摘  要:
利用2010~2013年逐日08:00和20:00探空资料,统计对比分析850 hPa上空温度场,结果表明,我国青藏高原夏季是一强大热源而冬季是一冷源,春季西部温度上升与秋季西部温度下降均比东部快;东、西部温度场的这种相对变化影响大气环流,冬季与夏季的温度场结构发生逆变,同时降水天气系统的作用机制也发生较大变化。

摘  要:
Based on the daily sounding data at 08: 00 and 09: 00 during 2010-2013,taking advantage of statistical and comparative analysis,the paper concentrates on the characteristics of the temperature field at 850 hPa. The results show that,the Tibetan Plateau is a strong atmospheric heat source in summer but a cold one in winter. The temperature rising in spring and dropping in autumn of the western part are both faster than the eastern part. The relative change of the eastern and western temperature field has an effect on atmospheric circulation,the temperature structure in winter and summer inverted,at the same time the interaction mechanism of precipitation weather system also has great changes.
