Weather Patterns Flashcards
Convection currents
The current rising and falling creating winds
Sea breeze
A wind only happening at day, the warm air over land rises and gets replaced by cool air over sea, and then goes over sea and cools to replace warm air over land that rose
Land breeze
A wind only happening at night, the warm air over sea rises to be replaced by the cool air from over land and then traveled over land and cools, to replace cool air that moved to replace the warm air over sea
