Abstract

Abstract

In this paper,the structures of two cyclones,named as M and N,which occurred over the southern oceans in November 2004 and impacted on the navigation of Chinese research vessel Xuelong significantly are investigated by using almost all available observational data,including FNL(Final Analysis) dataissued by NCEP(National Centers for Environmental Prediction),and GOES(Geostationary Operational Environmental Satellite)-9 infrared satellite imagery.Firstly,the synoptic back ground situation was introduced.The evlutionary processes of these two cyclones are then described based upon FNL data and GOES-9 satellite imagery.Finally,the vertical structures of these two cyclones are analyzed.It is found that cyclone had distinct warm core structure with weaker baroclinicity,while cyclone N had un-obvious warm core accompanied with a distinct spiral-shaped cloud pattern at satellite imageas well as stronger baroclinicity.
