Homework Exercise 11 Skew-T diagram practice
Due: Thursday, March 24th, 2022 @ 11:00 AM (test day!)

Answer the following questions based on the soundings provided.
You must complete 3 for normal homework and the remaining 3 are extra credit for 10 extra points.
For each sounding (please be organized and clear about which set of answers if for what sounding):

1. What is the surface temperature?
2. What is the temperature at 500 hPa?
3. What is the surface dewpoint temperature?
4. What is the dewpoint temperature at 500 hPa?
5. What is the mixing ratio at 700 hPa?
6. What is the saturation mixing ratio at 700 hPa?
7. What is the relative humidity at 700 hPa?
8. Do you see evidence on the sounding of stacked airmasses or upper-level fronts? If so, circle it.
9. What is the windspeed and direction at the surface?
10. What is the wind speed and direction at 300 hPa?
11. Is there evidence of low-level (consider below 700 hPa) wind shear? How do you know?
12. Are there clouds present?
13. What is the potential temperature at 800 hPa? (if you cannot find it on the sounding, calculate it)
14. What is the equivalent potential temperature at 950 hPa? (Skip if off the chart or above elevation)
15. At what pressure level is the tropopause?
16. At what pressure level would falling ice particles start to melt into rain?
17. Draw a parcel line from the surface.
18. Is there surface-based CAPE? If so, is there CIN?

Comparing soundings:

19. Which location has the highest vapor pressure at the surface?
20. Which has the highest RH at the surface?
21. Which location has the deepest layer of clouds?
22. Which location has the most CAPE?
23. If it were to precipitate at all locations, would any see snow?
24. Which location is at the highest elevation?
25. Which location is at the lowest elevation?
