Ozone and temperature fluctuations in the strato-mesosphere with solar activity

Abstract

The response of the stratosphere and lower mesosphere to quasi-eleven-year solar activity cycle (indicated by sunspot variations) is studied by using temperature data obtained from rockets which are mostly based on datasonde system throughout the decade 1969–1978. It is suggested that the solar trace is evident at wintertime in the strato-mesosphere over low and middle latitudes. At summertime in the lower mesosphere over high latitudes the solar trace is absent. During springtime the solar signal appears over low latitudes and diminishes to the middle and high latitudes. The reverse occurs at falltime. The observed stratospheric temperature and ozone variations during the solar activity cycle are possibly within model calculations of UV and solar particle enhancements at solar maximum.
