Explosively developing extratropical cyclone oveer East Sea

Abstract

An extreme extratropical cyclone struck the northern part of Korea on May 3, 2016 causing significant damage to property on the land due to extreme winds and abnormal high waves in coastal area. The meteorological composite fields for the cyclone show a strong surface wind velocity (up to 45 m s&#8722 1) during its mature phase. This study investigated the development mechanisms of an explosive cyclone through numerical simulation and sensitivity experiments through the piecewise potential vorticity (PV) inversion method (Davis and Emanuel, 1991) using the Advanced Research version of the Weather Research and Forecasting (WRF-ARW) model.yclone show a strong surface wind velocity (up to 45 m s&#8722 1) during its mature phase.
