Module 8 Flashcards
Climate
The average weather that occurs in a given region over a long period of time
Convection cell
Warm material rises, cold material sinks
Coriolis effect
Causes winds to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere
Hadley Cell
A convention current in the atmosphere that cycles between the equator and 30 degrees north and 30 degrees south
Polar cell
A convection current in the atmosphere, formed by air that rises at 60 degrees north and 60 degrees south and sinks at the poles, 90 degrees north and 90 degrees south
Ferrell cell
Convection current in the atmosphere that lies between Hadley and polar cells
Gyres
A large-scale pattern of water circulation that moves clockwise in the Northern hemisphere and counterclockwise in the Southern Hemisphere
Thermohaline circulation
Differences in water temperature
Upwelling
Movement of nutrient-rich bottom water to the oceans surface
El Niño
A reversal wind and water current in the South Pacific
La Niña
Helps to cool costal surface water and restore upwelling events
Rain shadow effect
A region with dry conditions found on the leeward side of mountain range as a result of hiking winds from the ocean causing precipitation on the windward side
Greenhouse effect
Absorption of infrared radiation by the atmospheric gases and reradiation of the energy back toward earth
