Knowledge of spatial correlations of precipitation is important for the generation of grid‐based surface precipitation data sets, deployment of data collection, selection of downscaling strategies, and interpretation of paleoclimate reconstructions. Spatial correlations of daily precipitation in China were analyzed based on a daily precipitation data set from 1951 through 2014 for 2,208 stations by dividing them into 13 region...

Precipitation is an important source of streamflow and a critical parameter in hydrological studies. However, spatiotemporal variation of precipitation in the Tibetan Plateau (TP) has been poorly characterized due to the limited distribution of meteorological stations mostly in the lowlands. In this study, we set‐up rain gauges to study summer precipitation on mountain slopes in three catchments of the southern TP from 2013 to...

Two circulation index‐based methods were applied to downscale summer daily rainfall at four meteorological stations in Chongqing, China. One is a regression method ( CIM ) and the other a hybrid circulation classification plus regression method ( CPM ). Both methods used the same three circulation indices and surface specific humidity as predictors. In the first method ( CIM ), the indices and humidity were used directly as pr...
