作者采用多维复合极值分布理论(Multivariate compound extreme value distribution)，以受台风暴雨危害较严重的浙江温州地区为例，对台风诱发暴雨的降水量进行了概率预测。

Design storm hyetograph is the essential element for hydrologic modeling analysis and storm water drainage design.

设计暴雨雨型对水文模式分析与暴雨排水设计是不可或缺的基本要素。

Several forms of design storm hyetograph have been developed in recent years. A Gauss-Markov hyetograph is based on non-stationary first-order Markov process. It is a dimensionless hyetograph and the most likely to occur is the average hyetograph.

暴雨雨型模式有许多种，本研究采用具尺度不变性之高斯马可夫雨型模式，该暴雨雨型模式视每一场降雨事件为一随机历程，考虑每个时刻之序列符合常态分布，以一阶高斯马可夫历程叙述临前水文条件的遗传效应，因此该雨型亦为具有最大概似度之设计暴雨雨型。

In order to evaluate service benefit of torrential rain forecasting quantitatively, a mathematical model was build with forecasting accuracy, percentage of coverage, time validity and damage preventability.

暴雨是江苏的重要气象灾害之一，为了对暴雨预报气象服务效益作出恰当的评估，我们设计了预报准确率V、预报服务覆盖率P、预报服务时效率N、可能预防能力Z等四个指标，给出了定量评估暴雨预报气象服务效益的数学模型，并且用实例说明了该模型的实用性和可操作性。

Observation of radar and intensive surface wind of 0505 typhoon Haitang is used to analyze the relationship between radar reflectivity and observed precipitation and the relationship between mesoscale surface stream field and heavy rainfall. The analysis shows that when the Doppler radar reflectivity reaches 50 dbz, it has a good correspondence to the heavy one hour precipitation. Besides, heavy precipitation is also related to the mesoscale cyclonical current and confluent currents, it occurs near the mesoscale cyclonical or confluent current appearing at the same time.

利用严重影响浙江东南地区的2005年05号台风的雷达和地面加密风场资料，分析对比台风中尺度暴雨过程中雷达回波与实况降水、中尺度地面流场与暴雨之间的关系，结果得到：多普勒雷达近地面强回波带或中心往往达到50 dbz时，与一小时的强降水区有很好的对应关系，暴雨中心区也与地面加密的中尺度流场中出现的中尺度气旋性环流和汇合气流有关，强暴雨区落在同时刻中尺度涡旋或汇合线附近。

Results indicated that population quantities of dominant species were seriously influenced by extreme climatic events:safety of passerine populations were influenced by sandstorms,hailstones and rainstorms;safety of migratory bird populations mainly by sandstorms hailstones and rainstorms,safety of rodent populations by rainstorms and safety of goat popula...

极端天气气候对优势物种数量影响严重。雀形目种群安全主要受到沙尘暴、冰雹和暴雨的影响较大；迁徙鸟类种群安全主要受到沙尘暴、冰雹和暴雨的影响较大；啮齿类种群安全主要受到暴雨的影响较大；岩羊种群安全受到沙尘暴、冰雹、暴雨和降雪的影响。

The objective of this study was to (1) explore the environmental, cultural, and hydrologic characteristics for sustainable development of San-Bu-Keng Creek watershed in Shangan area, Shuili Township, Nantou County,(2) investigate factors of causing debris flow such as terrain, geology, hydrology, land use,(3) evaluate the implemented watershed conservation and management strategies and suggest necessary improvements, and propose suitable land uses for sustainable development.

三廍坑溪集水区遇强度高、总量大的暴雨常发生土石流灾害，常造成下游上安社区发生屋毁人亡之惨剧。1996年贺伯台风、1999年的921地震造成水里上安地区溪流集水区源头裂缝、土层松动、坡地崩坏，其后2001年的桃芝台风暴雨更在三廍坑溪造成土石流灾害，计有死亡失踪17人，田园流失近百公顷，房屋全倒26户、半倒29户。造成灾害的原因包括陡峭地形、松散地质与台风暴雨等自然因子及滥垦滥伐，占用河道等不当土地利用。

On the long terms, the frequency and intensity of typhoon torrential rain both demonstrate the trend of increasing, but not significant in statistics; In addition, the frequency and intensity of torrential rain show some cycles, unsignificantly yet.

2中国台风暴雨的雨季是5至11月，其中7至9月是高峰期；台风暴雨频次存在很强的年际振荡和年代际的起伏；长期来看，频次和强度都呈现出上升的趋势，但在统计上是不显著的；另外，暴雨的频次和强度等存在一些准周期，但同样是不显著的。

On the basis of genetic analysis and flood time,the flood in Heilongjiang was divided into three types,that is ,storm flood, snowmelt and rain flood and ice flood in this paper.
