中文摘要: 利用甘肃省各探空站历年的高空资料，通过计算空中水汽含量和水汽通量，对其气候特征、水汽的来源或输送进行分析。结果表明，空中水汽含量和水汽输送夏季较多，冬季较少，南部较多，北部较少；2～7月是水汽含量的增长期，8月至次年1月是递减期；输送水汽的源地主要有孟加拉湾及周边海域、南海和东海海域、青藏高原、四川盆地及周边地区；输送水汽的路径主要有中层西南路径、中低层偏南路径以及东南路径。
中文关键词: 水汽含量，水汽输送，气候特征
Abstract:Based on the radiosonde data in Gansu Province, an analysis of the climate character of the vapor content and the vapor flux in the air, and the vapor source or transportation condition is made. As the result, the vapor content and the vapor transportation in the air are more in quantity in summer but less in winter, more in south and less in north. It is the increasing periods from February to July and the decreasing period from August to January. The cradle of transporting vapor mainly contains the Bengal bay, the South China Sea and the East China Sea, the Qingzang Plateau, and Sichuan Basin. The route of transporting vapor mainly includes middle-level southwest path, southerly middle-low-level path and southeast path.
