10 Questions
The equator ○ Due to the ITCZ
convergence
60 degrees S ○ Polar front - frontal lifting
convergence
A band extending from the subtropical east coast of continents to the east and poleward, ending around 60 degrees ○ Polar front + warm currents
convergence
Mountainous regions on the west coast of continents from 40 to 70 degrees latitude ○ Polar front + warm currents + orographic lifting (mountains)
convergence
You need 2 things to generate precip ○ Ample moisture (water vapor) in the atmosphere (relies on evap) ○ A reason for that moisture to leave (precip)
convergence
How does ample moisture enter the atmosphere to generate precipitation?
Water vapor enters the atmosphere via evaporation, with the main source of moisture being the oceans. The warmer the atmosphere, the more evaporation can occur.
What are the 4 main regions that receive adequate precipitation and the contributing factors?
- The equator - due to the ITCZ 2. 60 degrees S - polar front and frontal lifting 3. A band extending from the subtropical east coast of continents to the east and poleward, ending around 60 degrees - polar front and warm currents 4. Mountainous regions on the west coast of continents from 40 to 70 degrees latitude - polar front, warm currents, and orographic lifting (mountains)
What are the two things required to generate precipitation on a large scale?
Ample moisture (water vapor) in the atmosphere, which relies on evaporation, and a reason for that moisture to leave (precipitation).
Why do mid and high latitudes receive the heaviest precipitation events?
They receive the heaviest precipitation events when there is advection of moist, tropical air toward the poles, and the best way for moisture to leave and cool is to cool down the air.
What is the relationship between atmosphere temperature and evaporation?
The warmer the atmosphere, the more evaporation can occur.
Test your knowledge of the main regions where adequate precipitation occurs with this geography quiz. Explore the factors that contribute to rainfall in specific areas, including the influence of the ITCZ, polar fronts, warm currents, and mountainous regions.
