摘要
在观测资料的基础上,利用GIS技术,结合DEM引入天文辐射和高程,研究了重庆地区的多年月平均气温空间分布。并采用独立于观测站外的气象哨的多年月平均观测资料进行了验证。结果表明:天文辐射和高程的气温分布模拟,能够较好地反映地形遮蔽对气温分布的影响。天文辐射的引入较好地把地形对气温要素的影响进行了量化,是对气象要素空间分布研究的一次有益尝试,对山区气象要素空间分布的研究有一定的借鉴作用。
The article, based on the observation data of stations, with the DEM and sky radiation, simulated the distribution of monthly mean air temperature of Chongqing area, and verified result by the disparate data of meteorological posts. It is showed that the model based on the DEM and sky radiation can be good to simulate the landform influence to the air temperature. It is in fact that sky radiation＇ s introduce into is a way to quantitative researches of the landform influence to the air temperature. It is a beneficial test to promote the researches on the distribution of mountains meteorological factors.
