Several case studies of radar sea clutter are presented which show that backscatter is received from ranges much beyond the predicted radar horizon. No definite explanation for this has been found but it is believed to be primarily due to over-the-horizon scatter propagation. It is proposed to restrict the sea clutter data analysis to about 25 nautical miles range from the radars studied in order to reduce the effects of ...
Comparison of echo motions with winds aloft for a case study of 1800Z, 25 August 1961 is presented. Particular reference is made to the translational motion of precipitation echoes in the tropics, as determined by tracking selected small echoes and cells. These echo motions agree best with the 3-23,000-ft mean-layer wind, with both the 3-10,000-ft mean-layer wind and the 10,000-ft wind as next best. Preliminary results of an echo-height study ...
The synoptic situation and an analysis of the cloud cover as seen by Tiros III satellite is presented for a case study of 1800Z, 26 August 1961. Particular reference is made to the translational motion of precipitation echoes in the tropics, as determined by tracking selected small echoes and cells. Comparisons of these motions are made with winds aloft. The space smoothed translational motion of precipitation echoes in this case ...
