Influence of Different Solar Drivers on the Winds in the Middle Atmosphere and on Geomagnetic Disturbances

摘要

This report results from a contract tasking Bulgarian Academy of Sciences as follows: The grantee will investigate the effects of various solar drivers on the dynamics of the stratosphere and on the geomagnetic disturbances to the earth. To accomplish this, the grantee will create a database of all registered coronal mass ejections, magnetic clouds, solar flares, and high speed solar streams; neutral wind measurements at different atmospheric levels in the period of the above events; ionospheric disturbances measured at different stations worldwide;and different geomagnetic indices. In addition, the reaction of the neutral winds, ionospheric parameters and geomagnetic disturbances will be studied for the different solar drivers. Finally, a conclusion will be made about specific effects of solar drivers on the middle atmosphere.
