Dr. Jeff Masters' WunderBlog |
Dear Readers,
Dr. Jeff Masters' blog entries below show the increasingly powerful effects of having more and more water vapor in the atmosphere due to higher and higher atmospheric temperatures. All over the world, we are having record-breaking precipition events. Note also that these events are often accompanied by incredibly strong winds, even hurricane force winds of over 100 mph, as is the case with the cyclone hitting the west coast of Europe right now. Sorry that the formatting is sloppy on this post, but you can click on the various links to read the full posts he has written.

 | Heavy snow, rain, and flooding for the Northeast U.S. |  |
 |  |
| by Jeff Masters, 3:21 PM GMT on February 25, 2010 |
The winter of 2009-2010 continues its relentless onslaught over the U.S. today, as a powerful low pressure system intensifying along the East Coast brings heavy snow, flooding rains, and high winds to New England and the Mid-Atlantic. The storm has already dropped more than two feet of snow over Eastern New York near Albany, and surrounding regions of Western Massachusetts and Southern Vermont. These regions are now seeing rain mixed in with the snow, which will limit further accumulations to 1-3 inches. Farther east, flooding is a concern for most of Connecticut, Massachusetts, Rhode Island, southern New Hampshire, and portions of western Maine, where heavy rainfall of 1-3 inches on top of a snow pack with a high water content has created runoff that has already swollen many rivers to flood stage. Heavy snow is the main concern over southeast New York, northern New Jersey, and northeast Pennsylvania. The unusually slow-moving storm is expected to drop snow amounts of up to 18" in the Pocono Mountains of northeast Pennsylvania, and in northern New Jersey. New York City, whose 30.5" of snow so far this winter is 13" above average for this date, could get up to a foot of wet, heavy snow. Philadelphia's 73" of snow for the season will get an 8-12" boost from the storm, taking their record snowiest winter even further into record territory. Wind gusts of 30-40 mph in combination with the very wet, heavy snow will make power outages a problem over much of the region.

Update on this Saturday's major winter storm in Europe
Computer forecast models continue to forecast the development of a powerful winter storm that will rapidly intensify Saturday morning into a meteorological "bomb" that will bring high winds and flooding rains to Portugal, northern Spain, and possibly France. However, today's model runs are less aggressive in deepening the storm, and no longer call for the storm to be as intense as last year's Winter Storm Klaus. Klaus, which hit northern Spain and southwest France, January 23-25, was Earth's most costly natural disaster of 2009, causing $5.1 billion in damage and killing 26. Klaus peaked in intensity at 967 mb, and brought wind gusts of 120 mph (193 km/hr) to Formiguères, France; 125 mph (200 km/hr) to Portbou, Spain; and 134 mph (216 km/hr) to Port d'Envalira, Andorra. Last night's 00Z (7 p.m. EST) run of the ECMWF model and GFS model called for Saturday's storm to have 974-976 mb central pressure. Saturday's storm still has the potential to be plenty damaging, as winds of tropical storm force with gusts to hurricane force should affect a large swath of Portugal and northern Spain.
Figure 2. Forecast from the 1 a.m. EST 2/25/10 run of the GFS model for 18 GMT Saturday for surface winds. The GFS is predicting that Saturday's storm will peak in intensity at this time with a pressure of 974 mb. Sustained winds just below hurricane force of 60-75 mph (green colors) are expected offshore from Portugal. Image was generated using our wundermap for Spain with the "model" layer turned on.

| Europe braces for destructive weekend winter storm | |
| |
| by Jeff Masters, 3:05 PM GMT on February 24, 2010 |
A large but disorganized extratropical storm located over the middle-Atlantic Ocean is expected to move rapidly eastwards towards Spain over the next two days. As the storm approaches Spain on Friday, it is expected to tap into a cold polar airmass to its north and rapidly intensify into a meteorological "bomb"--a mighty winter cyclone with hurricane force winds. Though sea surface temperatures off the coast of Spain are about 1 °C below average, the waters of 12 - ...

| Russia's Pole of Cold hits -70 °F: Europe's 2nd coldest reading of all-time | |
| |
| by Jeff Masters, 4:48 PM GMT on February 22, 2010 |
The notorious Russian winter, bane of the armies of Napoleon and Hitler, has been in classic form during the winter of 2010 . Brutal cold has been the rule this winter in the European portion of Russia, and at 9 a.m. local time on Friday, February 19, the town of Hoseda-Hard, Russia hit a remarkable -70 °F (-56.4 °C) -- the second coldest temperature ever measured in Europe. Hoseda-Hard is located in extreme northeastern Europe, 90 miles (145 km) south of the Arctic Ocea...

| January 2010: extremes and monthly summary | |
| |
| by Jeff Masters, 2:33 PM GMT on February 19, 2010 |
The globe recorded its fourth warmest January since record keeping began in 1880, according to NOAA's National Climatic Data Center. NASA's Goddard Institute for Space Studies rated January 2010 as the 2nd warmest January on record, behind January 2007. January 2010 global ocean temperatures were the 2nd warmest on record, next to 1998. Land temperatures in the Southern Hemisphere were the warmest on record, but in the Northern Hemisphere, they were the 18th warmest...

| Warmest January on record for the lower atmosphere | |
| |
| by Jeff Masters, 2:37 PM GMT on February 17, 2010 |
Earth's lower atmosphere recorded its warmest January on record last month, according to data from both the University of Alabama, Hunstville (UAH) and Remote Sensing Systems (Figure 1). The satellite measurements used to take the global temperature of the lower atmosphere began in December 1978, using the Microwave Sounding Unit (MSU) on polar-orbiting satellites. The January 2010 temperature anomaly was an impressive 0.72 °C above the 1979-1998 average, easily b...
