Radiative Effects on Kinetic and Potential Energy Budgets Associated with Rapid Intensification of Typhoon Mujigae
This study investigated radiative effects on kinetic and potential energy budgets associated with the rapid intensification of typhoon Mujigae in 2015 by conducting sensitivity experiments using Weather Research and Forecasting(WRF)model simulations.The authors found that the radiations have a significant effect on the symmetric rotational kinetic energy and symmetric potential energy of typhoon.The infrared longwave radiation mainly enhances the symmetric rotational kinetic energy,the shortwave radiation being the main contributor to the symmetric potential energy.The comparison between sensitivity experiments excluding radiative effects and retaining solar shortwave radiative effects reveals that the inclusion of infrared longwave radiative effects destabilizes the moist atmosphere and augments the conversion from symmetric potential energy to symmetric divergent kinetic energy.This further enhances symmetric rotational kinetic energy through the strengthened conversion from symmetric divergent kinetic energy to symmetric rotational kinetic energy.
