降水现象

结果表明，中尺度海-气-浪耦合模式系统能够良好的模拟台风所产生的海面SST下降、风暴潮、狂风巨浪和台风降水等等现象，且与观测吻合良好。

The simulation results showed that MCMS can well simulated the response of sea to the typhoon , such as decrease of SST , storm surge , high wind and huge wave , typhoon rainfall , etc. The results were well consist with the observation .

城市化改变了局地的动力学和热力学特征，对降水天气现象必定有一定的影响。

Urbanization has changed the local dynamics and thermodynamics features , which must have a certain effect on rainfall .

当ELNino年有正IOD事件同时发生时，我国北方地区水汽增加，华北降水偏少现象得到抑制，我国大陆气温有所上升；

When a positive ( negative ) IOD event co-occurs during an El Nino ( La Nina ) year , the moisture content and precipitation tend to increase ( decrease ) in the northern part of China .

降水量减少现象在冬季（12-2月）最严重。

The phenomenon of reduced precipitation is the most serious in winter .

旱涝和降水异常天气现象发生的概率增大；

The probability of the extreme weather events , such as the drought or flood and precipitation anomalies increased .

本文首先对基坑工程的研究现状以及引起的对周围环境的影响作了较为详细的论述，并着重对基坑工程降水产生的不良现象进行分析。

The foundation pit effects on the surroundings is firstly discussed in detail , and the bad phenomena caused by pit dewatering is emphatically analyzed in this paper . Summarization of the settlement induced by dewatering is also displayed .

凝冻是指冬季出现的温度低于0℃，有冷却降水或固体降水和结冰现象发生的天气现象，它是在特定的天气条件下形成的，并具有高度局域性。

Freezing is the weather phenomena that the temperature is below 0 ℃ in winter , and the cooling and freezing precipitation or solid precipitation and icing phenomena . It is the formation in particular weather conditions , and highly localized .
