Impacts of the Mountain-Plains Solenoid and Cold pool Dynamics on the diurnal Variation of warm-season Precipitation over Northern China

摘要

1 Introduction The diurnal variation of precipitation is often induced by differential diabatic heating between regions with different surface topography.The terrain over Northern China decreases from northwest to southeast in a two-step pattern with the Yanshan-Taihangshan Mountain ranges along the eastern peripheries of the Loess-Mongolian Plateaus and the adjacent North China Plains (Fig.1 a).He and Zhang (2010,hereafter referred to as HZ10) explored the diurnal variations of warm-season precipitation over Northern China using the CMORPH dataset and the NCEP GFS analysis.
