More on winter 2009-10 by CRAIG JAMES   I mentioned in an earlier article that meteorological winter is the months of December, January and February. The National Climatic Data Center (NCDC) has now released their summary of this past winter for the United States. You can find the write-up online at On the map shown here, the blue colors represent colder-than-average temperatures with the tan and orange colors warmer than average. It is obvious that most of the United States had a colder-than-average winter. In fact, a few spots in southern Texas and southern Mississippi had the coldest winter on record. In the write-up you will see that NCDC states “63% of the U.S. was cooler than average.” I challenge anyone above a third-grade level to look at the map and tell me the amount of blue doesn’t cover more than 63% of the country. It certainly looks more like at least 75% of the U.S. had a cold winter. Also of note, NCDC does not rank this winter. They always state something like, “This was the third warmest winter of record,” or something like that when the weather is warm, but no mention of where this cold winter ranked. By the way, notice that this winter was called “cooler” than average, not “colder” than average. A few weeks ago I mentioned that Al Gore had stated global warming was responsible for this cold and snowy winter in the south and east. He states on his blog: “Fact: Climate change causes more frequent and severe snowstorms. Record snowstorms need two things: temperatures below freezing, and very high humidity. On a planet warmer by a few degrees on average, the Northeast U.S. will still have plenty of days below freezing; the big difference will be warmer seas producing higher levels of moisture in the air—and therefore more severe cold-season storms.” Not only is this statement at odds with the computer models, but let’s take a look and see whether the seas were actually warmer than normal and whether there has been higher levels of moisture in the air. It is pretty easy to check this out, although something tells me Mr. Gore didn’t bother to see if his theory was supported by the facts. From […]
