Week 4: 14 Sept
Monday - Tuesday
Problem 1.21 analysis and discuss the averaged hemispherical pressure from the homework page.
Whiteboard notes pg1, pg2, and pg3.
Discuss Homework 3. Everyone choose a sounding from a different month.
Install the Anaconda/Python interpreter for the HW3 script.
To create a recent model sounding using HRRR, start at the Continental US scale and click on any point. This will bring up a sounding. Choose on where radar indicates active precipitation, and compare with another elsewhere. Notice the Dendrite Grow Zone (DGR) elevations and associated temperatures.
Week 3: 8 Sept
Thursday
Talk about HW2 South Pole lapse rate and sea level equivalent pressure changes in summer and winter.
Fire field project description (Eliza).
Problem 1.21 analysis and discuss the averaged hemispherical pressure from the homework page.
Grand Junction Colorado example of a lifted air parcel from the averaged 50 mb from the surface mixing ratio and potential temperature (image). Excel analysis to get lifted air parcel starting point for LCL and CAPE.
Surface layer, near-surface friction to air motion over water and land, dependence on turbulent boundary layer, and finally, above, geostrophic flow is possible.
Tuesday and Wednesday
Presentations continue for HW1.
Week 2: 31 August
Thursday
Start presentations for HW1.
Tuesday and Wednesday
Discuss the free atmosphere and planetary boundary layer from the Monday soundings. Work towards HW 2.
Monday
Discuss dry adiabats: from PVγ = constant for a gas at pressure P and Volume undergoing an adiabatic process to potential temperature. Dry adiabats on the SkewT diagram.
Reno sounding from yesterday afternoon and this morning.
Bring questions to class on HW 1.
How to read skewT ln P diagrams. (local backup).
Overview Presentation: Work towards HW 2.
Stationary lee wave clouds downwind of the Sierra Nevada mountains.
Week 1: 24 August
Tuesday - Thursday
Work on HW 1.
Overview Presentation: Note the large hail in South Dakota, and thus the need to work on hail suppression.
Stationary lee wave clouds downwind of the Sierra Nevada mountains.
How to read skewT ln P diagrams. (local backup).
Do a Convective Condensation Level example for how much heating the atmosphere must have to get a pyrocumulus cloud associated with wild fires (CCL).
MODIS imagery from August 19th 2020 (fire detection and vast amounts of smoke).
NOTE: SkewT ln P images can be obtained from:

Monday
Outcome: Student introductions, syllabus, homework discussion, and started discussion of Atmospheric Physics, especially fires, smoke and clouds.
Thanks for the questions 😀 I appreciate them immensely!
