Dynamical Effects of Low Frequency Oscillation on Tropical Cyclogenesis over the Western North Pacific and the Physical Mechanisms
西北太平洋低频振荡对热带气旋生成的动力作用及其物理机制

This paper explores the modulation of 30-60 day low frequency oscillation (MJO) on tropical cyclogenesis over the western North Pacific (WNP) in terms of dynamics and energy conversion,using the global reanalysis data and tropical cyclones (TCs) archives obtained from Joint Typhoon Warming Center,USA. During the westerly phase in the western part of the WNP,waves in the flow convergence region are characterized by the increase in wavenumber and the decrease in wavelength,which causes the evolution from larg...
