Here's an interesting tidbit, kind of related to Ronseto's post from last week (http://cr4.globalspec.com/thread/38862)
New research shows that average and peak wind speeds in the Midwestern and eastern U.S. have declined over the last 35 years. The "trend shows a 10 percent drop or more over a decade." That's sizable, and the researchers link it to climate change, although "ambiguity of the results is due to changes in wind-measuring instruments over the years."
The study "suggests that average and peak wind speeds have been noticeably slowing since 1973, especially in the Midwest and the East."
[in a bizarre meteorological aside, northern NJ had 7" of hail this afternoon]
