TEMPERATURE, HUMIDITY, AND WIND VARIATIONS DURING DISSIPATION OF A LOW- LEVEL JET
Abstract
The time and height variations of temperature, wind speed, and moisture content observed at the Cedar Hill tower during the dissipation of a low-level jet on the morning of 14 May 1962 are presented and discussed. Three distinct stages of significant variations occur before sunrise at the upper levels of the tower. The three stages are: 1) a period of an abrupt and simultaneous warming and drying; 2) a period of steady temperature, mixing ratio, and wind speed; and 3) a period of pronounced decreases in temperature and wind speed and a marked increase in mixing ratio that occur progressively later with increasing height. It is proposed that these variations are produced by horizontal and vertical advection and by turbulent mixing.
