[PEM07-P08] Influence of solar wind and ozone on the temperatures of the troposphere and stratosphere
Keywords:solar wind, ozone, tropopause, AE index, Dst index, stability of atmosphere
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.
As the analysis result, showalter stability index which is calculated from the temperature of 500hPa and 850hPa in polar regions correlates with the AE index, Especially QBO is strong the trend at the time of the west wind. This increase in high-energy particles with the solar wind, to reduce the stratospheric ozone polar, it is possible to increase the amount of solar radiation reaching the troposphere, there is a possibility that influence the stability of the atmosphere.
Thus, changes in the stratospheric ozone due to the influence of the solar wind appears to affect the climate of the troposphere.
