Today lots of thunderclouds in the Netherlands.

Looking at the lightning map for NA on any summer day would tend to indicate that the band should be open all the time! Obviously the correlation, if it exists, is somewhat more complicated. I tend to believe more in the high-speed wind shear model as these events are probably rarer, coupled with the numerous times I have heard the band open with a station in mid-sentence, not unlike a switch being suddenly turned to the "on" position! Absolutely fascinating stuff.Anonymousnoreply@blogger.com
