"Main Factors Forming Climate" PPT

Factors that shape climate:

1. Natural factors (main factors)

latitude factor

sea ​​and land factors

terrain factors

2. Human factors

Indiscriminate cultivation and deforestation

overgrazing

Analysis: Climatic characteristics of Hainan and Mohe

Why is the temperature difference between the two places so large?

latitude factor

Temperature: The temperature in high latitudes is ________,

Temperatures at low latitudes ________.

Precipitation: Precipitation near the equator ________,

Precipitation in high latitudes ________.

Latitudinal factors are the basic factors that shape climate.

Why does the phenomenon of "wearing fur coats in the morning and wearing gauze in the afternoon, holding the stove and eating watermelon at night" in the Turpan Basin of Xinjiang, my country?

Answer: Because the Turpan Basin has a lot of sand, gravel, soil and little water. The specific heat capacity of these substances is small. When the sun shines, their temperature rises quickly; when the sun sets, the temperature drops quickly, so the temperature difference between morning and evening is large.

According to relevant experts' predictions, after the Three Gorges Hydropower Station, my country's largest hydropower station, is fully completed, the temperature in the Three Gorges reservoir area will be affected to a certain extent: it will drop by about 2°C in summer and rise by about 2°C in winter. Why?

Answer: This is because the water in the reservoir area has a large specific heat. It heats up slowly in summer and cools down slowly in winter, so the temperature changes are small.

Sea and land factors:

Temperature:

1. At the same latitude, the land temperature in summer is higher than that of the ocean; the ocean temperature in winter is higher than that of the land.

2. Affected by warm and humid airflow, the temperature difference along the coast is small and the temperature difference inland is large.

precipitation:

Water vapor on land mainly comes from the ocean, with more precipitation along the coast and less precipitation inland (except for the west coast of the Tropic of Cancer).

Collaborative discussion:

①When you climb a mountain, do you notice any difference in the vegetation on the shady slopes and the sunny slopes? Why?

② Picture reading and analysis: What are the differences between the landscapes on the east and west sides of the Andes? Why?

Terrain factors:

Temperature:

The temperature at high altitude is ______, and the temperature at low altitude is ______.

precipitation:

Precipitation on windward slopes is ______, and precipitation on leeward slopes is ______.

Human activities can also affect climate

1. Beneficial partial climate improvement: artificial greening, water conservancy construction, and ecological protection forest construction;

2. It may be due to the deterioration of the local climate: indiscriminate cultivation, overgrazing, etc.;

3. It may worsen the global climate: global warming and ozone layer hole.
