The Hengduan Mountains are controlled by variable atmospheric circulations,so the spatial and temporal distribution of precipitation varies greatly with the different months and seasons[10–11].The accuracy of the TRMM precipitation estimation in the Hengduan Mountains is also affected by the spatial and temporal precipitation distribution.The algorithm assumes that the same precipitation formation mechanism exists in the spatial units with more consistent spatial and temporal variations in the precipitation.Therefore,corrective models are established in the spatial units to reduce the impact of spatial and temporal variability in the precipitation for the correction model,thereby improving the accuracy of the estimation.The Hengduan Mountains are initially divided into several sub-regions with similar spatial distribution patterns for precipitation.The regression equation between the TRMM precipitation and ground measured precipitation is then established for each sub-region.Finally,the TRMM precipitation lattice values are revised based on the regression equation for each sub-region.
