Analyze the winds! Use the wind animation virtual globe: https://earth.nullschool.net Here, you may move around the planet, viewing winds at the surface, 500 mb elevation, or other levels. You may overlay mean sea level pressure (MSLP), temperature, or other things. You may change the date (look next to Now, select calendar symbol). Under Mode, remain in "Air" Your goal is to identify features of atmospheric circulation, and describe why they are there. Take any four features of atmospheric circulation, and try to find excellent examples of them on the globe. Choose temperature and air pressure overlays to help you explain the wind patterns. Criteria (for full credit): 1. Mentions the correct global circulation feature (and it is clearly indicated on the screenshot image). Use features mentioned in Fig. 3.14, or in the text under Fig. 3.15 on the last p of page reading in the Module. Some features are the ITCZ, subtropical high pressure systems, etc. In a caption below each screen shot, provide the date, time, location, and what is being shown in the screen shot. 2. What is the pressure gradient causing the winds? 3. For at least one of your four screenshots, describe the effect of the Coriolis forces affecting wind direction. 4. Any other observation, for example the role of the ocean vs land affecting temperature gradients. It is OK to have more than one screenshot per feature, for example, if you want to show winds with. temperature AND winds with pressure. Create a document with the screenshots and your explanations beneath the screen shots. If you use something other than Microsoft Word, please try to save it as a PDF file. Remember, you may choose a date in the winter, you may choose a specific weather event, and you may choose any level in the atmosphere (but there is not much presented on upper level winds thus far).
