13. The wind: atmospheric level motion is called wind, the level of pressure gradient force is the direct cause of the formation of the wind, isobar more dense wind speed.

14, the wind direction: (1) the direction of the wind to;

(2) according to the wind direction distribution: right to determine the isobars for example painting point A and wind stress

To determine the level of pressure gradient force in the direction perpendicular to the isobars: by high and low pressure point

To determine the direction of the direction of the earth rotation: with the direction of the wind direction, the right side of the northern hemisphere, the left side of the southern hemisphere.

The near ground by the friction force (direction and wind direction) effect, the wind direction and the oblique isobars

15, the upper atmosphere wind direction is the pressure gradient force and geostrophic interaction bias of the results, the wind direction and parallel to the isobars;

Wind near the ground, by the pressure gradient force, Coriolis force and frictional force, the direction with the isobars into an included angle.

16, the front and the weather (warm and cold air mass movement and meet as standard)

The cold front in front after the rain, rain and snow, cool weather. After crossing, the pressure increases, the temperature dropped, the weather clears;

The warm rain in front of transit, for continuous precipitation. After crossing, temperature rise, pressure drop, sunny weather.

17, affect our weather the main front is cold front, such as North China summer rainfall and winter cold in China, winter and spring sandstorm.

18, air pressure system and the weather (the same air vertical motion):

A cyclone (low pressure) vertical air flow is increased, and the weather is overcast and rainy. The vertical air flow of the anti cyclone (high pressure) is in a fine weather;

19, three circulation and wind pressure:

Three circle circulation (vertical distribution)

Draw the right three circulation loop diagram

The pressure zone, the wind (level distribution)

Draw the right pressure zone, the distribution map

("left North South Na")

The Great Wall inspection station red flag to the northwest, windows to avoid the Southeast direction;

The Yellow River inspection station, the red flag to the southwest, windows to avoid the Northeast direction.

Mobile 20, atmospheric pressure and wind: moves with the moving sun point.

Direction of movement: on the northern hemisphere, summer is generally northward, southward in winter

21, the monsoon circulation: Asia Pacific sea land thermal difference, the center varies with the season of:

Summer: Asian continent on the formation of low pressure on the formation of Asia Pacific, Hawaii, the formation of high pressure;

Winter: the formation of Asian high Asian continent, the formation of the Pacific Aleutian low.

22, East Asia, South Asia monsoon circulation: (right)

East Asia: the southeast wind in summer, winter northwest wind; thermodynamic properties are mainly caused by the difference between land and sea.

South Asia: Summer southwest wind, winter northeast wind, by the wind belts and pressure with seasonal movement and land sea thermal differences in the nature of the interaction of formation.

23, China's drought and flood disaster, rain mobile and subtropical high intensity has a close relationship.

Move rainband

At the end of spring (May), Southern China (rain in Pearl River Basin (North China) spring, northeast spring)

Early summer (6---7 months), the rain moved to the middle and lower reaches of Yangtze River,

Meiyu (quasi Zhi Feng)

7--8 months, the rain moved to the northeast and North China, the Yangtze River into the "dry" (anticyclonic)

In September, the south north subtropical high back, the end of the rainy season, the south into the second season.

The rainy season begins at the beginning of the rainy season in North China, the rainy season is short, and the rainy season begins early, and the rainy season is long.

The drought and flood disaster faster (north subtropical summer monsoon strong), caused by the northern South drought waterlogging

The subtropical high northward slow (summer monsoon), causing flooding in North and drought in South.

The root cause of flood and drought disasters occurred in China is: the intensity of summer monsoon and retreat sooner or later.

24, climate formation factor: solar radiation, atmospheric circulation, the underlying surface, human activities

25, judging the type of the climate of the steps: the judgment of the northern and southern hemispheres, the judgment of the heat, and to determine the rain type.

Four types of climate of the tropics: the monthly average temperature in 15 different degrees, precipitation, climate type is different

Tropical rain forest climate (affected by the low temperature, high temperature and wet).

The tropical desert climate (perennial subtropical high from the land or the trade winds, at high temperature and less rain)

Tropical monsoon climate (South Asia, the prevailing northeast monsoon in winter, for the dry season, the southwest monsoon winds, 6--9 months for Yu Ji)

Tropical steppe climate (equatorial low shuffled around, is the wet season, trade shuffled around for the dry season, agricultural activities is sown in the rainy season, dry season harvest)

The subtropical climate types: winter average temperature of the coldest month in more than 0 degrees, the world's only two types of climate:

Mediterranean climate: except Antarctica, and that of the other continents are distributed, in the

north and south latitude 30o - 40o, the West Bank, between the position within the Westerlies and the subtropical high, mild and rainy winter, hot summer drying

Subtropical monsoon climate: winter, north wind - low temperature, high temperature and rainy summer, summer wind.

The temperate climate type: in addition to the marine climate, the winter average temperature of the coldest month to 0 DEG C.

Temperate marine climate: located in the north and south latitude 40o--60o, West Bank (Mediterranean climate of high latitudes side), aged from westerly wind control, year-round mild and rainy

Temperate monsoon climate: distribution in latitude 35o--55o the eastern coast of the continent (subtropical monsoon high latitudes side), affected by the winter wind, cold and dry, and by the summer winds, hot and rainy.

Temperate continental climate throughout the year by the continental air mass control, large diurnal, annual, scarce rainfall, precipitation mainly in summer.

26. The different characteristics of continental and oceanic climate (taking the northern hemisphere as an example):

初中英语语法基础知识汇总形容词

初中英语语法基础知识汇总 形容词adj. 形容词的定义和用法： 定义：形容词用来修饰名词或代词, 表示人或事物的性质, 状态,和特征。形容词在句中作定语, 表语, 宾语，补语。 She is a good student, and she works hard. 她是一个好学生,她学习努力。 This bike is expensive. 这辆自行车很贵。 I am sorry, I'm busy now. 对不起,我现在很忙。 Have you got everything ready for the meeting? 你为这次会议做好准备吗? 形容词在句中的位置: 形容词作定语一般放在被修饰的名词之前。如果有两个或两个以上的形容词修饰一个名词时, 则由它们和被修饰的名词之间的密切程度而定, 越密切的形容词越靠近名词。如果几个形容词的密切程度差不多则按音节少的形容词放在前面, 音节多的形容词放在后面。 英语单词中,something, anything, nothing 等不定代词被形容词修饰时,形容词放在名词后面。 I have something important to tell you. 我有重要的事要告诉你。 Is there anything interesting in the film. 电影里有什么有趣的内容吗？ There is nothing dangerous here. 这儿一点都不危险。 由两个或两个以上的词组成的形容词词组修饰名词时须放在名词之后。 This is the book easy to read. 这是一本容易读的书。 用and 或or 连接起来的两个形容词作定语时一般把它们放在被修饰的名词后面。起进一步解释的作用。 Everybody, man and woman, old and young, should attend the meeting. 每一个人,男女老少,都应该参加会议。 You can take any box away, big or small. 这些箱子，不管大小，你都可以拿走。 形容词的比较级和最高级： 绝大多数形容词有三种形式,原级,比较级和最高级, 以表示形容词说明的性质在程度上的不同。 形容词的原级: 形容词的原级形式就是词典中出现的形容词的原形。例如: poor tall great glad bad 形容词的比较级和最高级: 形容词的比较级和最高级形式是在形容词的原级形式的基础上变化的。分为规则变化和不规则变化。 规则变化如下: 1) 单音节形容词的比较级和最高级形式是在词尾加-er 和-est 构成。 great (原级) greater(比较级) greatest(最高级) 2) 以-e 结尾的单音节形容词的比较级和最高级是在词尾加-r 和-st 构成。 wide (原级) wider (比较级) widest (最高级) 3)少数以-y, -er, -ow, -ble结尾的双音节形容词的比较级和最高级是在词尾加-er 和-est 构成。 clever(原级) cleverer(比较级) cleverest(最高级) 4) 以-y 结尾,但-y 前是辅音字母的形容词的比较级和最高级是把-y 去掉,加上-ier 和-est 构成. happy (原形) happier (比较级) happiest (最高级) 5) 以一个辅音字母结尾其前面的元音字母发短元音的形容词的比较级和最高级是双写该辅音字母然后再加-er和-est。
