Abstract:

Data collest 1959 from a 32-m topometeorological tower located in a semiarid region in Southeast Washington were used to investigate 15-min vertical distributions of moist-term refractivity. Three case studies, each covering a 24-hr period, were made for different conditions. The temporal distribution of maximum and minimum values of moist-term refractivity was correlated with wind velocity, temperature changes, and rain-shower occurrence. Minimum fluctuations in the gradients of moist term and total refractivity occurred during periods in which a local drainage wind was pres ent. Maximum variations were experienced during rain-shower activity. Changes in the moist-terrm and total refractivity for the 32-m layer were as large as 52 and 61 units per 1000 ft in a 30-min period, respectively. Author
