the century. For more, watch Miles O'Brien's reports on preparing for the next superstorm. This series was created in partnership with NOVA and derived from Megastorm Aftermath..."
The Subterranean War On Science. Here's an excerpt from an eyebrow-raising article at The Association for Psychological Science: "...This conspiratorial element provides a breeding ground for the personal and professional attacks on scientists that seemingly inevitably accompany science denial. The present authors have all been subject to such attacks, whose similarity is notable because the authors’ research spans a broad range of topics and disciplines: The first author has investigated the psychological variables underlying the acceptance or rejection of scientific findings; the second author is a paleoclimatologist who has shown that current global temperatures are likely unprecedented during the last 1,000 years or more; the third and fourth authors are public-health researchers who have investigated the attitudes of teenagers and young adults towards smoking and evaluated a range of tobacco control interventions; and the fifth author has established that human memory is not only fallible but subject to very large and systematic distortions..."
Researcher Helps Sow Climate Change Doubt. The Boston Globe has the story - here's a clip: "...Outside the Beltway, the science is largely settled. Yet in the capital, government response to one of the major environmental and economic challenges facing the planet is mired in an endless cycle of conflicting claims and partisan finger-pointing. The work of Soon, and a handful of like-minded scientists, is seen by critics in Congress and elsewhere as a case study in how this deadlock has been engineered by energy companies and antiregulation conservatives. “They are merchants of doubt, not factual information,’’ said Senator Sheldon Whitehouse, a Rhode Island Democrat who delivers a Senate speech every week demanding stronger air-quality standards. “Their strategy isn’t to convince people that the scientists are wrong. Their strategy is simply to raise the specter that there is enough doubt that . . . you should just move onto the next issue until this gets sorted out,’’ he said. “It gives credibility to a crank point of view....’’

Adapting To Climate Change Does Not Mean Accepting It. Here's a clip from an entry at Huffington Post: "...My view is that the technical breakthroughs needed for this transformation will come. I am counting on human ingenuity coupled with a growing cultural awareness of the need for clean, renewable energy. As early 20th century New Yorkers stepped through the manure in lower Manhattan, they knew that the era of horse-based transportation had reached its limit. Horses worked well in small towns, but created problems in larger cities. We know that a planet with over seven billion people cannot fuel its economy the same way it did when it was as a planet of one or two billion people. We also need to remember that adapting to climate change does not mean that we accept it. We still need to eliminate global warming by reducing the production of greenhouse gases."
Facing The Change: Personal Encounters With Global Warming. How do you communicate the science (and implications) without people becoming hopelessly depressed, agitated and unwilling to engage? Great question. Here's an excerpt focused on a book that is attempting to dive into the psychological impact of climate change, how it's impacting us emotionally: "Facing the Change: Personal Encounters with Global Warming is a new kind of book about climate change. Instead of experts talking at us, this innovative literary collection shares the voices of fellow citizens struggling to make sense of the concrete changes taking place in our world today. Instead of scientific facts and predictions, this book offers personal essays, poems, and short stories expressing what's going on in people's lives, hearts, and dreams. Instead of leaving readers guilty and disempowered, this book will help us all to begin to work through the full range of emotions - confusion, fear, sorrow, anger, and realistic hope - that we must face in confronting the crisis..."
Power Plants Try Burning Wood With Coal To Cut Carbon Emissions. Here's a clip from an interesting story at The New York Times: "Even as the Environmental Protection Agency considers requiring existing coal-fired power plants to cut their carbon dioxide output, some utilities have started to use a decidedly low-tech additive that accomplishes that goal: wood. Ranging in size from sawdust to chunks as big as soup cans, waste wood from paper mills, furniture factories and logging operations has been used with varying levels of success. Minnesota Power, which once generated almost all of its power from coal and is now trying to convert to one-third renewables and one-third natural gas, found that co-firing with wood was a quick way to move an old plant partly to the renewable category..."
Will Climate Change Imperil Your Cup Of Starbucks? Oh no, not the coffee. Take anything but please leave me a few feeble coffee beans to spend my "mature years". We'll see - here's an excerpt from an entry at National Geographic: "...To the relief and potential horror of caffeine addicts everywhere, Feeley said, “To see species move upslope, that means they are responding to climate change. So that’s a good thing. Because if they don’t respond, they are almost certainly doomed to extinction.” So, could coffee become an imperiled species, threatened by the steady march of climate change? It’s too soon to tell, but in remembering that jungle conversation I had in southern Peru last summer, I found some clues in Justin Gillis’ page-one story in The New York Times on Nov. 2 under the headline: “Climate Change Seen Posing Risk To Food Supplies...”
Shell Announces Plans To Resume Arctic Drilling In 2014. Here's the intro to a story at oilprices.com: "After a disastrous campaign in 2012, which forced the company to abandon all plans for this year, Royal Dutch Shell has announced that it will return to the Arctic waters in 2014 to begin exploring for oil again, but on a much smaller scale. One of the main differences this time will be the abandonment of the Kulluk conical drilling rig that ran aground last time as Shell tried to toe it back to Port near the end of the 2012 drilling season. As a replacement Shell has leased out the Polar Pioneer, a semi-submersible drilling rig owned by Transocean. The Kulluk may well be put back into operation at some other point in the future, but only if it is deemed cost effective to repair the damaged unit..."

Ten Days: How We Imagine Climate Change. The role of aerosols is coming under increasing scrutiny. Some of that air pollution may actually be preventing an even sharper spike in temperatures, worldwide. Here's a clip from a story at Australia's The Conversation: "...But here’s the twist. If all emissions were to stop tomorrow, so would the output of those human-made aerosols reflecting radiation back into space. These aerosols have a residence time in the atmosphere of just ten days, meaning that after just ten days it would be like increasing CO2 emissions by 50%. It kind of makes reducing CO2 emissions to 5% off 2000 levels by 2020 seem rather pathetic. Ten days, a time-horizon that people in the city should be able to relate to. If this were to happen, the likelihood of the positive feedbacks that are triggered by warming, such as more abundant water vapour, natural albedo loss (like melting ice an glaciers), extensive firestorms, and methane pulses, would be greatly enhanced..."
