Document Summary
It sculpts rocks, moves leaves, blows smoke, and lifts water vapor upwards, where it can condense into clouds. Wind is with us everywhere we go, on a hot day it cools us, on a cold day it makes us shiver. Through storms and lar fair-weather systems it moves energy and matter around the globe. It transports heat, moisture, dust, insects, bacteria, and pollen form one area to another. Earth"s la(cid:374)ds(cid:272)apes are shaped (cid:271)y (cid:373)o(cid:448)i(cid:374)g (cid:449)i(cid:374)d which in tur moves water, snow, dust, etc. Circulations of all sizes exists in the atmosphere. Little whirls form inside bigger whirls, which encompass even larger whirls one huge mass of turbulent twisting eddies. For clarity, meteorologists arrange circulations according to their size. This hierarchy of motion from tiny gusts to giant storms is called the scales of motion. Eddies constitute the smallest scale of motion the microscale.
