On the basis of climate and reanalysis data, a contribution is estimated of tropical cyclones (TCs) to the fluxes of heat, moisture, momentum, and mechanical energy of wind over the seas of Japan and Okhotsk. The estimates are obtained for two TCs that passed over these areas. It is shown that when TCs move over both seas, the heat and moisture exchange between the sea surface and the atmosphere increases approximately by a factor of 3. Also, a significant dynamic effect of tropical cyclones on the upper ocean layer is noted, so that the flux of mechanical wind energy exceeds the background monthly mean values by a factor of 10 or more. On the example for the Far East seas, a well-pronounced dependence of disturbances in the upper ocean on intensity, size, and dynamics of the cyclone is shown. 相似文献

The mesoscale structure of tropical cyclones in the northwest Pacific in 2002–2007 at different stages of evolution (from the genesis to the maximum intensity) is studied using the QuikSCAT satellite data and JRA-25 reanalysis data. It is demonstrated that the genesis of the tropical cyclone was preceded by the formation of the stable disturbance that was observed in the vorticity field on the average 47 hours before the first report. The variability is noted of the mesoscale structure of the cyclone during the process of its formation and evolution: the increase in the intensity of mesovortices, the decrease in their number as a result of the merging, the narrowing of the area occupied by them, and localization of this area near the center at the stage of maximum development. It is shown that the relationship between the mean intensity of mesovortices at the initial disturbance and the tropical cyclone intensity is close to linear and has high correlation coefficients. 相似文献
