我国雷暴活动对宇宙线福布希下降的短期响应

本文研究了1971－1980年间51个大于3％的宇宙线福布希下降对我国185个气象站上空雷暴活动的短期影响.结果表明，雷暴活动对福布希下降的短期响应存在明显的空间差异．在一些区域中福布希下降后雷暴活动明显增强，而在另一些区域中明显减弱，在这些明显响应区中，雷暴活动在福布希下降前后的差异显著性分别通过了10-2－10－6置信度检验．这些响应区所在的地理位置与雷暴活动对耀斑爆发的响应区相互对应，但响应性质恰恰相反．这些结果给太阳活动与地球短期天气相关机理研究提出了新的挑战，也为进一步的研究提供了新的事实根据．

The Short-Term Response of Thunderstorm Activity to Forbush Decrease over China

The short-term response of thunderstorm activity ot Forbush decrease over 185 meteorological stations in China from 1971-1980 is studied. The fact that the response with the significance levels from 10-2 - 10-6 are quite different for different regions means that the thunderstorm activity after FOrbush decrease obviously increases in some regions and decreases in others and the space distribution of thunderstorm activity response to Forbush decrease is the same as that to solar fiares but with opposite behaviour. This fact gives a new challenge especially to the study of the correlation mechanisms between solar activity and short-term weather pattern and provides a new observational basis for further research.
