A SHORT NOTE ON THE INTENSIFICATION AND EXTREME RAINFALL ASSOCIATED WITH HURRICANE LANE

作者：Jeff Callaghan

摘要：Hurricanes Lane intensified in the Central Pacific with data from reconnaissance aircraft indicating it reached category 5 intensity on the Saffir-Simpson Hurricane Wind Scale while moving closer to Hawaii. The cyclone weakened as it moved closer to the Hawaiian Islands with its closest approach at 1500UTC 25 August 2018 when 175 km south southwest of Honolulu with a central pressure of 995 hPa. The impact on Hawaii was mainly record rainfall and the structure of this weather system is examined here to show how the winds turning anticyclonically with height in the lower to middle level troposphere play a crucial role in the intensification of Hurricane Lane to category 5 intensity and the generation of extreme rainfall.
