cold space
...Hmmmm. :)
okay, in words an engineer or scientist can understand its the weight of the
atmosphere which determines the barometric pressure -- high pressure areas
are oft called ridges because they are a thickening of the atmosphere -- it
is this thicker atmosphere which slows the earth from reradiating the
absorbed sunlight back into space
low pressure areas are oft called troughs -- i hope the rest is obvious
<grin>
