雨滴

I felt a drop on my head.

我感觉到有雨滴落在我的头上。

Raindrop beats my window, seems eidolon say hello.

雨滴敲打着窗子，像精灵在向我打着招呼。

The black soil in Northeast China had a stable soil structure, and raindrop beat was the dominant factor resulting in the development of crust. During the process of rainfall, no obvious eluviation was observed.

东北黑土结构稳定，雨滴打击是其结皮发育的主导因子，降雨过程中未发现明显的颗粒淋移现象。

A raindrop may luk 2 small 2 eyes but sumwhere a thirsty flower await its fall.

一颗雨滴看起来这般渺小，可某处一支干渴的花儿正期待它的降落。

On the basis of Fourier Synthesis,this paper realizes a special animation procedure,that is the transformation state of the waves when raindrop falling into water.

文章基于Fourier合成技术对雨滴下落产生的水波这一特殊物理现象进行了计算机动画合成。

This paper proposed a geomorphologic instantaneous unit hydrographwith gamma type probability density function.

在形态定量律基础上提出了雨滴沿"路径"的等待时间密度函数成Γ型分布的地貌瞬时单位线。

Several microphysical processes are deeply improved comparing with explicit microphysical schemes of MM5 and some cloud models, such as deposition, freezing, ice nucleation, and autoconversion of cloud to rain, ice to snow, snow to graupel.

新方案对冰晶的核化、雨滴的冻结和霰的凝华等物理过程的描述有较大的优势，云雨自动转化、冰雪自动转化和雪霰自动转化中没有给定的阈值，减少了人为性。

At the same time ice crystal and graupel collect more supercooled rain water to reduce the amount of rain water. Graupel grows through the collection of ice crystal and graupel with supercooled rain water and riming of cloud water.

霰融化、霰在暖区碰并云滴成雨减少，使雨滴的初生减弱，而冰晶碰并过冷雨成霰、霰碰并过冷雨增加，也消耗了过冷雨水，抑制雨水增长。

Numerical tests are also conducted to investigate the microphysical effects to the mesocale convective systems. The evaporation of raindrops can strengthen the surface "cold pool" to decease the temperature of rainfall center. The condensation of vapor can lower the air pressure and increase the convergence and updraft so that the convective echo develops stronger. The melting of graupel can cool the air to restrain the convective activity. The falling of precipitation particles can increase the downdraft and induce the outflow nearly the surface. The effect of condensation is the most important among all the microphysical processes. It can change the whole structure of cloud system.

微物理过程对对流系统发展和维持有重要作用：强降水的雨滴蒸发过程会加强"冷池"效应，同时增强了雨带南侧原有的地面中尺度辐合线；凝结潜热在低层诱发了与回波相应尺度的中尺度低压，增强了辐合和上升运动，促进对流发展；霰的融化吸热通过冷却大气会不利于气压下降、气流辐合抬升等过程，降低对流不稳定能量，减缓对流发展；重力拖曳使气块冷却降温，降低对流不稳定能量，并且使低层的气压升高、气流辐散，在近地面附近产生出流，加强地面中尺度辐合线的强度。

It seems as if nature had saved all her ruggedness to pile it up in this colossal form of the Guadalupe Peak

这些巨大的峰塔似乎随时都会落下，而这些巨大的石头似乎已经准备好了，只要有一个雨滴，就能松开维系它的结而越来越快地落到松软的底面，在这些巨大石头下落的沿途，它们将摧毁一切。

Do you know, i need you to come back

你知道吗，我需要你回来
