摘要
本文利用福建省68个台站站址所处的纬度(Ф)、海拔高度(H)、离海距(S)和地形遮档仰角(Z)等地理因子建立推算3~6月降雨量平均值(R3-5)的模式。在福建省境内,R3~6随中、H、S的增大而增大;迎风坡R3~5增大,背风坡R3~6减少,增大或减少的值与Z有关。用4个地理因子推算R3~6,其计算值与实际值偏差比用单因子、三因子推算的偏差小,效果好。
Based on the data of geographic location at 68 meteorological stations in Fujian Province,including latitude(Ф) ,elevation(H) ,distances from seaside to station(S)and angle of elevation(Z), the paper established the model of average precipitation from March to June(R3-6). The results show that R3-6increased with increasing Ф, H and S. On the upwind slope R3-6 increased, but on the lee slope R3-6 decreased;the increased or decreased amount depends on Z. The results, based on four factors, deviate from the real one less than the method using only single or three factors.
