查询词典 wind and cloud

The complete wind turbine speed control firstly proposed here also improves the tracking effect of wind turbine rotating speed to variable wind speed. Wind turbine rotating speed synchronized power observer compensates the power ripple of wind turbine resulted in inverter dead time. A low pass filter used at the output of MPPT controller smoothes the speed reference, which makes the rotating speed of wind turbine more stable.

本文首次提出的变转速扰动的MPPT控制提高了风车最大功率点追踪的快速性和稳定性，风车完全转速控制提高了风车转速对变动风速的跟踪效果，转速同步风车功率观测法消除了逆变器死区所造成的风车功率波动的影响，带有低通滤波器的MPPT控制器使得风车的转速更加趋于平稳。

It has the advantage over single image in typhoon prediction. In the thesis, existing cloud motion wind algorithm is improved and a Cloud motion Wind Inferring System has been developed to derive wind fields from 2 or 3 infrared window images of FY-2C which are temporally continuous and projected by equidistance.

台风是严重影响人类生产生活的灾害性天气之一，对台风云系进行分析识别具有极其重要的现实意义，由于台风形态及结构的复杂性，单幅云图无法直观的分析其风场结构、移动趋势，通过云迹风分析，也可很好解决这样的问题。

It is presented that indirect assimilation experiment of CMW data from TCFM method improves effectively not only on vertical velocity field but for precipitation.4 Based on theory analysis, E-Ir relationship is brought forward with two electrification mechanisms. One is inductive mechanism, i.e., cloud particles collide with precipitation particles then flick away, the other is noninductive mechanism because of different temperature, i.e., bigger supercooled cloud particles collide and freeze with hail particles combined with ice scraps. By means of CINRAD and FY2C data assimilation, precipitation intensity Ir can be obtained, then electric field intensity E, discharge time and locations can be achieved with supposed threshold 300KV/m. Though it can not distinguish between IC (Intra-Cloud) lightning and CG (Cloud-to-Ground) lightning, results are still comparable to LLS observations.5 Example analysis shows that the relationship between precipitation data from AMS and CG data from LLS is not very clear.

同化实验对于台风眼区的螺旋形雨带贡献显著，说明TCFM云导风资料同化实验不仅有效调整了模式的垂直速度场，还对降水模拟有了明显改善。4通过理论分析，利用云粒子与极化降水粒子碰撞并弹离的感应起电机制和较大过冷云滴与雹粒碰冻并产生冰屑的温差起电机制下得到的E-Ir，由雷达、卫星遥感资料直接和间接同化模拟得到Ir，来反推E，了解雷暴云中闪电强度的平面分布，设置放电阈值为300KV/m，推算出放电的位置和首次发生闪电的时间。

The results showed that the mixed cloud and stratiform cloud were the main objective cloud,and the operation efficiency of stratiform cloud was the highest(80.5%).

结果表明：聊城市高炮、火箭人工增雨的作业以混合云和层状云为主要目标云系，层状云作业效率最高，可达80.5%。

Contemporary artificial rainfall is artificial rainfall basically is principle of basis nature rainfall, launch activator from the ground through the plane is spread or using tall artillery piece, rocket, wait like silver iodide, dry ice, liquid nitrogen, drop cloud layer temperature thereby, form supersaturation lunt; to perhaps condense to the boardcast sowing in the cloud layer that contains supersaturation lunt nucleus, increase the ice crystal amount in the cloud, increase the amount of drip-drop and diameter then, raise cloud precipitation change rate, achieve the goal that raises precipitation of bureau ground nature thereby.

二、现代的人工降雨人工降雨主要是依据自然降雨原理，通过飞机播撒或利用高炮、火箭从地面上发射催化剂，如碘化银、干冰、液氮等，从而降低云层温度，形成过饱和水汽；或者向含有过饱和水汽的云层中撒播凝聚核，增加云中的冰晶数量，进而增加雨滴的数量和直径，提高云降水的转化率，从而达到增加局地自然降水的目的。

In each kind of different cloud, its cloud drop size distribution isvarious, creates the cloud drop size uneven reason is in thesurrounding air the water vapor shift as well as cloud dropevaporating.

在各种不同的云内，其云滴大小的分布是各不相同的，造成云滴大小不均的原因就是周围空气中水汽的转移以及云滴的蒸发。

There are some main conclusions as follows:1、 In Inner Mongolia, Mean cloud amount, low cloud amount, middle cloud amount , liquid stratocumulus liquid stratus、 ice stratocumulus、 ice stratus、 ice nimbostratus cloud amount are getting more from west to east.

主要研究结果如下： 1、内蒙古地区总云量、低云量、中云量、液态层积云、液态层云、冰像层积云、冰像层云、冰态雨层云云量呈自西向东依次增多，高云量、卷层云、深对流云云量自西南向东北依次减少的空间分布特征。

Lives simply is theacademic honor benefits of rank and salary, the contempt appraises thehonor or disgrace, treats the humans affair with 平常心 the windand cloud transformation, the rise and fall, can maintain the soberbrains; Can like Wang Anshi,"the fear floating clouds not obstructlooks the eye, only reason body in topmost story"; Can like the Soviethorizontal wooden board on the front carriage body,"蓑 misty rain nomatter what always, also does not have the wind and rain to be alsoheartless", can look in front of the courtyard 花开花落, looks thespace cloud volume cloud to extend!

淡泊的是功名利禄，轻视的是褒贬荣辱，用一颗平常心来对待世事的风云变换，起起落落，才能保持清醒的头脑；才能如王安石，&不畏浮云遮望眼，只缘身在最高层&；才能如苏轼，&一蓑烟雨任平生，也无风雨也无情&，才能看庭前花开花落，望天上云卷云舒！

Soil erosion by wind, as a natural disaster haunts on dry lands, not only degrades soil productivity but also often results in dust blizzard weather. It may cause pollutions of air and water, damages of highway and railway, wear and tear of buildings and machinery and harmfulness in health of people and animals. Therefore, to combat wind erosion means improving the environment for people to live and work, means heightening the living standard of the local people, and means promoting productive forces. But China has a vast land where probably occur wind erosion disasters, the arid, semiarid and subhumid areas of the temperate zone all are potentially hit by wind erosion. To control wind erosion in China is a very arduous task. More difficult is to achieve recognizable effectiveness with lowest cost.
