An Easier Spring
We all get lost in our bubbles, our personal travails, indignities and daily dramas. Weather perception often trumps reality, it seems worse than it is.
This past winter was a bargain compared to last year. Early March 2014 MSP saw as much as 21 inches of snow on the ground. This year: 2 inches. A year ago 3 feet of frost was in the ground. This year: less than a foot. Snowfall of 32.1 inches is roughly half the 62.7 inches that fell last winter, to date.
Tim Elrod asks “Does a double El Nino mean an extra hot drought in the Midwest this summer?” If I had the definitive answer to that question I’d be hanging out with Sir Richard Branson. My sketchy, semi-educated, almost reliable hunch? 2015 may bring a warmer, drier bias, based on a persistent El Nino warm phase in the Pacific and an apparent southward shift to the jet stream. I fear we’ll be talking about drought much of the year. My confidence level is low – I hope I’m wrong.
Today will be a fine day (for mid-February) with a hint of spring returning by Saturday. No snow in sight; the atmosphere mild enough for rain Sunday, again next Wednesday. A few 60s are likely early next week.
Spring is coming, slowly but surely.
Perfectly Normal – For Mid February. Today will feature a fleeting temperature relapse, readings 10-15F colder than average with highs in the mid 30s. 70s are tantalizingly close. I can’t promise 70F but low 60s are possible early next week. 4 pm temperature forecast for Friday courtesy of NOAA and Ham Weather.
Hints Of Spring Next Week. Today will be chilly; temperatures stuck in the 30s, but Pacific air returns early next week with highs clipping the 60-degree mark before cooling down again late next week. The atmosphere is warm enough for rain showers, especially the middle of next week. Graphic: Weatherspark.
A Slow Northward Retreat. Long range guidance (GFS) continues to show a slow northward shift to the coldest air; more of a moderate, zonal flow by April 9. Winds at 500 mb (18,000 feet) are forecast to blow from Seattle and Vancouver, meaning highs close to average. Credit: GrADS:COLA/IGES.
Moore, Oklahoma: Tornado Magnet. The Washington Post’s Capital Weather Gang has a good summary of Wednesday’s tornado outbreak, and speculates on why the southern suburbs of Oklahoma City have been struck so often in recent years: “…Other than the fact it lies in the heart of tornado alley, there is no clear reason why Moore keeps getting hit by tornadoes. Studies have shown urban environments can sometimes enhance rain from thunderstorms downwind of cities (and Moore is just south of Oklahoma City), but little work has been done to determine if cities impact tornado formation...”
Tornado Seasons Like The Ones You’re Used To Could Be Changing, New Studies Find. Here’s the intro to a story at weather.com: “When eliminating (E)F0 tornadoes from yearly counts, which have steadily risen over the past few decades due to more extensive spotter networks, the implementation of Doppler radar, and advanced technology such as smartphones and social media, there is essentially no long-term yearly trend in the raw number of (E)F1 and stronger tornadoes. However, the number of days with at least one (E)F1+ tornado in the U.S. has fallen from an average of 150 such days in the early 1970s to around 100 days in the first decade of the 21st century, according to an October 2014 study in the journal Science...”

Snowflakes Aren’t Even Like Themselves, New 3D Images Reveal. Here’s an excerpt of an interesting article from LiveScience and Yahoo News: “You’ve heard that no two snowflakes are alike, but it gets even more complicated: The two sides of the same snowflake aren’t even alike. Now, researchers using a cutting-edge 3D camera are able to use these imperfections to update estimates of road slickness and other storm impacts, improving winter weather warnings in real time and saving lives…”
Troubled National Weather Web Sites Among Government’s Most Popular. Here’s a clip from an Andrew Freedman story at Mashable: “…Uccellini readily admitted that the NWS’ warning and forecast dissemination system “is broken.” “We are very aggressively trying to replace our dissemination system,” he told Mashable last year. “I’m not walking away or trying to hide.” The NWS has been prevented from developing its own mobile apps because of statutes that forbid it from competing with the private weather sector…”
When It Comes To Nature’s Public Enemy Number One, The Mosquito Is A Modern Monster. You’re preaching to the choir – here’s a clip from The Australian: “They are the answer to the classic quiz question: “What is the most deadly animal on earth?” By the time contestants have debated the demerits of tigers, cobras and great white sharks scores of victims of the real worst killer will have died and other people will have been infected by the diseases it spreads. The mosquito goes about its deadly business every day, moving infections around that kill hundreds of thousands of humans every year..”

Meet The Cool Beans Designed To Beat Climate Change. NPR has a story of innovation and adaption; here’s a clip: “A planet that is warming at extraordinary speed may require extraordinary new food crops. The latest great agricultural hope is beans that can thrive in temperatures that cripple most conventional beans. They’re now growing in test plots of the International Center for Tropical Agriculture, or CIAT, in Colombia. Many of these “heat-beater” beans resulted from a unique marriage, 20 years ago, of tradition and technology. The matchmaker was a Colombian scientist named Alvaro Mejia-Jimenez. But for almost two decades, his innovation sat on the shelf, unused…”

Tropics Getting Warmer: Sign of Warming Times? Discovery News has the research, which mirrors what we’re seeing in northern latitudes: fewer storms during the warm months, but the storms that do form tend to be larger with more intense rainfall: “…Tan’s group, along with NASA, published the study. Thunderstorms play a key role in tropical weather. Thought they occur just 5 percent of the time, researchers said, they account for about half of the rainfall in the tropics. “What we are seeing is more big and organized storms and fewer small and disorganized storms,” Tan said…”

Ted Cruz Compares Climate Change Activists to “Flat Earthers”. Where To Begin? Here’s an excerpt from an Op-Ed at The Washington Post: “…First, Cruz conflates the science of climate change with the politics of climate change. Scientists don’t scream, “You’re a denier.” They point to the scientific evidence that human activity is leading to climate warming — the evidence of which is overwhelming. (Here’s the international version and the U.S. version.) There is no “evidence that disproves their apocalyptical claims,” because if there were, scientists would abandon the theory. That’s how science works…”
How Should Journalists Treat Candidates Who Deny Climate Change? Here’s an excerpt from The Los Angeles Times: “…Climate change denial, at its core, is an economic position, not scientific. Reporters who take a basic “follow the money” approach soon discover that their path leads them to fossil fuel interests. The oil and gas industry was the second-largest source of campaign donations to Cruz, at $1.1 million in 2011-14, according to the Center for Responsive Politics. It’s the leading donor to Sen. James Inhofe (R-Okla.), the Senate’s top climate change denier, making $576,000 in contributions since 2009. (The second-largest donor: the utility industry, at $278,000.)...”

The Real Cost of Coal. The fundamental problem right now: the true cost of burning coal (and other fossil fuels) is not being factored into the markets. Fossil fuel companies are getting a free pass by being able to pump as much CO2 into the atmosphere as they want. Here’s a snippet of an Op-Ed at The New York Times: “…This failure by the government to collect fair value for taxpayer coal is made more troubling by the climate-change implications of burning this fossil fuel. Taxpayers are already incurring major costs in responding to the effects of global warming. Coastal infrastructure is being battered by sea rise and storm surges; forests are being devastated by climate-aided pest infestations; and studies are suggesting that temperature rises have increased the likelihood of devastating droughts in California...”
Scientist Says Florida Wasting Time Debating Climate Change. The scientist is Dr. Neil deGrasse Tyson, and here are recent comments, courtesy of HeraldTribune.com: “Renowned scientist Dr. Neil deGrasse Tyson called Gov. Rick Scott’s ban on official use of the terms “climate change” and “global warming” astonishing and disappointing, and held voters responsible for electing Scott and other like-minded politicians to office. “I thought as a nation we were better than this,” Tyson said. People like to blame politicians, he said, but the challenge is educating the electorate...” (Image: NASA).
U.S. Is Laggard Among Developed Nations In Understanding Climate Change. InsideClimate News has an interesting article; here’s an excerpt: “…Capstick and his colleagues found that during the 1980s and 1990s, there was increasing awareness and public concern about the issue around the globe. In many countries, skepticism about the scientific evidence of climate change took hold late in the following decade, and climate quickly became a partisan issue largely because of the global recession and concern that taking action would hurt economies. But while most countries have since moved away from this partisan divide, the political split over climate change has only widened in the U.S., Capstick said. This reflects fossil fuel-funded denial campaigns and the widening ideological divide between conservative and progressives in the U.S. Australia and the U.K. have similar divides…”
