1.Geostationary Meteorological Satellite Image Processing Systems(1) The distribution of atmospheric pressure connected with the typhoon has been compared from 1990 to 1994. The typhoons landing in or approaching to Japan recurve at 120-135 degrees of east longitude and 20-30 degrees of north latitude after going up north from the latitude 20 N.(2) The heavy rainfall in July 1995 has been discussed with the barometric distribution and the infrared spectra band image. Hereafter, the advancement of geostationary meteorological satellite image processing will be desired to establish the electricpower control method included the lightning and typhoons.2.Research Results on the Lightning Parameters(1) The lightning current waveforms have been obtained in 1994 and 1995 winter. Especially, in 1994, both of the lightning current and voltage waveforms between the arrster terminals could be recorded with the portable digital systems for lightning current measurement. In 1995, the lightning current could be caught till 48.5 ms with using an advanced digital system for lightning measurement.(2) A new lightning survey system has been developed to obtain the lightning spectrum easily. Actually this system could take a photograph the lightning in winter.(3) The extra-fast current transition recognized during the main stroke of lightning discharge in winter would result from the residual inductance of the shunt resistance.(4) The distributed lightning current waveforms have been discussed with comparing with the many cases.

1.（1）对1990 ~ 1994年台风前后的气压分布进行了对比分析。登陆或接近日本的台风从北纬20度北上后，在东经120-135度、北纬20-30度附近转向。(2)利用气压分布和红外光谱图像对1995年7月的暴雨过程进行了分析。今后，还需要利用静止气象卫星图像处理技术的进步，建立包括雷电和台风在内的电力控制方法。2.雷电参数的研究结果（1）获得了1994年和1995年冬季的雷电流波形。特别是在1994年，便携式雷电流测量数字系统可以同时记录雷电流和避雷器端子间的电压波形。1995年，采用先进的数字化雷电测量系统，可捕捉到48.5ms的雷电流。(2)为了方便地获得闪电频谱，研制了一种新的闪电观测系统。实际上，该系统可以在冬季拍摄闪电。(3)在冬季雷电主闪过程中，电流的超快速过渡是由并联电阻的剩余电感引起的。(4)并对分布雷电流波形进行了讨论，与多种情况进行了比较。
