ATOC 1050 Homework #2, page 1. Your Name: GRADE: ATOC 1050-1 Homework Assignment #1. Plotting and interpreting soundings, weather maps, and satellite images. Radar, Radiosonde soundings, stability, and Upper Air charts Due Tuesday, September 23, 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://atoc.colorado.edu/wxlab/atoc1050 for the charts and data you will be working with. On the web site, go to the “Homework #1” 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 6). 2. The “Stuve” plot of upper air data (Question 8) 4. You do not need to print out or turn in the other weather maps, satellite images, radar images, or radiosonde soundings. 1. Radar images. You’ve heard about Doppler Rader and seen it on TV; now you’ll see what it really does. 1A. Look at the Radar Reflectivity image of Hurricane Dolly on the web site. The radar is located at Brownsville, Texas, located at the center of the image. The Hurricane is the swirl of green, yellow, and orange colored precipitation surrounding the eye, which appears blue in this image (and marked with the letter “e”). Using the color scale at the right of the image, what is the greatest radar reflectivity (in dBZ) in the rain clouds within the hurricane? Look at Fig 2.9 on page 29 of the text, and convert the dBZ reflectivity to a rainfall rate. Now, do the same for the light blue patches within the eye of the hurricane. dBZ values less than 20 indicate cloud, but no rain. Reflectivity (dBZ)
