The Radial Sand Ridges(RSRs)area in the southern Yellow Sea are subject to tropical and extratropical cyclone activities frequently,in which the special geometry feature and moving stationary tidal system result in complex storm-induced hydrodynamic processes,especially the tide-surge *** studied a rare weather event influenced simultaneously by an extratropical cyclone EX1410 and Typhoon Vongfong as an example to investigate the characteristics of storm surges,wave-surge,and tide-surge interaction in the RSRs area,and applied a high-resolution integrally-coupled ADCIRC+SWAN model,in which the meteorological forcing inputs are simulated by the WRF-ARW *** model is validated by records from 4 tide gauges and 2 wave buoys along the Yellow Sea *** show that the tide-surge interactions are of considerable regional *** surge curves at Lüsi(in south RSRs)and Jianggang(in middle RSRs)have abrupt falls near the time of low tide,where the peak occurrence time of interaction residuals tend to shift towards the mid-ebb *** increase of bed shear stress in shallow waters was proved the dominant factor to affect the tide-surge interaction in broad tidal flats of the RSRs ***,the interaction pattern in the Xiyang Trough(in north RSRs),showed a unique rising in mid-flood period due to the phase advances of real surge waves in relatively deep ***,we suggested to the local flood risk management that the tide-surge interaction tends to alleviate the flooding risk in the RSRs area around the time of high tide,but aggravate the risk on the rising tide in the Xiyang Trough and on the falling tide in large-scale tidal flats of the southem RSRs area.

Because of the special topography and large tidal range in the South Yellow Sea,the dynamic process of tide and storm surge is very *** shallow water circulation model Advanced Circulation(ADCIRC)was used to simulate the storm surge process during typhoon Winnie,Prapiroon,and Damrey,which represents three types of tracks attacking the South Yellow Sea,which are,moving northward after landing,no landing but active in offshore areas,and landing straightly to the *** experiments were carried out to investigate the effects of tidal phase on the tide-surge interaction as well as storm *** results show that the peak surge caused by Winnie and Prapiroon occurs 2-5 h before the high tide and its occurring time relative to high tide has little change with tidal phase *** the contrary,under the action of Damrey,the occurring time of the peak surge relative to high tide varies with tidal *** variation of tide-surge interaction is about 0.06-0.37 m,and the amplitude variations of interaction are smooth when tidal phase changes for Typhoon Winnie and *** the interaction is about 0.07-0.69 m,and great differences exists among the stations for Typhoon *** can be concluded that the tide-surge interaction of the former is dominated by the tidal phase modulation,and the time of surge peak is insensitive to the tidal phase *** the interaction of the latter is dominated by storm surge modulation due to the water depth varying with tide,the time of surge peak is significantly affected by tidal ***,influence of tidal phase on storm surge is related to typhoon tracks which may provide very useful information at the design stage of coastal protection systems.

热带气旋是危害中国最严重的天气系统,分析和认识中国沿海登陆热带气旋活动的新特征对防灾减灾具有重要意义。依据近70年气象资料,采用统计学方法,对登陆中国沿海的热带气旋特征进行分析,研究发现:在气候变化的背景下,登陆中国的热带气旋发生了明显变化。近年台风登陆频数高于往年平均,其整体强度和最大值均呈增大趋势,年台风强度的不稳定性加剧;研究还发现台风强度越高,其生成地纬度带范围越窄且越靠近赤道;建立了高强度热带气旋(STY和SUPER TY)时间和纬度的关系"φ—m"。检验了台风季长与初旋日呈负相关且不受厄尔尼诺现象影响,台风季长符合正态分布并给出概率密度公式。

热带气旋(TC)登陆时中心最大风速会发生明显衰减,研究此时的风压关系对风暴潮模拟和预测具有重要意义。采用中国气象局上海台风研究所数据资料,对1949—2016年风压关系序列的一致性进行检验,登陆风压关系公式拟合及误差分析。结果表明:1970s后风压关系发生变异;新公式在计算登陆风速时要优于原公式,尤其是大风速情况下;相同气压下台风在近岸时风速明显小于大洋中,且登陆时风速越大衰减越剧烈。

1810号强台风"安比"是1990年以来直接登陆上海的最强台风,却并未诱发较大风暴增水。采用ERAInterim数据集作为背景风场资料建立了双重嵌套的高分辨率风暴潮与天文潮耦合数学模型,研究了台风"安比"在长江口地区风暴潮增水特征及成因。结果表明:台风期间增水主要集中在长江口北支出口沿岸,而长江口南支在台风登陆后出现明显的减水过程,台风登陆位置导致了长江口南、北支增水分布的差异;移行风对台风路径右侧增水影响更大,除梯度风场的向岸风作用外,落潮期间移行风场的作用致使连兴港附近岸段风暴增水平均增幅26.8%;除台风强度外,台风路径也是影响长江口地区风暴增水大小的重要因素之一。
