Abstract: A series of monthly acoustic tests has been made in interior Alaska to obtain upper air winds and temperatures and their variations during an entire season. Results of these tests show that a temperature maximum of 22 to ...

Abstract: The results of six determinations of winds and temperatures in the 30?60-km level from acoustical studies are presented. The areas studied are: Canal Zone, January 1950; Hawaii, August 1950; Florida, October 1950; Canal ...

Abstract: An investigation of the velocities of compressional waves in the region 30 to 60 km above sea level has been conducted by means of sound-propagation tests. From an analysis of these tests, knowledge of stratosphere winds ...

Abstract: An attempt was made to determine upper-atmosphere winds and temperatures to 100 kilometers by acoustic soundings during the early part of October 1951. At the first inversion near 50 km, light and variable winds with ...
