Abstract
ABSTRACT The meteorological and environmental factors favoring development of high ambient air-temperatures are practically ubiquitous climatic characteristics of desert areas during the summer season. Data taken at the Army-maintained desert test station near Yuma, Arizona, provide some basic lower and upper limits to vertical solar and total sky radiation, ground-surface temperature, dew-point temperature, wind speed, and wind direction during occurrence of higher temperatures. However, even the more favorable combinations of the surface conditions do not provide an adequate explanation for occurrence of the higher recorded temperatures at the proving ground. 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 result. The mechanism may be the vertical exchange induced by the afternoon convection, or it may be the föhn effect brought about by the synoptic pattern.
