Downscaling of daily precipitation using a stochastic weather generator
摘要
Abstract
A statistical downscaling approach,including a stochastic weather generator and a downscaling technique,is developed to transfer daily rainfall in general circulation model (GCM) grid to local area.To analyze its reasonability,an area with grid of 2.5°in latitude and 3.75° in longitude in Guangdong Province is selected and daily precipitation series of 32 years in 7 stations are used.The statistical characteristics of daily precipitation series generated by the weather generator are compared with the observation data recorded both in local and grid scale.Based on the assumption of the future changed climate precipitation series from one set of history records, verification of the downscaling technique is also made by comparing the statistical characteristics as well as monthly and amount from downscaling way with those from assumed precipitation series.关键词
