Abstract

The authors from the earlier investigations of the M-100 Soviet rocketsonde temperature and wind data for the tropical station Thumba (8.5°N, 76.9°E) identified occurrence of high-level warmings during both the winter and the summer monsoon seasons. There was good agreement between the occurrence of high-level warmings and the monsoon activity in the Indian region. The study further indicated a possible relationship between the stratospheric quasi-biennial structure and the monsoon rainfall. To test the validity of the above results for tropics, the rocketsonde temperature and wind data for Ascension Island (8.0°S, 14.4°W) and Kwajalein (8.7°N, 167.7°E) for four winter seasons (December to February of 1970–1971, 1971–1972, 1974–1975, and 1975–1976) and four summer monsoon seasons (May to September of 1971, 1972, 1975, and 1976) were studied. The above periods are the same as those of the earlier study for Thumba. Out of the above years, 1972 and 1975 were the years of contrasting monsoon activity. The results of Ascension Island and Kwajalein agreed with those of Thumba
