基于位涡反演的台风初值敏感性试验
NUMERICAL STUDY ON THE SENSITIVITY OF TC DEVELOPMENT TO INITIAL CONDITION
摘要
Abstract
On the basis of PV theory and PV inversion,the sensitivity of Typhoon Soulik (201 3)to initial vor-tex and background flow pattern is discussed.The significant component of initial condition and its associated dynamic process related to the TC development are specifically investigated based on piecewise PV inversion.It reveals that the wind perturbations associated with convective latent heat determine the TC motion and the eye-wall structure.This component of wind perturbation from initial vortex generates a positive vorticity anomaly and enhances the lower convergence,which is in favor of triggering convection.This portion of wind perturbation al-so benefits the organization of latent heat and further intensification of cyclonic circulation.This implies that the CISK mechanism is important to cyclogenesis.关键词
