When studying extreme precipitation using WRF, vertical profile lines should be selected in areas with high precipitation. This is because the purpose of the study is to understand the factors that contribute to extreme precipitation, and areas with high precipitation are likely to have the strongest signals. Additionally, selecting areas with significant differences in precipitation may not necessarily provide a clear understanding of the factors that contribute to extreme precipitation.

In the case of studying the impact of terrain and cities in Henan Province on extreme precipitation, the selection of specific longitude and latitude for the vertical profiles will depend on the research question and objectives. It is important to select areas that are representative of the region of interest and that capture the key meteorological and geographical features that are relevant to the study. In terms of orientation, the choice of northeast-southwest or northwest-southeast will again depend on the specific research question and objectives, as well as the topography and prevailing weather patterns in the region
