| 摘 要： | 将“地气图”方法引入年度降水的定性预测中,在分析了1955－1996年共42a的气修资料及地球自转速度的变化与同期地热涡族轴线走向之间的关系后,发现地热族轴线与我国东部雨带的走向基本一致,且多（少）雨带轴线与地热（冷）涡族轴线基本相合,即轴线呈南北向时,雨带亦呈南北向,反之亦然。在地球自转的减慢年,雨带往往呈南北向。

| Abstract: | A new method, "Diqi" map (or earth-atmospheric map), is used in annual precipitation with qualitative prediction. The relations between the variation of climate data, the earth rotation speed and the axes direction of geothermal vortex cluster are analyzed during 1955\_1996. The result shows that the axes direction and wet-belts in East China are similar, namely, wet(dry)-belt and axes of geothermal(cold) vortex are almost coincident. As axis is north-south direction, wet-belt is north-south, vice versa. Rain-belt is often south-north in the slow year of earch rotation. |
