Article
Using the upper tropospheric and stratospheric temperatures and total ozone amount data obtained from the TIROS-N satellite over the Indian region during the period May to July 1979 subdivided into six different phases of the monsoon, possible interactions between the 400-1mb atmospheric region and the summer monsoon have been examined in this pape...
Article
Using M-100 meteorological rocketsonde data collected over Thumba Equatorial Rocket Launching Station (8°32′N, 76°52′E), Trivandrum, India for the period January to May 1972, a sudden mesospheric warming followed by an almost equal cooling has been detected over this region on 1st March 1972. The Thumba equatorial mesospheric temperature showed an...
Article
An investigation of the atmospheric wind structure over Antarctica from surface upto about 80km is made using data from about 52 successful M-100 meteorological rocket soundings at Molodezhnaya, Antarctica where the author worked during 1971-73. The Antarctic summer was found to be characterised by light easterly winds which increased in strength w...
Article
Seasonal wind variations over Antarctica in an altitude region from surface up to about 80 km are studied using data from 52 successful M-100 meteorological rocket soundings at Molodezhnaya, Antarctica where the author worked during 1971-73. It is found that the South Polar summer was characterised by light easterly winds increasing in strength wit...
Article
Upper-atmospheric wind and thermal structures in Antarctica have been discussed earlier. The present study is an extension of that work and gives a complete picture of the atmospheric temperature exploration from the surface up to an altitude of about 80 km, with particular emphasis on seasonal temperature variations, by means of meteorological roc...
Article
Average vertical profiles of zonal and meridional components of winds, and of temperatures as obtained from M-100 meteorological rocket soundings conducted at Molodezhnaya, Antarctica in January-February 1972 (southern summer) are compared with those of the corresponding ascents from Thumba, South India. The actual results are also compared with th...
Article
THE mesospheric wind results derived for atmospheric altitudes between 50 and 90 km from meteorological rocket flights carried out at Molodezhnaya station (67° 40' S, 45° 51' E) in Antarctica have been discussed in ref, 1. The rapid shifts in both zonal and meridional components of the winds during May to July indicated a sudden `explosive' change...
Article
UNDER a joint Indo-Soviet agreement I was the first Indian scientist to winter in Antarctica during the 17th Soviet Antarctic Expedition, 1971-73. In particular, I participated in the meteorological rocket soundings of the upper atmosphere carried out at Molodezhnaya, a station located at 67° 40'S, 45° 51'E at a height of 42 m above mean sealevel i...

... Some of the upper atmospheric wind and temperature results from these soundings have been discussed earlier (Sehra 1974(Sehra , 1975(Sehra , 1976a(Sehra , 1976b and also compared with the corresponding equatorial results (Sehra 1976c(Sehra , 1976d. In the present investigation, the emphasis is on the tropospheric and stratospheric circulation over Antarctica, and the study presents a detailed structure of the high latitude winds of the Southern Hemisphere. ...
