1. Vertical Structure and the Thermal Wind
Reading, Ch. 12 of N-G Online
Wallace and Hobbs 7.2.7

2. Where you heat matters
Impacts of heating on stability in trop vs. strat

4. Stability and Isentropes
What is the impact of the large changes in the stratosphere?

5. Shear (note: not Sheer)
Two kinds of vertical shear
Examples (board)
Vertical shear of geostrophic wind has a special name _______________________
Note that difference shear has the units of velocity (you have not divided by the vertical distance). Derivative forms of shear are divided by the vertical interval when doing finite differencing.

6. 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!

7. Thermal Wind Example

8. 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?

9. Which is it?
