Why is there a different wind and climate pattern in the northrn hemisphere than in the southern hemisphere?

Answer 1

Atmospheric circulation patterns are of critical importance in determining the climate of a location. On a global scale, atmospheric motions transport heat from the topics towards the poles. Evaporation over the oceans supplies the water molecules that support precipitation over land. These circulation patterns are in large part driven by energy differences between regions of the globe. As discussed in Chapter 7, dry climates are associated with the descending branch of the Hadley Cell while moist climates coincide with the ascending branch. On a regional scale, precipitation on the lee side of a mountain is typically less than on the windward side. On a still smaller scale, the amount of snow downwind of a snow fence is on average larger than the amount upwind.
