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..
Density, Stability and Motion in Fluids – some basics about instability
Potential Temperature – explaining “potential temperature” and why the “potential temperature” increases with altitude
Temperature Profile in the Atmosphere – The Lapse Rate – Lots more about the temperature profile in the atmosphere
Good afternoon,
Thank you very much your blog, I recently discovered it through Climate etc, I really appreciate your approach & humoristics notes. Quite refreshing.
Regarding global circulation, I will follow your advise and order books you are recommending. I recently purchased « Dynamic Analysis of Weather and Climate: Atmospheric Circulation, Perturbations, Climatic Evolution » from Dr Leroux and I am really interesting in his concept of Mobil Polar High, I would like to know if you were familar with it and if so what would be your comments, critiques?
Nicolas,
Thanks for your kind comments.
I haven’t seen this book and don’t know about his concept.
