A Completed Synoptic Model on 200hPa Disturbance Detection for imminent extreme Rainstorm Occurrence in the Coastal Subtropical Region

by applying subjective identification techniques on Streamline Chart at the start of Rainfall recorded in 1966-2012 at Hong Kong, with verification over an outside sample dataset in the 2013-2021 period Charles Luk Highlights: 22 January 2025- the synoptic model’s final work is to focus on stormy weather-borne synoptic features anticyclones rather than behavior types:Continue reading “A Completed Synoptic Model on 200hPa Disturbance Detection for imminent extreme Rainstorm Occurrence in the Coastal Subtropical Region”
