Study on the Forecast Index of Quantitative and Snow Depth in Yangzhou

Abstract

Based on the scope of Yangzhou, this thesis explores the causes and development mechanisms of snowfall in the Yangzhou region in recent years. Combining with the analysis of climate background when blizzards occur, this thesis discusses the relevant indicators of local snowfall forecast, such as water vapor, dynamics, wet potential vorticity and other physical characteristics, and compares and verifies them with the results of model forecasts, so as to establish a suitable quantitative judgment standard for local areas and provide reference for future forecast ideas. Meanwhile, by comprehensively analyzing multiple physical quantity indicators, extracting local snowfall forecast models, providing reference for snowfall depth forecast, and providing reference basis for public services and transportation meteorological services.
