Atmospheric Foul Play - Springy By Late Next Week
"You can’t see Canada across lake Erie, but you know it’s there. It’s the same with spring. You have to have faith, especially in Cleveland" mused Paul Fleischman.
Is this pattern foul or fowl? Only a duck could love this weather. Then again spring is always two steps forward - one step back. Or is it the other way around?
Weather is the pond in which we live, impacting us in a myriad of ways, beyond the obvious. Today comes word of new research showing the risk of concussion and injury in the NFL is twice as high when it's 50F than when it's a balmy 70F at the stadium. If you've ever been tackled on a subzero day that finding should resonate.
Showers linger today, spiked with wet snowflakes Thursday. A few slushy lawns can't be ruled out by Friday morning - even a few inches of sloppy snow along the North Shore.
Temperatures bottom out Saturday morning; the atmosphere warm enough for rain showers by Sunday. Models show another minor Canadian intrusion early next week, but a more springlike pattern returns by late next week. Consistent 50s and 60s within 2 weeks?
What Counties See The Most Tornado Watches? Southern Alabama sees more tornado watches (on average) than Texas and Oklahoma? Here's an excerpt of an interesting post at The Weather Channel: "...The first map below shows the number of tornado watches issued by county in the United States during the 20-year period 1993-2012. During that time, ten or more tornado watches were issued each year from parts of Kansas, Oklahoma, and north Texas to portions of Alabama, west Georgia and the Florida panhandle. Counties near the Gulf Coast typically see the most tornado watches each year. Washington County, Alabama, tops the list with 17 tornado watches annually..." (Map source: NOAA SPC).
The relationship between thermodynamics and sea ice thickness can be thought of most simply in terms of freezing degree days (FDD), which is essentially a measure of how cold it has been for how long. The cumulative FDD is simply daily degrees below freezing summed over the total number of days the temperature was below freezing.NSIDC scientist Andrew Slater has an amazing chart on his website of freezing degree days in 2016 compared to other years at 80 degrees north latitude..."

In Cold Weather, NFL Players Have a 2-Fold Greater Risk for Concussions. Medical Daily has a summary of recent research; here's an excerpt: "Researchers from St. Michael’s Hospital in Canada collected and analyzed data collected for each week over the 2012-2013 and 2013-2014 sports seasons for all 32 National Football League (NFL) teams. They found that NFL players had a two-fold greater risk of concussions and a 1.5 times higher risk for ankle injuries when they played in colder weather. According to the study, the higher rates of concussions and injuries occurred when during games played in 50 degrees Fahrenheit or colder when compared with games played in temperatures of about 70 degrees Fahrenheit and higher..."

Springtime in D.C. Means Mosquitoes - and Zika. There's a comforting thought; here's an excerpt from Foreign Policy: "...Recently, the National Center for Atmospheric Research (NCAR) published a probability map for the potential spread of Zika, based on U.S. rain and mosquito patterns. Not surprisingly, the cities at highest risk were identified as those in Florida, Louisiana, Mississippi, Georgia, and the Carolinas, where summers are hot, wet, and mosquito-dense. Using the weather-based projections, we (Research Associate Gabriella Meltzer and myself at the Council on Foreign Relations) examined recent histories of mosquito-borne disease, net budgets for insect control, and estimated per capita spending on abatement in each high-risk area..."

Which Countries Are Most At Risk of Climate Change and How Can We Help? Here's the intro to a story at IRIN: "The countries most vulnerable to climate change are among the poorest and least able to respond. How to resolve that dilemma and help these places adapt to a warming world remains among the knottiest problems facing climate financing. The good news is that identifying those most in need – step one – is now a good deal easier thanks to a global league table developed by the University of Notre Dame. The Notre Dame Global Adaptation Index (ND-GAIN) measures a country’s vulnerability in relation to its ability to cope with climate change..."

We've Been Getting These Key Details About Greenland's Melting All Wrong. It's not just surface temperature increases and carbon soot accelerating melting of ice; it's also surrounding water. The Washington Post reports; here's an excerpt: "...It’s also believed that warm ocean water can help destabilize glaciers from the bottom up, melting the ice where it’s grounded to the seafloor and eventually causing large chunks to break away. Truffer pointed out that it’s “only in the last 10-plus years that people really started realizing how much of a role melting by ocean water played.” So scientists are still getting a handle on the kinds of information we need to really understand the process. And one under-studied part of the picture is underwater topography..."
