Understanding Rainfall Patterns

The video discusses climate variability, comparing dry and wet regions like Panama. It explains factors affecting precipitation, such as prevailing winds and topography. Prevailing winds, which blow predominantly in one direction, can influence the leaning of trees. Winds crossing water bodies pick up moisture, leading to precipitation when they reach land, especially causing snow in winter.

Which region is described as having less than 30 centimeters of rain annually?

• A very dry place

• A coastal city

• A tropical rainforest

• A mountainous region

What is a characteristic of prevailing winds?

• They only occur in coastal areas

• They are always warm

• They blow predominantly in one direction

• They change direction frequently

How do prevailing winds affect trees over time?

• They cause trees to grow taller

• They make trees lean in the direction of the wind

• They have no effect on trees

• They cause trees to lose leaves

What happens when winds blow across large bodies of water?

• They lose moisture

• They pick up moisture

• They become colder

• They slow down

What is the result of winds reaching landfall in winter?

• Drought conditions

• Large amounts of snow

• Heavy rainfall

• Increased temperatures
