Vertical Structure and the Thermal Wind
Reading, Ch. 12 of N-G Online Wallace and Hobbs 7.2.7
Where you heat mattersImpacts of heating
on stability in trop vs. strat
Stability and Isentropes
Shear (note: not Sheer)
Two kinds of vertical shear Examples (board)
Vertical shear of geostrophic wind has a special name _______________________
Thermal Wind Equation Take vertical derivative of Vg, use hypsometric (see
derivation in text) The link between pressure/height/wind and temperature. Doesn't “blow”, but if it did, it would with colder
temperatures (smaller thicknesses) to left, and harder with more temperature contrast!
Explains a lot, like the existence of the polar jet!
Thermal Wind Example
Cold and Warm Core
Thought Experiment, Low center which gets more intense with height (stronger winds)
Multi Color Dry Erase How about the reverse? What is this example of?
Which is it?
