The Coriolis Effect and Geostrophic Motion - on a rotating planet winds get deflected off to the side, and how that leads to the wind above the boundary layer circling around high and low pressures
Atmospheric Circulation – Part One - Geopotential Height and “Meridional Winds” (N-S winds)
Atmospheric Circulation – Part Two – Thermal Wind - How the N-S winds combined with the Coriolis force causes the “thermal wind”, where zonal winds (W-E winds) increase with height
Atmospheric Circulation – Part Three – Instability - How angular momentum implies ever increasing W-E winds and destabilizes an equator – pole overturning cell, instead creating the Hadley cell that goes from the equator only to 30°N and 30°
And some background useful for understanding Atmospheric Circulation..
