Therefore, the moist potential vorticity analysis associated with the mesoscale convective system was researched in the paper, so as to reveal the moist potential characteristics of mesoscale convective system in typhoon circulation. The results showed that, during the generation stage, convective instability characterized by MPV1 was a favorable condition for forming MCS, while the vorticity which was caused by the slantwise isentropic surface and the vertical shear of the horizontal wind characterized by MPV2 was an inspiring mechanism. The specific process was that, the atmosphere exhibited the feature of strong convective instability at the low level of convection areas and the southeast areas, which included plenty of erratic energy. The slantwise ascended the stream transfer the erratic energy to northwest, where the stratification stability was small. As decreased, the cyclonic vorticity increased. On the other hand, the vorticity caused by the slantwise isentropic surface and the vertical shear of the horizontal wind inspired the release of convective instability and as a result that the MCS formed. During the development stage, the cyclonic vorticity increased quickly with the persistent decreasing of . Meanwhile, the inclination of isentropic linewas bigger than the absolute momentum line at middle level, which exhibited the feature of conditional symmetric instability , then the conditional symmetric instability was forced to release by the vorticity resulted from the slantwise isentropic surface and the vertical shear of horizontal wind, and the MCS developed.

结果表明，在对流形成阶段，MPV1即对流不稳定为MCS的形成提供背景不稳定条件，由MPV2即湿等熵面的倾斜和水平风的垂直切变而引起的涡旋发展作为强迫机制：MCS形成的区域及东南区域中低层是强对流不稳定层，蕴含丰富的不稳定能量，倾斜上升运动把对流不稳定区具有强不稳定能量的暖湿空气向西北中层的中性层结区输送，由于的减小，气旋性涡度增强，有利于形成对流，另一方面，由于湿等熵面倾斜和低空急流加强而引起的涡旋发展作为一种强迫机制激发对流不稳定能量得到释放，从而形成对流；在对流系统地发展阶段，由于低层的对流不稳定性进一步减弱，进一步减小，气旋性涡度进一步增强，有利于MCS的增强，中层等θe 线的倾斜度比绝对动量M 等值线的倾斜度大，对应有条件对称不稳定区域，满足条件对称不稳定条件，在湿等熵面倾斜和台风低空急流作用下引起的涡旋发展强迫对称不稳定能量释放，从而使得对流得以维持和加强。

It is also shown that one of the most important reasons of the heavy rain amplification is the cold air which spreads to south from midlatitude in the lower troposphere and transports into the typhoon low pressure. The study of PV on isentropic surface shows the active state of the midlatitude cold air. The tropopause folding, which means that high PV spreads downward from the upper troposphere or stratosphere, helps the releasing of potential instability energy and the development of rainstorm.

分析表明：对流层低层中高纬度冷空气扩散南下在台风低压环流区附近的"侵入"作用是此次特大暴雨过程的最重要的原因之一；等熵面位涡的分析进一步说明了中高纬地区冷空气的活动状况；对流层高层或平流层低层高位涡的下传有利于位势不稳定能量的释放，使得暴雨增幅。

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。

In a word, it is an inevitable trend that offshore-cage-culture will develop rapidly, and offshore culture will be the direction offish mariculture in China In addition, the article points out that the laggard and small-scale management pattern is the source of the high production cost of offshore fish culture.

即使在当前条件下，如果将台风和病害风险考虑在内，深水网箱的优势已经开始显现。综上所述，深水网箱养殖的大发展是—个必然的趋势，深水网箱养鱼是我国网箱养鱼的发展方向。同时，作者认为，深水网箱养鱼成本偏高等现象只是当前行业发展中矛盾的表象，我国海水养殖业内落后的、小农式的生产经营方式才是问题的根本。

People have already foretasted some disasters of the future, Japan was hit by a record 10 typhoons and tropical storms this year; floods struck two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India, affecting 50 million people, destroying livelihoods and making tens of thousands

人们已经事先品尝到一些未来的灾难：今年，日本遭到创记录的10次台风和热带风暴的侵袭。孟加拉国2/3的国土、尼泊尔部分地区和印度东北的大部分地区均发生洪灾，影响5千万人口，毁坏了人们的生活，还造成数万人染病。去年，一场冬季寒流和夏季热浪夺走了印度两千多人的生命。

But the power of waves striking the shore can still be very great. During a winter gale, waves sometimes strike the shore with the force of 6,000 pounds for each square foot. That means a wave, 25 feet high and 500 feet along its face, may strike the shore with a force of 75 million pounds.Yet the waves, no matter how big or how violent, affect only the surface of the sea. During most raging storms, the water a hundred fathoms(600 feet) beneath the surface is just as calm as on a day without a breath of wind.Question: From your reading of the paragraph, which of the following is true?

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
