Wind Study Guide


After the "Wind" lecture and readings you should be able to answer and discuss the following questions.

What is wind?

How does wind differ from updrafts and downdrafts?

How does air move with respect to pressure?

What is the relationship between wind speed and pressure gradient?

What are the causes of unequal pressure at the Earth's surface? (note: there is more than one cause)

Describe the development of sea breezes during the day in terms of pressure, heating and air movement.

Describe the development of sea breezes at night in terms of pressure, heating and air movement.

How do the development of sea breezes related to the four thermal properties of water vs. land that were discussed earlier?

What are the two measurements that are needed to describe air movement?

Define air speed and the various units of measurement that are used.

Define wind direction.

Name the instruments that are used to measure air speed and wind direction.

What is the Coriolis Effect?

How is apparent motion affected for free moving objects in the Northern Hemisphere?

How is apparent motion affected for free moving objects in the Southern Hemisphere?

How is apparent motion affected for free moving objects at the Equator?
