降水

It suggests that the horizontal momentum of the meso-cyclone was brought down to the surface by heavy rain. At the right edge of meso-cyclone the momentum and RIF have the same direction, the two airflows overlay together and make the wind increase, so damage wind occurred.

分析认为，弓状回波后部存在较强后部下沉入流，由于强降水的拖曳作用，将中层中气旋的水平动量带到地面，中气旋右侧动量的方向与弓状回波后部的强下沉入流方向一致，两者叠加，使地面风速加大，造成灾害性大风。

Wall-rock metasomatism, boilings and separation of fluid facies, as well as mixture with meteoric water were the main evolution processes in a fluid system. The activiti es of ore-bearing fractures can be divided into two states: brittle and brittle -ductile ones.

与围岩的交代作用，沸腾作用引起的相分离和大气降水的加入所产生的混合稀释是成矿流体体系演化的主要途径，容矿断裂构造活动可划分为脆性破裂和韧脆性扩张两种动力学状态。

Budgies travel in large flocks in the wild, especially during the time right after a season of abundant rainfall; flocks at that time are around tens of thousands, but normal flocks can range from one to three hundred.

budgies旅行，在大鸡群在野外，尤其是在正确的时间，一个赛季后的降水偏多；成群当时大约有数以万计的，但正常的鸡群，可射程为1至300 。

Firstly, rainfall rate structure in horizontal and vertical of Typhoon Dans precipitation cloud system at 3 different times during its life period is studied based on the data from PR 2A25 data.

首先，利用PR的标准资料2A25，研究了9914号台风降水云系在三个不同时次雨强的水平和垂直结构。

The reasons of water cycle being destroied are as follows: Because of the forest-steppe vegetation destroied and water and soil erosion, water resource conservation layer is destructed, and surface water and groundwater of mountainous areas is also damaged. Groundwater is damaged as a result of poor drainage of mining industry. The river channelization destroies surface water and wetland groundwater. The plain groundwater is damaged because of excessive exploitation. The decreasing of actual evaporization destructs precipitaion cycle.

发现了自然水循环各环节被破坏的原因：森林草原植被破坏和水土流失，破坏了水源涵养层，破坏了山区地表水和地下水；矿业不良排水破坏了山区地下水；河流渠道化破坏了地表水和湿地地下水；过量开采破坏了平原地下水；陆地实际蒸发量的减少，破坏了大气降水循环。

The wind convergence, mesoscale cyclone and vertical wind shear at lower levels may produce heavy rainfall. The mesoscale cyclone and vertical wind shear at middle and upper levels may produce strong downburst or hails.

低层水平风的辐合、中气旋、垂直风向切变等可以产生强降水，中高层的中气旋、垂直风切变可以产生下击暴流、冰雹等强对流天气。

From the stand point of view of China's present rural economical state, the changeable weather conditions and the goal of keeping grain quality etc, it illustrates the necessity and feasibility of developing and popularizing small grain driers for agricultural application.

讨论了发展粮食机械干燥降水的重要意义，并从我国农村经济的现状、多变的气候条件和保持粮食的品质等方面出发，阐述了开发与推广农用小型谷物干燥机的必要性和可行性。

Combining the dusters level by level through a synergistic method, the objective of the data sets clustering had been achieved.

将该方法应用于2006-2007年中国及周边亚太地区FY-2C卫星云图的聚类分析，得出不同降水类型的云图特征。

And the westward ISO is usually the low-frequency low and high pressure systems from the Bay of Alaska in northeastern Pacific and the Okhotsk in the northwestern Pacific of mid high latitudes, and the ISO evolving in subtropical easterlies.

进一步分析发现，经向风ISO的纬向传播对应着大气经向型环流系统的移动，向西传影响东亚夏季风区降水的ISO有来自低纬中东太平洋东风流中的低频气旋（如副热带东风带中ISO的演变）；也有来自中高纬度阿拉斯加湾及鄂霍次克海一带低频低压和高压(如阻塞高压和东北太平洋高压)的向南向西频散。

E. , approximately four months; 2 the active periods occur much longer than the non-active periods; the main climatic characteristics of the non-active periods, compared with the active periods, is weaker monsoon with westerlies at 850-hPa and easterlies at 200-hPa on the deviation fields of circulations over the SCS (active time minus non-active time); it is warmer in the active periods than in the non-active periods at lower and upper levels; 3 in most circumstances, the low frequency vibrations of the summer monsoon and its rainfall are quite in phase.

2其中活跃期出现时间要比非活跃期长的多。与活跃期相比非活跃期主要气候特征表现为季风的减弱，在环流的偏差场上在南海上空850hPa上为西风，200hPa上为东风，活跃期高低空都比非活跃期要暖一些。(3)在多数情况下夏季风和夏季风降水的30-60天的低频振荡比较一致。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
