Reconstruction of Asian monsoon climate in the 20th century based on data rescue

将20世纪50年代以前亚洲季风国家的纸本气象资料数字化为基于计算机的气候数据集，分析了整个20世纪亚洲季风、台风活动和台风路径的长期变化。日本冬季风的减弱和缩短趋势，菲律宾夏季雨季的延迟趋势，东南亚地区降雨强度的增加趋势，台风数量的多年代际变化，以及低纬度地区台风路径的北移。

Paper based meteorological data in monsoon Asian countries prior to the 1950s have been rescued by digitizing into the computer based climatological dataset, and long-term variations of Asian monsoon, typhoon activities, and typhoon tracks during the whole 20th century have been analyzed. The weakening and shortening trend of winter monsoon in Japan, recent delayed tendency in summer rainy season onset in the Philippines, increasing trend of rainfall intensity over Southeast Asia, multi-decadal variations in the number of typhoons, and northward shift of typhoon tracks in the lower latitude region have been found.
