a weekend of wavelets...

Have you ever looked at the weekend forecast and seen something like:
Wind: from NNE at 12 mph

I typically focus on temperature and sunshine versus clouds, or the possibility of rain. This morning Chris was looking up the weekend forecast and for some unknown reason I asked if it was going to be windy. He told me the forecast read that the wind was being predicted at 12 mph. I told him that I'd never investigated how a 12 mph wind might differ from a 24 mph wind or a 36 mph wind and he told me that he hadn't given it much thought either.

Then he referred to the wizard...

Chris found a website that described wind scales according to the Beaufort Wind Scale. Very interesting indeed. Our 12 mph wind was eloquently defined as follows:
Description: Gentle Breeze
Effects Land / Sea:
Leaves and small twigs move, light weight flags extend. Large wavelets, crests start to break, some whitecaps.

Just a few other delightful phrases, before it gets too windy, from the Beaufort Wind Scale:
smoke will rise vertically
water is mirror-like
leaves rustle
can feel wind on your face

small trees sway

telephone wires begin to "whistle"

Enjoy your weekend.
