我国雷暴活动对太阳耀斑爆发的短期响应

SHORT TERM RESPONSES OF THUNDERSTORM ACTIVITIES TO CHROMOSPHERIC FLARES OVER CHINA

本文研究了1971—1980年间296个2级以上耀斑爆发对我国185个气象站上空雷暴活动的中短期影响.发现雷暴对耀斑的短期响应存在明显的空间差异,在一些区域中耀斑爆发后雷暴活动明显增强,而在另一些区域中明显减弱,在这些明显响应区域中,雷暴活动在耀斑爆发前后的差异显著性通过了10^(-3)—10^(-6)的置信度检验.这些结果给太阳活动与地球短期天气相关机理的传统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 responses of thunderstorm activities to solar flares of class 2 or greater over 185 meteorological stations in China from 1971—1980 are studied. That the responses with the significance level better than 10^(-1) are quite different for different regions means that the thunderstorm activities after the flare obviously enhances in some regions and weakens in the others, gives a new challenge especially to the study of the correlation mechanisms between solar activities and short term weather, and provides a new basis of the facts for further study as well.
