Module 3. Vertical Cross Sections at 32.5° S

a) Equivalent potential temperature and zonal wind

Questions

- Do the isentropes show a stable layer near the mountain top upstream?
- What is the stability like on the lee side?
- Can you locate the area of maximum zonal wind?

b) Divergence

Question

- Where are the convergence areas (at high and low levels) during Zonda?

c) Vertical velocity

Question

- Match the vertical velocity with the areas of convergence and divergence.

d) Relative humidity

Questions

- When does the dry layer on the lee side start forming?
- When does the humid layer on the windward side start forming?
