2qr. What atmospheric conditions are necessary for the development of ordinary cell (air mass) thunderstorms? Get solution
2qt. Sinking air warms, yet thunderstorm downdrafts are usually cold. Why? Get solution
3qr. Describe the stages of development of an ordinary cell (air mass) thunderstorm. Get solution
3qt. If you are confronted by a large tornado in an open field and there is no way that you can outrun it, your only recourse might be to run and lie down in a depression. If given the choice, when facing the tornado, would you run toward your left or toward your right as the tornado approaches? Explain your reasoning. Get solution
4qr. How do downdrafts form in ordinary cell thunderstorms? Get solution
4qt. Suppose while you are standing on a high mountain ridge a thundercloud passes overhead. What would be the wisest thing to do—stand upright? lie down? or crouch? Explain. Get solution
5qr. Why do ordinary cell thunderstorms most frequently form in the afternoon? Get solution
5qt. Tornadoes apparently form in the region of a strong updraft, yet they descend from the base of a cloud. Why? Get solution
6qr. Explain why ordinary cell thunderstorms tend to dissipate much sooner than multicell storms. Get solution
6qt. On a map of the United States, place the surface weather conditions (air masses, fronts, and so on) as well as weather conditions aloft (jet stream, and so on) that are necessary for the formation of most supercell thunderstorms. Get solution
7qr. How does the National Weather Service define a severe thunderstorm? Get solution
7qt. Suppose several of your friends went on a stormchasing adventure in the central United States. To help guide their chase, you stay behind, with an Internet-connected computer and a smart phone. Which current weather and forecast maps would you use to guide their storm chase? Explain why you choose those maps. Get solution
