Then we use p-III curve to fit peak-value ofsurge of all the years to get the surge of typical return periods. The result shows that theresults of fitting by ADCIRC and by historical data coincide well in lower return periods,but to higher return periods, the results of fitting by ADCIRC are significantly higher thanthat of fitting by historical data. Due to the short time, it’s not enough for the extremestorm surge events to occur, the results of higher return periods are not reliable, so wecan’t rule out the reasonability of results based on random events set. The results offitting based on random events set are accurate in lower return periods and we can alsofully estimate the surge of higher return periods based on random events set. In thesituation of lacking historical data of hundreds of years, random events set can beaccepted as a tool to compute the return period of storm surge. Consideration of globalwarming, the possibility of super typhoons’ appearance will rise, which will result inhigher surge of return periods. In order to prevent the disaster of storm surge, thegovernment needs to deepen and reinforce the coastal engineering like seawalls and embankments.展开更多

Based on the penetrationdepth and the season of occurrence, the CHCs are divided into four categoriesincluding warm-season-deep （WSD）, warm-season-shallow （WSS）, winter-shallow（WTS） and early-spring-bottom （ESB）. Statistics show the CHCs take either aneastward or a northeastward path after entering ECYSs. After moving to the seas, theintensification of CHCs is more significant in cold season than that in warm season.They all have the reduction of the friction of the underlying surface and the increase ofthe near surface winds. The area of strong winds extends and migrates from the east tothe southeast of the CHCs. A significant increase of precipitation during the warmseasons is consistent with the penetration depth of the cyclones. While a slight increaseof precipitation in cold season cyclones and scattered precipitation is observed behindthe ESB cyclones in the early stage of spring. Synthetic diagnosis analysis of the CHCsover ECYSs shows that the latent heat release plays an important role in theamplification of cyclones during the warm season. The ESB cyclones are sensitive tothe dynamic and thermal effects from the underlying surface. The vertical stretching of the positive vorticity volume is much more significant in ESB cyclones than that in othercyclones. The height of maximum upper level divergence is proportional to thepenetration depth of the cyclone for all the categories. Diabatic heating from the underlying surface is more prominent in cold season cyclones. Downward transport ofthe kinetic energy from upper level jet and the reduced friction both have positivecontributions to intensification of the CHCs. Moist Potential Vorticity （MPV） has morecontribution to the intensification of warm season cyclones, especially WSD cyclones.The combined effects from inertial stability and shear stability are beneficial to theamplification of the cyclones in cold season. The position and strength of thetemperature and moisture front from MPV2 term at 1000 hPa coincides with the areaand intensity of precipitation, which shows that the MPV2 is an effective reference forCHCs rainfall forecast.展开更多
