Rayleigh lidar investigation of sudden stratospheric warming observed over northern and southern hemisphere stations

Abstract

First observation of the Stratospheric Sudden Warming (SSW) was made by Scherhag in 1952, using radiosonde measurements over Berlin. Schoeberl (1978) provided a review on theory and observations of stratospheric warming using results reported from different places. The results were suggested that the warming is confined to the Northern Hemisphere, especially during winter over the polar region. Similarly, there is also some evidence of SSW occurrence in Southern Hemisphere and reported in many research papers. The causes for such warmings were attributed mainly due to planetary wave and /or Gravity wave propagation. There are many results reported for high latitude and very rarely for mid and low latitudes
