ATMS 411 Homework [Main Page] [Daily Notes] [Final Project]

 

Homework style example.

ONLINE ASSIGNMENTS ARE GIVEN IN WEBCAMPUS.

TEAMS FOR HOMEWORK ASSIGNMENTS WHEN REQUIRED:
Flat Earth. (Jeremy, Jacob, Christopher)
SEA (Siying, Ethan, Andy)
Earth (us) Fire (California) and Water (Talia, Taylor, Zach)
No Team Name [aka NTM, Aunti M, Wizard of Oz] (Michael, Levi, Garrick, Melinda)
Unicorn (Paul, Thomas
, Aaron)

 

Homework 2.
Part 1. Students will present problems as assigned for their group and will turn in the assignment.
Part 2. Turn in problems of question 2 through web campus.
Parts 1 and 2 should be graded separately.

Read problem 3.18 . Then with these questions in mind, read chapter 3.

1. Present problem 3.18 . (overall we will look at questions b, c, d, e, f, g, h, i, j, l, m, n ,o, p, t, u, v, w)
Presentation Assignments (each person presents at least one problem).

b, c, q, w (Flat Earth)

d, e, f, r (SEA)

g, h, i, s (Earth Fire and Water)

j, l ,m, t, v (NTM)

n, o, p, u (Unicorn)

2. Do problems 3.20, 3.23, 3.26 (also discussed in class), 3.28.
(it will be helpful to read problems 3.21 and 3.22 before doing 3.23).

Note: On problem 3.28, if the energy release, 5x106 J/m2 is from the latent heat released in the formation of a liquid water cloud,
the cloud might have properties as follows: 100 m thick, 600 cloud droplets per cm3, 20 micron cloud radius, liquid water path 2 kg/m2,
since the latent heat release from cloud droplet condensation is 2.5x106 Joules/kg. For those interested, here's a journal article on cloud properties.
(From this information it is possible to calculate the cloud optical depth, albedo, and transmission).

Homework 1. Turn in this homework assignment through webCampus, using Microsoft Word.

Make one MSword document that has solutions for problems 1 through 3.

Read chapter 1.
1. Do problem 1.6. Write your answers into the first part of the MSword document you will be turning in for this assignment.

2. Do problem 1.12, being sure to express your answer in degree C per kilometer.
Then go to the South Pole and find a sounding that best resembles the features of this problem.
Include the SkewT LogP graph in your report and discuss it.

3. Prepare a short report that describes the atmosphere for 00Z, 9 January 2019 for these two locations, Rochambeau French Guiana (SOCA, Station 81405) and Barrow Alaska USA (PABR, Station 70026)
a. Use Google Earth to view these two locations, Rochambeau French Guiana and Barrow Alaska USA. Save images of each location and use as figures 1 and 2 in your report.
Include grid lines in these images so you can see the Tropic of Cancer and the Arctic Circle, respectively, and discuss the significance of these geographical demarcations,
both in of themselves and with respect to the amount of solar radiation expected to be seen seasonally in their vicinity.

b. Acquire the gif skew T soundings for PABR and SOCA for this day and time. Make these soundings figures 3 and 4 in your report. Discuss these soundings.
Observe the lapse rate Γ=-dT/dz from the slope of the temperature versus height graph and interpret.

c. Near equator: Rochambeau French Guiana (get sounding text for SOCA from the Wyoming site.
Plot pressure and temperature vs height as figure 5 in your report. Calculate density and plot versus height in a separate graph as figure 6).

d. Near north pole: Barrow Alaska (get sounding for PABR from the Wyoming site.
Overlay pressure and temperature vs height with the SOCA sounding in figure 5. Calculate density and overlay with the SOCA sounding in figure 6).

e. Then make a graph and fit a trendline for the natural logarithm of pressure, ln(Pressure) vs height to obtain the scale height of the atmosphere at these two locations, considering data to a height of 2 km as figure 7.

In your report, compare and contrast the difference in the meteorology between these two sites for 9 January 2019 as a function of height in the atmosphere, both near the surface and throughout the atmosphere.

NOTE: A short report should be written like a short section in a text book.
A. Title for the report. Your name.
B. First paragraph describes what's in the report, describes what is to be accomplished.
C. Each figure must have a number and a caption. Figures must be in publication format -- high quality figures with 16 point (or greater) bold black font; tick marks inside. All axes 1 point thick and black.
D. Each figure must be discussed in the text by number, describing the significance of the figure and its relationship to other figures as needed.
E. Any equations should be offset, as in a textbook, and each equation should have a number. Refer to equations by number. Use the equation editor in microsoft word to prepare your equations.
F. The last paragraph should summarize the overall outcome of the report.
Get started early.
Take advantage of the UNR writing center to have them read your report draft to give you feedback on writing quality.

TOOLS:
A. Meteorological data can be obtained from the University of Wyoming web site.
B. Most (or all) computers readily accessible to all students, using their netID, have Google Earth, MSword, and Excel.
C. You can use your netID to also access these software packages through the UNR remote services application.

 

 

FINAL PROJECT, START NOW!

Deliverables:
ATMS 411 in class presentation and turn in presentation here.
ATMS 611 in class presentation, report, and turn in presentation here.
Presentations are 5 to 10 minutes long.

Atmospheric Physics students take photographs of the atmosphere or environment, and explain the Atmospheric Physics connection.
For example, blue sky, sky polarization, coronas, halos, rainbows, lenticular clouds, gravity waves, lightning, water phase clouds, ice phase clouds,
inferring air motions and winds from cloud structures, contrails, vortices in contrails, sky color during pollution events, sky color near the horizon, sky color at sunset looking to the east.
Photographs of the dendritic nature of ice growing on windshields on cold days, the shape and nature of icicles, dew on a moist mornings are also possible topics.
Photographs of snow flakes and snow crystals, here's a discussion.
If you have special hobbies or work, like paragliding, Atmospheric Physics related aspects can be included in your project.
You can use soundings, satellite images, etc, to also help tell the story.

ATMS 411 students will do a presentation
ATMS 611 students will do a presentation and a report.

Resources that may help

Gravity wave discussion.
Snow crystal/flake observations.
Cloud identification.
NASA WorldView for satellite imagery. You can add layers for additional information.
National Weather Service balloon soundings, served by the Univ of Wyoming.
