Some studies about meso-scale phenomena in general circulation have been investigated. Main results are as follows. The interdiurnal variation (quasi 2-day oscillation ) of the cumulus convection over the Kanto plane in summer is found. Long-term changes in the properties of summer precipitation in the Tokyo area is also investigated. Recent stronger precipitation is found in data analysis. Further, long-term variations of the Baiu front is statistically anaysed. The delay of northward movement of the Baiu front is found.

对大气环流中的中尺度现象进行了一些研究。主要研究结果如下。发现夏季关东平面积云对流的日变化(准2天振荡)。还研究了东京地区夏季降水特征的长期变化。资料分析发现，近期降水较强。此外，对白云锋面的长期变化进行了统计分析。白云锋面北移存在滞后现象。
