[PEM08-P07_PG] Influence of solar wind and ozone on the temperatures of the troposphere and stratosphere

3-min talk in an oral session

Keywords:troposphere, stratosphere, temperature, ozone, solar wind, geomagnetic activity

The correlation between global atmosphere and solar magnetic activity is evident though the cause is not clear. In this presentation, we analyze the influence that solar wind and ozone give to the global atmosphere to examine the cause on the basis of the previous observations [1].The AE and Dst index data were used to detect the influence of the solar wind on the total ozone and the air temperature change of the troposphere and stratosphere. In the analysis, the following factors were taken into account: 1)EPP-NOx effects on ozone at low latitudes may be comparable to the effects of solar UV radiation [Callis et al., 2000, 2001; Langematz et al., 2005; Rozanov et al., 2005]. 2) Since the ozone generated at low latitude is conveyed to the pole aria of the winter hemisphere, EPP-NOx has affected the ozone reduction of the pole area.Thus, changes in the stratospheric ozone due to the influence of the solar wind appears to affect the climate of the troposphere.References[1]K.Itoh,JpGU 2008-2013
