Using atmospheric data here we will study both the Hadley Cell in the tropics and the turbulent Eddy Circulation in the middle latitudes.
Hadley Cell – tropics
Relevant climatological fields can be plotted using the EsGlobe interface (use Climatologies/Atmosphere tab).
Plot zonally averaged fields of temperature, potential temperature, meridional wind , vertical wind and zonal wind and discuss evidence of the Hadley Circulation.
The relationship between horizontal temperature gradient and vertical wind shear is described here: Thermal wind.
A visualization of the Hadley Cell shifting between seasons can be found here: a-breathing-earth.
A summary of the Hadley Cell project can be found in Hadley Cell Virtual Lab (and accompanying paper: Virtually Enhanced Fluid Laboratories for Teaching Meteorology) .
