Knowledge points of geographical atmospheric movement in senior high school

Knowledge is really a wonderful thing. You just-you just dabble, so you just get bored and treat learning as a task. But if you explore deeply, you will find the wonder of life and know a lot of things you don't know. Below I will share some knowledge about geography and atmospheric movement in high school, hoping to help you. Welcome to read!

High school geography and atmospheric movement knowledge 1

1, the characteristics of troposphere: ① the temperature decreases with the increase of height; ② The atmospheric convection motion (12km) is remarkable; ③ The weather is complicated and changeable.

2. Characteristics of stratosphere: ① Temperature increases with height; (2) Atmospheric stability, mainly horizontal movement, is conducive to high-altitude flight.

3. Thermal process of the atmosphere: solar radiation-ground warming-ground radiation-atmospheric warming-atmospheric (inverse) radiation-atmospheric insulation.

4. Weakening effects of the atmosphere on solar radiation: absorption, reflection and scattering.

5. The relationship between solar radiation (illumination) and weather and topography: sunny weather, high terrain, thin air and stronger illumination; The distribution of solar energy in China is the highest in Qinghai-Tibet Plateau and the lowest in Sichuan Basin.

6. Heat insulation of the atmosphere: strongly absorb long-wave radiation on the ground and return heat to the ground through atmospheric reverse radiation.

7, temperature and weather: cloudy during the day, the temperature is not high (strong cloud reflection); Cloudy at night, high temperature (strong atmospheric inverse radiation).

8. Vertical distribution of temperature: Tropospheric temperature decreases with the increase of altitude.

9. Horizontal distribution of temperature: ① Latitude distribution: The higher the latitude, the lower the temperature. The area with the richest heat in China: Hainan Island.

② Land and sea distribution: land > sea in summer, sea > land in winter;

(3) Where the temperature is high, the isotherm protrudes to the high latitude; On the contrary, where the temperature is low, the isotherm protrudes to the low latitude.

10, temperature annual range: ① influencing factors: thermal properties of land and sea; Water status of surface vegetation; How much sex and rain.

② Variation law: inland > coastal and continental climate >; Marine climate, bare land > grassland > woodland > lake, sunny day > cloudy day.

1, the characteristics of thermal cycle

(1) Where the ground is hot in the horizontal direction-vertical airflow rising-low pressure (cyclone)-rainy.

(2) The place near the ground in the horizontal direction is cold-vertical airflow sinks-high pressure (anticyclone)-sunny.

(3) Vertical temperature and pressure distribution: With the increase of altitude, although the temperature decreases, the air becomes thinner and the pressure decreases.

(4) Air flow from low latitudes-warm and humid; (5) Airflow from high latitudes-cold and dry.

(6) Airflow from the ocean-wet (7) Airflow from the mainland (land wind)-dry.

(8) Two different air currents meet-front-rain and wind.

2. Air pressure and temperature in the horizontal direction: the temperature near the ground is high, the air expands and rises, and the ground forms a low pressure; On the contrary, when the temperature is low, the air near the ground contracts and sinks, and high pressure is formed on the ground.

3. Formation of wind: The horizontal movement of the atmosphere is called wind, and the gradient force of horizontal air pressure is the direct cause of wind formation. The denser the isobar, the greater the wind speed.

4. Wind direction: (1) Wind direction-the direction of the wind;

(2) Determine the wind direction according to the isobar distribution: Take the figure on the right as an example, draw the wind direction at point A and its acting force.

① Determine the direction of leveling pressure gradient force: perpendicular to isobar, pointing from high pressure to low pressure.

② Determine the geostrophic deflection direction: vertical wind direction, right in the northern hemisphere and left in the southern hemisphere.

(3) The near ground is affected by friction (the direction is opposite to the wind direction), and the wind direction is oblique to the isobar.

5. The wind direction of the upper atmosphere is the result of the joint action of pressure gradient force and geostrophic deflection force, and the wind direction is parallel to the isobar;

The wind near the ground is influenced by the pressure gradient force, geostrophic deflection force and friction force, and the wind direction forms an angle with the isobar.

6. Fronts and weather (air masses with different temperatures meet when moving horizontally)

① The cold front passes through the rain area behind the front, and there is rain and snow to cool down. After crossing the border, the air pressure increased, the temperature plummeted and the weather turned fine;

② The warm front crossing rain area is in front of the front, and most of it is continuous precipitation. After crossing the border, the temperature rose, the air pressure dropped and the weather turned fine.

7. The main front affecting the weather in China is the cold front, such as the rainstorm in summer in northern China, the cold wave in winter and the sandstorm in winter and spring.

1. Names of seven continents and their ranking by region:

Asia, Africa, North and South America, Antarctica and Europe.

2. The world's major mineral resources:

Coal, iron and oil are the three most important minerals in the world. Russian, Pakistani, China, Australian, Indian, Canadian and American, these seven countries have large iron ore reserves.

In Eurasia and North America, coal mines are well distributed. Oil is relatively concentrated, with more than half in the Middle East.

3. Names of ten countries with a world population of over 100 million:

No other country in the Antarctic Ocean has a population of more than 1 100 million. China and the United States, India, Russia and Pakistan, Japan and Nepal plus Bangladesh.

4. Names of five Central Asian countries:

Hajita is even my shoulder, on the salty sea in Uzbekistan. On the shores of Caspian Sea, Turkmenistan and five Central Asian countries depend on each other.

5. Central Asia knowledge summary:

Central Asia is far from the ocean, so it is difficult for Leng Xia to get hot precipitation in winter. Vegetation has grassland and desert, and there is Kaku desert in the southwest.

The eastern and southeastern areas are relatively high, between the boundaries of Tianshan Mill. The north and west are hills and plains, and the largest are Haqiu and Tulan.

Most rivers flow inward, and the amount of water in Siram decreases. The Caspian Sea is the largest sea in the world, and the Aral Sea is in crisis.

The output of cotton fields in earthen warehouses increased, and fortifications were built in the Kaku Canal. The Irtysh River flows out, flows through the Three Kingdoms and crosses northward.

The cotton production base is second only to China and the United States, thus spreading the reputation of "Platinum Country". Many nationalities believe in Islam, and Tashkent is the largest city.

6. Names of China and the United States:

(1) There are seven countries in Central America, namely Belize. Spain, Hong, Nepal, Colombia and Panama are famous for their banana coffee.

(2) The seven countries of China and the United States will always remember the danger of flood (Sa), mud (Ni), brothers and fathers (Ba) leaving (Belize).

7. Great Lakes of North America:

(1) The Great Lakes of North America, Sammi Flower.

(2) The Great Lakes of North America are connected in groups. Under the action of glaciers, lakes were formed. There are four in the United States and Canada, and the middle is clear. Erie, Ontario, Sotheby's and Lake Huron. Another kind of beauty is unique, called "Michigan". The total area of the five lakes ranks first in the world. Fresh water resources are abundant, which is especially beneficial to shipping.

8. American agricultural belt and its distribution;

American farming belt, central winter wheat, northern spring wheat. Great Lakes region and northeast China, typical dairy farming belt. The southern region has good conditions and has become a concentrated corn belt. In the plain area of the lower reaches of Mihe River, cotton is as white as the sea. In the western mountainous plateau area, both animal husbandry and agriculture need irrigation.

9. Geographical location of West Asia and North Africa:

Asia, Europe and Africa are closely linked and surrounded by the sea. The Silk Road connects things, and the transportation by sea, land and air is very convenient. Adjacent to the oil region of the Persian Gulf and the northwest end of the Caspian Strait. Suez, the North-South Canal, a short voyage between three continents and two oceans.

10. Climatic characteristics of Latin America:

Most of "Latin America" lives in low latitudes, and the tropical climate is dominant. With plenty of heat and precipitation, the word "warm and wet" is subtle. There are differences on both sides of "Anshan", and the seasons are opposite from north to south.
