Abstract

This paper is concerned with the correlation between the echo power and the wind shear observed on June 10 and 11, 1983, by the Arecibo UHF radar at the altitude of 13–22 km. Correlation values of 0.76 and 0.82 were obtained on each day between the range-corrected echo power and the square of the wind shear for the horizontal wind fields due to both the mean wind and waves with a relatively large vertical scale. The maximum echo intensity occurred at approximately 500 m higher altitude than that of the wind shear. A ratio between the range-corrected echo power and the square of the wind shear averaged in the whole altitude region was similar for observations done on 2 successive days.
