The Effect of Tropical Cyclone Asymmetric Thermodynamic Structure on Its Unusual Motion
台风异常运动及其外区热力不稳定非对称结构的影响效应

The tropical cyclone (TC) asymmetric thermodynamic structure of unstable stratification in TC outer region and its effect on tropical cyclone unusual motion have been investigated. Studies show that the tropical cyclone asymmetric feature exists not only in its dynamic structure but also in its three dimensional thermodynamic structure which includes temperture and humidity unstable stratification and their intensities. Difference in the asymmetirc thermodynamic structure in the outer region of a tropical cyclone can cause different tropical cyclone motion, even lead to phenomena such as the meandering, looping and recurving of tropical cyclones.
