以甘肃天水地区实测资料为基础,应用最小二乘法原理拟合出该地区气温与降水量之间的函数关系式,其相关系数约为0.96,为以后该地区气温的预测提供理论基础。
There are much close relationship between the level of temperature and precipitation .The article is based on the measured data of Tianshui area , using the principle of the least square meth-od to fit out their function relation.Their correlation coefficient is approximately 0.96.It provides theoretical basis to temperature prediction of the area.
