WRF Modeling: Analyzing Terrain and City Impacts on Henan Precipitation

When using WRF to study the impact of terrain and cities on extreme precipitation in Henan Province, choose a vertical profile line and a suitable height of several meters above the ground to analyze the changes in precipitation characteristics and atmospheric variables. This vertical profile line should be chosen based on the location of cities or topographic features of interest, such as mountain ranges or valleys. A suitable height for analysis would depend on the type of atmospheric variable being studied, such as precipitation rate, wind speed, or temperature. For example, for precipitation rate, a height of 2-3 meters above the ground would be appropriate to capture the effects of surface features on rainfall intensity. For temperature, a height of 10-20 meters above the ground would be more appropriate to capture the vertical structure of the atmospheric boundary layer.
