SEARCH BLOG: CLIMATE
I have been asked what I think the absence of new records mean and I have responded somewhat along this vein:
The extreme hot and cold records represent the boundaries of our climate. The absence of new records indicates to me that the weather is remaining within those historical boundaries even though it may oscillate from the warmer to the cooler side from decade to decade. It also says that our present decade is at most no warmer than the 1930s and late 1990s... or for some reason there is much less variability that allows the calculated average to be higher.Over the past few days, I provided some data and charts regarding high and low statewide, monthly temperature records for the U.S. from 1880-2008. Yesterday, I spent the better part of the day trying to find a software program that would map that data for me. After several frustrating attempts at various software, I downloaded a trial version of Microsoft MapPoint. It is a bulked-up-on-steroids version of the mapping module that used to be part of Excel. I played around with it for about an hour and through the magic of copying and pasting was able to product the following charts.
This takes the averages of monthly high and monthly low temperatures by state to create relative "climate boundary" maps. There may be other ways of expressing these data visually and I will tinker with that for awhile.There are some apparent climate anomalies including California which is heavily influenced by the desert south and Hawaii which has Mauna Kea. Still, I think it does give a nice climate boundaries representation of the U.S.

The small bar charts represent the monthly data
and provide both level and variation changes.
Not too surprising the results. The Southwest has the greatest variability with desert influences and the Southeast the smallest variances with the ocean and gulf influences. One can see the appeal of Florida.
Obviously, Alaska and Hawaii represent unique climates.
