CHARACTERISTICS OF THE OUTFLOW LAYER OF TROPICAL CYCLONE RAPID INTENSIFICATION IN THE WESTERN NORTH PACIFIC
摘要
Abstract
Compared to the boundary layer processes,tropical cyclone (TC) outflow layer processes have drawn considerably less attention.It is suggested that tropical cyclone outflow is the link between environmental systems and the inner core.259 cases of TC rapid intensification (RI) in the Western North Pacific during 1979-2012 were selected.The TC best-track data from the International Best Track Archive for Climate Stewardship (IBTrACS),high-resolution satellite observation data (GOES-10/12 CIMSS;Digital Typhoon) and high-resolution atmospheric reanalysis data (ERA interim) were used to examine the upper-level outflow channel patterns and outflow interactions associated with TC intensification.There are five outflow patterns associated with the TC RI,which including a single equatorward outflow channel (SE),a single poleward outflow channel (SP),a double outflow channels (D),no outflow channel (N),as well as the transform outflow channels (T).Eight types of interactions between a TC and its surrounding environment are subdivided from the SE,SP and D outflow patterns.South Asia High,anticyclone of the southern hemisphere and the middle latitude upper-tropospheric trough (or TUTT) are the main systems that enhance the outflow channel.关键词
