"Climate and Factors Affecting Climate" PPT

Part One: Knowledge Review

1. Weather refers to ___________, near the earth in a short period of time,

___________ of humidity, air pressure and other factors.

Wind, rain, etc. are all ___________.

2. Weather is composed of many elements, among which the main ones are ___________, ___________, wind, etc.

Among them, ___________ is the basic element that makes up the weather.

Climate: refers to the weather characteristics of a certain area over a long period of time, including average and extreme weather conditions.

Mainly described by factors such as temperature and precipitation

Discussion: Which months in your hometown have higher temperatures, which months have lower temperatures, which months have more precipitation, and which months have less precipitation?

Climate and factors affecting climate PPT, Part 2: The impact of latitude and location on climate

(basic factors)

Areas with different latitudes receive different amounts of heat from solar radiation, and are located in different temperature zones on the earth.

(1) Latitude position mainly affects temperature

(2) The temperature in low latitudes is higher and the temperature in high latitudes is lower

Climate and factors affecting climate PPT, Part 3: Effects of land and sea properties on temperature and precipitation

Specific heat (C): The heat absorbed by a unit mass of a certain substance when its temperature rises by 1°C is called the specific heat of the substance.

Unit of specific heat: J/(kg·℃)

The specific heat of water is 4.2×103 J/(kg · ℃)

Its physical meaning is: the temperature of one kilogram of water per

To increase (decrease) 1℃, the heat absorbed (or released) is 4.2×103J

【think】

Compare the specific heat of water and sand, and talk about the different impacts of ocean and land on climate?

Because the physical properties of land and ocean are different, land has a smaller specific heat, warms up quickly, and cools down quickly. On the contrary, the ocean has a large specific heat, warms up slowly, and cools down slowly.

Therefore, in the same latitude zone, the land temperature is high in summer and the ocean temperature is low, and the opposite is true in winter.

The ocean causes less temperature variation in coastal areas.

Climate and factors affecting climate PPT, Part 4: The impact of terrain on climate

(1) As the altitude increases, the temperature decreases.

(2) In the troposphere, the temperature drops by about 6°C for every 1,000 meters the ground rises.

The warm and moist air encounters terrain obstruction on its way forward, and is forced to climb along the windward slope, and the airflow sinks on the leeward slope of the mountain.

Climate and factors affecting climate PPT, Part 5: Main factors affecting climate

(1) The influence of latitude on climate

Generally, temperatures are high in low latitudes and low in high latitudes.

(2) The impact of ocean and land properties on temperature and precipitation

In the same latitude zone, the land temperature is high and the ocean temperature is low in summer, and the opposite is true in winter.

The ocean causes small temperature changes and abundant precipitation in coastal areas.

(3) The impact of terrain on temperature and precipitation

1. As the altitude increases, the temperature decreases.

2. It rains more on the windward slope and less on the leeward slope.

Climate and factors affecting climate PPT, Part 6: Consolidation exercises

1.The main factors of climate differences between A and B_______________

2.C and D are also very different in climate. The main reason is___________

3.C increases or decreases temperature _____ more than D. Its annual difference and daily difference are ___ higher than D.

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 Turpan Basin in my country?

Answer: Because there are a lot of sand, gravel and soil in the Turpan Basin, the specific heat capacity of these materials 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.
