Description

"Changes and Distribution of Precipitation" Weather and Climate PPT Courseware 2

Undergraduate goals

Be able to read the world precipitation distribution map and summarize the characteristics of world precipitation distribution.

Distribution of precipitation

Isoprecipitation line

think about it

How are contours and isotherms defined?

The line connecting points with the same amount of precipitation at the same time is called a constant precipitation line.

Keywords: precipitation distribution

1. Around the world, some places have more precipitation and some places have less precipitation. Usually __________ is used to represent the distribution of precipitation. On the same precipitation line, the precipitation at each point is _____.

Extreme values ​​of precipitation in the world and China

World Cherrapunji, India Atacama Desert, Chile

China Taiwan Huoshaoliao more than 8000 mm Xinjiang Toksun 59 mm

Distribution of annual precipitation in the world

1. How many millimeters does the annual precipitation in places near the equator mostly exceed?

The annual precipitation in the polar regions is mostly below how many millimeters?

Equatorial region > 1000mm; polar regions < 500mm

2. Approximately how many millimeters of annual precipitation is there on the east coast of the continent near the Tropics of Cancer? What is the annual precipitation in millimeters on the west coast of the continent?

East bank >1000mm; West bank <200mm

The distribution pattern of annual precipitation in the world—“four more and four less”

(1) There is more precipitation near the equator; there is less precipitation in the polar regions.

(2) On both sides of the Tropic of Cancer, the east coast of the mainland has more precipitation, while the west coast of the mainland has less precipitation.

(3) In mid-latitude areas, coastal areas receive more precipitation and inland areas receive less precipitation.

(4) There is more precipitation on the windward slopes of mountains and less precipitation on the leeward slopes.
