The wind fields andtemperature fields data provided by "D files" from 14 surface observationstations around Beijing area are used to produce the mean wind fields and the meantemperature fields over Beijing area in summer and winter. Such results are gotten:(1)Due to the unique topography the wind of Beijing area during the day time is southernanabatic wind and in the night is northern katabatic wind in summer.

采用多元逐步回归方法和关联分析法得出的气候因素对日本落叶松生长量影响的排序次序是有差异的，但基本结论具有共同性：影响重要的气象因子不管是上年夏季的降水量，还是上年9～10月相对湿度都与降水有关，表明该地区日本落叶松生长量与降水状况和春季地温有密切关系。

In an apocalyptic forecast, Claude Mandil, the agency's executive director, said that our current path "may mean skyrocketing prices or more frequent blackouts; can mean more supply disruptions, more meteorological catastrophes – or all these at the same time".

The analyses of the meterological and oceanographical data from seriel observations aboard R/V Xiangyanghong 5 during the voyage of joint AMEX experiment by Australia,China and the United States show that (1) there is high level of humidity within middle and low layers of troposphere at the initial stage of a typhoon's formation,and once a typhoon has fully developed,the highest level of humidity remains within middle layer of tropisphere;(2) although small vertical wind shear is a requisition for a t...

对中、美、澳三国AMEX试验期间&向阳红5号&定点观测到的气象和海洋资料分析得出：①台风形成前，大气整个中、低层空气湿度较大，台风一旦形成，大气湿度最大层主要集中在中空；②风速垂直切变小，对形成台风是一个必要条件，但并非整个对流层风速切变都小，而且不同地区形成的台风，风速切变状况是不同的；③厄尔尼诺年南半球与北半球对应位置同期的θ_G、θ_8、Q_b相差不大，但是南半球的θ_c较北半球的大。

This method also can be applied to many areas that need to handle a tremendous amount of data, for example in the industrial, medical or meteorological area etc.. We can use this method to diagnose and prognose results after the junction tree is built.

同样的方法可应用在很多领域上，如类似制程的自动化科技上、大量病历资料的医学上、大量数据的气象上…等等各种需要处理大量资料的领域，都可以应用此方法来进行诊断和预测的工作。

They do not express mainly the theme of recentness,but lofty spirit of concerning the country and people,which therefore finishes the change of Wang Zhaojun's image from a resent girl to a lofty one.

昭君出塞历来是中国古代诗歌创作的重要题材，历来均是以表现怨情为主，但是宋代的一些昭君诗却表现出了全新的气象，不再以怨为主，而表现出了心忧天下，志在为国为民的崇高思想，从而完成了从怨女到义女的转变。

The result of clusting analysis of 52 counties and cities in northeast Chinawas the division of the risk grade of poplar bacterial canker into 4 districts thatwere seriously occurring district、commonly occurring district、occasionally oc-curring district and unoccurring distric,according to nine weather factors whichwas closely correlated to the bacterial canker.

以与病害密切相关的九项气象因子为指标，对东北地区52个市县进行聚类分析的结果，将东北地区杨树细菌溃疡病的危险等级划分为重发区，常发区，偶发区和不发区四级，这与病害调查的实际情况也是基本一致的。

For strong convective weather , it classified all historical sample events into 4 weather patterns (like northwest , trough area ,west wind and southwest current), established 4 characteristic fields of 400hPa height of HLAFS , then according to the principle of the pattern match calculate and compare the real-time HLAFS forecast products-2-using the similar method inside the big and small key areas , establish forecast equation , finally gain conclusion .To duststrom weather, the historical samples were sorted into duststrom and severe duststrom types in 5 regions (they are whole area, west, central, middle-west and middle-east of Inner Mongolia ),moreover set up different sample databases about ECMWF fields (including 500hPa height, 850hPatemperature and sea-level pressure).In order to making duststrom forecast at different time level , we first filtered the real-time data by FAX data ,and then used the method of similar range degree to compare the historical data to the actual data of ECMWF .To precipitation weather ,they were divided into 2 types that suit or unsuit airplane artificial precipitation stimulation in line with their emergence time and district .The appropriate weather physical factors come from T106 were chosen to establish the artificial precipitation stimulation prediction model . In the actual application , we can get prediction result as long as use the real-time forecast data of T213 in the prediction model .

针对强对流天气将历史样本天气分为西北气流型、槽区型、西风气流型和西南气流型等4个类型，并建立其HLAFS资料400hPa四种特征场，按照模板匹配的原理，用相似分析方法在大、小两个关键区中对实时HLAFS预报产品进行计算、比较，再建立预报方程，得出结论；对沙尘暴天气将其按区域分为全区、西部、中部、中西部以及中东部5类，再按强弱分别分为强和一般2类，建立ECMWF的3个场(500hPa高度场、850hPa温度场和海平面气压场)的历史资料库，在用传真资料消空之后，用相似离度方法计算实时ECMWF资料，做出不同时次的预报；对降水天气按出现时间和区域分为适合和不适合飞机增雨作业2类，选择T106资料中恰当的气象物理量因子，用BP神经网络算法建立人工增雨降水预报模型，实际应用中将实时T213相关预报资料代入预报模型即可。

PID control has been successfully used in many fields such as aviation, spaceflight, missile and other industry control system. The study object in the thesis is missile that flies hedgehopping over sea at minimum altitude. Many interference problem must be solved when missile flies at minimum altitude, otherwise the missile would be dangerous of bumping into the sea under the circumstances of bad weather and wave. The different kinds of interference factors are contradictions with requirements of control system, which can not be solved by PID control.

尽管在航空、航天、导弹以及其它工业控制领域PID控制曾经应用的十分普遍和成功，但对本文所研究的某型超低空掠海飞行的导弹，要实现超低空飞行必须处理好各种干扰问题，否则，在恶劣的气象和海情的条件下便有使导弹与海浪相撞的危险。

Opened a modern history, the book has confused Nanhu Rain Red Boat despite struggling to start, there are anti-Japanese fighters in the sky straight blood, there are clip-clop broken, trumpet Pathos pharynx, there are Cangshan sea, setting sun, such as blood Weather , there are thousands of miles of , the book is more of a straight after another fearless, light yushu!

翻开近代史，书中有南湖红船迎着迷茫烟雨艰难地起航，有抗日战士直冲云天的热血，有马蹄声碎、喇叭声咽的悲怆，有苍山如海、残阳如血的气象，也有千里跃进万马奔腾的豪壮，书中更有一曲曲直冲霄汉、光照九州的正气歌！
