Viticulture: Wind Patterns & Weather systems Flashcards
How does the Coriolis force effect wind patterns?
Wind systems in the Norhtern Hemisphere move around high pressure in a clockwise motion (S-N & W-E)
Wind systems in the Southern Hemisphere move around high pressure in a counterclockwise motion (N-S & E-W)
