February 2012 the globe's 22nd warmest; record Hawaii hailstone confirmed

February 2012 was the globe's 22nd warmest February on record, according to the National Oceanic and Atmospheric Administration's National Climatic Data Center (NCDC). Global temperatures were the 15th warmest on record according to NASA. It was the coolest February since 1994, and the coolest month, relative to average, since January 2008. The relatively cool temperatures were due, in part, to the on-going La Niña event in the Eastern Pacific, which has brought a large amount of cool water to the surface. February 2012 global land temperatures were the 37th warmest on record, and ocean temperatures were the 12th warmest on record. Global satellite-measured temperatures for the lowest 8 km of the atmosphere were colder than average, the 7th or 13th coldest in the 34-year record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH). February temperatures in the stratosphere were the coldest on record. We expect cold temperatures there due to the greenhouse effect and to destruction of ozone due to CFC pollution. Snow cover during February varied dramatically depending on which hemisphere you were in. Eurasia had its third largest snow cover extent in the 46-year period of record, while North America had its fourth lowest. As seen in Figure 1, much of North America and Siberia were much warmer than average, while Europe was considerably colder than average. Wunderground's weather historian, Christopher C. Burt, has a comprehensive post on the notable weather events of February in his February 2012 Global Weather Extremes Summary.

La Niña weakens, almost gone
A borderline weak La Niña event continues in the equatorial Pacific, where sea surface temperatures were approximately 0.5°C below average during February and the the first half of March. NOAA's Climate Prediction Center forecasts that La Niña will be gone by the end of April. The majority of the El Niño computer models predict neutral conditions for this fall, during the August - September - October peak of hurricane season, though 32% of the models predict an El Niño will develop. El Niño conditions tend to decrease Atlantic hurricane activity, by increasing wind shear over the tropical Atlantic.

February Arctic sea ice extent fifth lowest on record
Arctic sea ice extent was at its fifth lowest extent on record in February, according to the National Snow and Ice Data Center. Continuing the pattern established in January, conditions differed greatly between the Atlantic and Pacific sides of the Arctic. On the Atlantic side, especially in the Barents Sea, air temperatures were higher than average and ice extent was unusually low. February ice extent for the Barents Sea was the lowest in the satellite record, due to air temperatures that ranged from 4 - 8°C (7 - 14°F) above average at the 925 mb level (about 3000 feet above sea level). In contrast, on the Pacific side, February ice extent in the Bering Sea was the second highest in the satellite record, paired with air temperatures that were 3 to 5 degrees Celsius (5 to 9 degrees Fahrenheit) below average at the 925 mb level. Satellite sea ice records date back to 1979.

Huge hailstone sets Hawaii record
A hailstone with the diameter of roughly that of a grapefruit that hit Oahu on March 9, 2012, has been confirmed as the largest hailstone on record for the state of Hawaii, according to NOAA. The record-setting hailstone was dropped by a “supercell” thunderstorm on the windward side of Oahu. There were numerous reports of hail with diameters of 2 to 3 inches and greater. Hail the size of a penny (diameter of 3/4 inch) or quarter (diameter of one inch) has been reported in Hawaii only eight times since records began, and there is no record of hail larger than 1 inch in diameter. Hail the size of golf balls and baseballs can only form within intense thunderstorms called supercells. These supercells need warm, moist air to rise into progressively colder, drier air, as well as winds changing direction and increasing speed with increasing height off the ground. For both sets of conditions to exist at the same time in Hawaii is extremely rare, but that did occur on March 9. Conditions that day were ideal for a supercell to form, and the storm looked very much like supercell thunderstorms common in the Central U.S. during spring. Supercells can also produce tornadoes, another rarity in Hawaii. The same hail-producing supercell produced a confirmed EF-0 tornado with winds of 60-70 mph in Lanikai and Enchanted Lakes on Oahu.

What.? No one majoring in Agriculture or Anthropology.? :o



hahaha

Yeah, there are only two types in my class, math majors, and various majors in the physics family.


Its an early class too, I wish it was later, it started at 9 but it takes nearly an hour drive to get there...

I didn't really have a choice though, the school only had 2 other classrooms available due to such low demand for the class, and both of the other ones were open during times when I am at work.



What is really crazy is my professor heads the math AND the physics department! He double majored in both apparently, and decided to be a professor in both, lol.

Yeah I don't think hes unfair, hes just so darn good at what he does that its hard for him to gain perspective. We never get trick questions, and he always works out hard problems and gives us time to copy his notes and warns us that he will give us challenging problems.

But his exams are definitely harder than average, they usually are similar to the harder home work problems. We also fly through the course pretty quick.


Still though, I don't blame him, I would consider his teaching style to be higher level, not bad teaching style, he just definitely challenges his students to put above the minimum required by the class to paint it nicely :)


He seriously works the problems we work on as if its elementary algebra to him, so if I was in his shoes, I would imagine to him it feels like hes going easy on it. He has got to much more proficient at Calculus than your typical community college Calc professor. He is an absolute master at mathematics, the harder the problem is, the more it fires him up and he will solve it in no time, yet he still writes every step for us, which is nice.

I know 95 was El Nino to Neutral, however what I was stating is, that is when we got back into a warm AMO period. Two things that are now in a positive mode is the Gulf of Guinea is still showing cooler anomalies, which allows for the ITCZ or allowing the monsoon trof to materialize and shift further north, which will allow for the Sahel to get rain, and if the GoG stays cool, the shift in the monsoon trof will allow for stronger waves.

The eastern ATL has been warming slowly as the NAO has weakened and is forecast to go slightly negative, which would allow for the eastern ATL to recover somewhat...not fully, but warmer than it is currently.

Q: Are there any benefits to having a hurricane?

A: Believe it or not, yes. Hurricanes are play a very important role in preserving the heat balance that the earth maintains by transferring heat from the tropics to the poles. They also can be very helpful to areas affected by drought with their torrential rains.

I just scanned most of the tropical prediction sites and this piece of article is just about what they all are saying for this coming 2012 season:...Overall, the predictions are not dire for 2012. The season is being forecast to be relatively tame. Forecasters seem to agree mostly that there is a probability of 12 named storms and out of the 12 named storms, seven possibly will develop into hurricanes.

Well, there are a few problems wrong with those years. For one, the activity this year would be much less. Secondly, 1995 was El Nio to Neutral, 2001 was La Nia to Neutral, and 2002 became a moderate El Nio, although it is probably the best analogue out of the three. Finally, all three years had a lot of Cape Verde activity...we will not see that this season.
