Abstract:
Using the data of conventional observation, automatic weather station (AWS) observation, and Doppler weather radar observation, the tornado activity characteristics in the Pearl River Delta and environmental conditions are studied. The work presents the tornado synoptic model and early warning indexes. The forecasting and warning method and procedures towards the tornado events in the Pearl River Delta are built and applied to two tornado events in 2018. The results indicate that on the base of the method, the tornado warning for Nanhai District of Foshan was successfully issued 58 minutes in advance for Typhoon Ewiniar on 8 June 2018. On 17 September 2018, another tornado warning for Sanshui District of Foshan was successfully issued 37 minutes in advance for Typhoon Mangkhut. It is proved that this method is feasible.
