| 摘 要： | 利用我国各气象站1954—1985年的地温资料,分析发现3.2m深度的地温有“突然升高”现象,其中大部分不能用地表层的变化来解释。当“地热异常型”的地温突升呈大范围(大于10~3km)群发性时,会使该区域当年降水量明显增多;当“地热异常”呈“孤点”爆发时,不会使该地降水机率增加,但当降水发生时可以增加降水量。

| Abstract: | After analysing the Chinese soil temperature data as deep to 3.2 m depth in 1954-1985, it is found that the underground temperature has a abrupt arising in some times and in some places, which can't be explained by the rising of surface ground temperature. The duration of abrupt warming is about 0.5-2 years. When the scale of "abrupt warming region" is larger than 103 km, the yearly precipitation will be abundant in the warming region. |
