A Nomogram method for predicting typhoon surges is introduced in this paper. Based on the results obtained through numerical computation, in which 576 typhoons were taken into account, the Nomograms were plotted by using a revised method proposed by Chen and Qin. Having informed the parameters about the approaching typhoon the forecasters using the Nomograms and their own experiences can predict the peak surge, the time when the peak surge occurs and the time variation of the surge, which is caused by typhoon along the coasts of Zhejiang and Jiangsu Provinces, 24 hours before the typhoons reach these areas. The hindcast of the historical typhoon surge and forecast of typhoon surge in 1987 we have done indicate that the method is satisfactory.

据说上了年纪,最好的锻炼方式就是早上散步。而这散步也有讲究,早了不好,说是夜间的暮气尚未散尽。太阳大了,晒出一身臭汗,也不好。最好是太阳刚出来时,一是可以欣赏到东边日出景象;二是初升的阳光具有天然蛋白,并且,通过那一照,空气清新了,吸进去大有好处。  不知道是不是这样,微信上一天一个学说,公说公有理,婆说婆有理,全信不行,但总得相信一个。S君就选择了这个,并且谨言笃行,于天天早上太阳欲出之时来到湖
