天气发生器与SDSM两种统计降尺度技术对长江中下游地区最高温度模拟的比较研究
A Comparative Study of Weather Generator and SDSM Methods Simulation on Regional Highest Temperature of Middle and Lower Reaches of Chang Jiang River
摘要
Abstract
First, the downscaling methods are briefly introduced in this paper. Then two kinds of downscaling techniques, weather generator and SDSM, are discussed in detail. Simulation and comparison for the summer and annual highest temperature of the middle and lower reaches of Chang Jiang River from 1961 -2000 are made by dint of the two kinds of downscaling techniques. The results show that: beth two techniques have a better simulation skill on the mean and minimum regional highest temperature than the maximum one in summer and of the year;the simulating values of weather generator has a biggest deviation to the observed resutls, and weather generator performs worse in simulating annual maximum, minimum and mean highest temperature than the ones in summer; SDSM simulates the highest temperature better than weather generator beth in summer and of the year, and it will be the main tendency of downscaling techniques in the future.关键词
