From available data from sounding balloon ascents and sound propagation expertmentas the height-temperature curve for Central lndia from ground up to 100 Km has been constructed. It is seen that the isothermal region which is found in the lower stratosphere over middle latitude does not exist over India and that temperature steadily in increases above the tropopause. This result is in agreement with Nazarek's conclusion from V-2 rocket soundings that the isothermal region does no t exist over New Mexico in the lower stratosphere. The vertical distribution of pressure, temperature and density for levels above 10 km are discussed. Mean monthly geoetrophic west wind components have been worked out for lat. 25°1 approximetely for levels between 10 km and 20 km and their varations are discussed. By comparison of Central Indian data with Central European data, west wind components during summer have been computed up to 100 km . The comparison indicates that the summer easterlies over North India in the troposphere extend upto about 30 km with strong westerlies aloft.
