CLIMATOLOGICAL CONDITIONS FAVORING OCCURRENCE OF HIGH TEMPERATURES AT YUMA PROVING GROUND, ARIZONA

Abstract

Meteorological observations taken by the U. S. Army Meteorological Team at the Yuma Proving Ground, Arizona, provide some basic lower and upper limits to vertical solar and total sky radiation, ground-surface temperature, dewpoint temperature, wind speed, and wind direction during occurrence of high ambient air temperatures. However, even the more favorable combinations of these surface conditions do not provide an adequate explanation for occurrence of extreme temperatures at Yuma. The apparent key is the temperature of the air layer between 850 and 650 mbs. If this layer is warm, and a mechanism exists for bringing the air down to the surface, high ambient air temperatures exist. The mechanism may be the vertical exchange induced by the afternoon convection, or it may be the fohn effect brought about by the synoptic pressure pattern.
