ATOC 1050 Homework #2, page 1. Your Name: GRADE: ATOC 1050-1 Homework Assignment #2. Plotting and interpreting soundings, weather maps, and satellite images. Radar, Radiosonde soundings, stability, and Upper Air charts Due Tuesday, February 26, 2008, at the beginning of class. This assignment draws on material covered in the first 4 weeks of class, and in the textbook "Severe and Hazardous Weather", Chapters 1, 2, 3, and 5. The aim of this assignment is to give you some experience with using and creating graphs, tables, and maps, to familiarize you with some of the strange symbols and codes we use on weather maps, and to show you how to interpret weather balloon soundings and satellite images. You’ll also learn how radiosonde soundings are used for predicting the weather, how to read and interpret upper air charts, and estimate rainfall from radar images. This assignment will help prepare you for Homework #3, in which you will explore weather maps and forecasting in more detail. After it is graded, keep this assignment for future reference. You will need to go to the ATOC 1050 web site[ http://wxpaos09.colorado.edu/atoc1050 ] for the charts and data you will be working with. On the web site, go to the “Homework #2” link and download the data, charts, and images you’ll need. Check List – you must turn in the following in the proper order (Stapled together, with your name at the top of each sheet): 1. These seven pages of the assignment with questions 1 through 9 completely filled out. Please write neatly when completing this assignment – if we can’t read your answer you will not get credit for it. When printing these out, adjust your margins so the pages format properly (0.5-inch margins on both sides and top and bottom should work best). 3. The contoured maps of temperature and pressure (Question 4). 2. The “Stuve” plot of upper air data (Question 8) 4. You do not need to print out or turn in the weather maps, satellite images, radar images, or radiosonde soundings. 1. Weather Station data plot. Some day soon, Denver might report the following weather conditions: Temperature: 53 F Dew Point: 48 F Pressure: 1012.3 millibars Wind: 25 knots from the east Cloud cover: 8 Eighths (overcast) Weather: Moderate rain Using the descriptions and symbols provided in the text (pages 15 and 46), plot this data as it would appear on a weather map in the box to the right. The circle in the box represents the location of Denver on the weather map. The barometric pressure is indicated by the last three digits of the pressure, with the decimal point removed. Don’t worry about the pressure tendency. O 2. Surface Weather Maps Look at the station data plotted on the Surface Weather map on the web site. For the four cities listed in the table, fill in the observations of temperature. To convert the three-digit pressure code to an actual pressure, in millibars, do the following: If the pressure code XYZ is less than 500, then the pressure is
