摘要

[Objective]The research aimed to analyze the relationship between vertical distribution of four automatic stations and local precipitation in Taihang Mountain of Linzhou.[Method]Using mesoscale detection and statistical data of the automatic stations in Henan,the geographical distribution of the precipitation affected by underlying surface in mountainous area of Linzhou was analyzed.[Result]Surface mesoscale wind field convergence line formed by thermal action of inhomogeneous underlying surface and mountainous terrain and upward movement played the strengthening role to the low-level jet.They affected formation and development of strong convective weather.The geographic distribution of precipitation in mountainous area was highly affected by the terrain,and rainfall,precipitation days and intensity in mountainous area were significantly greater than that in the surrounding hills region.In particular,rainfall on the windward slope significantly increased,and rainfall increased as mountain height within a certain height.[Conclusion]Hourly ground data analysis at automatic stations had very good forecast indication role in formation,development and dissipation of heavy rain in mountainous areas.
