Changes and differences in precipitation PPT, Part 3: Seasonal changes in precipitation

1. Precipitation is different in different places at the same time.

2. The same place has different precipitation in different seasons.

3. Precipitation histograms are commonly used to represent seasonal changes in precipitation.

Interpretation of precipitation histograms

Which month has the most precipitation and the least precipitation, and how much is each?

Is precipitation distributed evenly throughout the seasons?

Changes and Differences in Precipitation PPT, Part 4: The Law of “Four More and Four Less”

1. There is __ precipitation in the areas near the equator and __ precipitation in the polar regions.

Latitudinal factors: more precipitation in the equatorial regions and less precipitation in the polar regions

2. Near the Tropic of Cancer, precipitation is __ on the east coast of the mainland and __ on the west coast.

3. In mid-latitude areas, precipitation is __ in coastal areas and __ in inland areas.

Observe and think

The areas with the most and least precipitation in the world?

Near the Tropic of Cancer, what are the precipitation characteristics on the east and west coasts of the mainland?

What are the characteristics of annual precipitation in mid-latitudes, coastal and inland areas?
