RELATIONSHIP BETWEEN THE SOLAR ACTIVITIES AND THE THUNDERSTORM ACTIVITIES, THE ATMOSPHERIC ELECTRIC FIELD AT GROUND IN PARTIAL REGION IN CHINA

The solar disturbances might modulate weather activity has been postulated for over 100 years, but none of the physical mechanisms advanced to explain solar control of weather and have been generally accepted.Most consider processes which depend directly or indirectly on changes in solar heating. But solar influence on the Earth's atmosphere is that the solar constant variation is very small-within the 1%, so that variation of energy is very small(1). Since 1970s, many scientists indicate that solar activity can modulate thunderstorm activity and atmospheric electricity (2-7). This atmospheric electrical mechanism requires no solar energy to change the state of the Earths electric field and stratospheric conductivity, while offering the possibility of releasing and redistributing large amounts of energy already present in the troposphere.Therefore, this mechanism bypasses the difficulties inherent with heating mechanism. In this paper, the analysis of the relationship between solar flare and thunderstorm activities, atmospheric electric field at ground has been given using superposition epoch method for a full cycle of sun spot activies during 1976 to 1985.
