Insights into intensive lightning activity in the lifetime of super Typhoon Doksuri (2023)
Year: 2026
Type: dataset
Abstract: Characteristics and formation mechanisms of lightning activity during the lifetime of super Typhoon Doksuri (2023) are investigated based on observation data from the World Wide Lightning Location Network (WWLLN) and Himawari-8/9 satellite, and the ERA5 reanalysis data. It is found that lightning activity exhibits pronounced intermittent out-break behavior, and intensive lightning flashes mainly occurred in the outer rainband region approximately 200–600 km from the typhoon center. The occurrence of intensive lightning was mainly related to the development of deep convections which were characterized by high CAPE index and low cloud-top brightness temperature. In the landfall stage, intensive lightning outbreaks were probably further modulated by the orographic lifting from the underlying surface and the island thermal effects. Strong updrafts within the typhoon provided favorable conditions for the intracloud microphysical electrification processes, and the formation of intensive lightning was interpreted via the non-inductive charging mechanism and proved with the simulations of the E-WRF model. Intensive lightning in the inner-core region occurred about 0–39 hours ahead of the typhoon intensity peak, and it may serve as a potential precursor of the rapid intensification of typhoon to a certain extent. These insights into intensive lightning activity in super Typhoon Doksuri (2023) are meaningful for typhoon forecasting and disaster warning in the Western Pacific.
