ESCI 1012 Lecture Notes - Lecture 20: Lovettsville Air Disaster, Cumulonimbus Cloud, Thunderstorm
Document Summary
To start, we need to begin with thunderstorms. It takes a tre(cid:289)e(cid:290)dous a(cid:289)ou(cid:290)t of heat to co(cid:290)(cid:362)ert (cid:363)ater to (cid:362)apor due to (cid:363)ater"s large heat capacity. As vapor reverts to liquid, that heat is released into surrounding air, heat being moved around inside the air. As late as the end of wwii we still did not know how thunderstorms formed. It was not until the rise of civilian air traffic after wwii that we finally began to understand thunderstorms. Crashed 23 minutes after takeoff in a thunderstorm. Killed 21 passengers and crew of four. As wwii wound down, p-6(cid:799)"s drafted to study thu(cid:290)derstor(cid:289)s. Pilots flew through storms with minimal controls, let storm batter plane while cameras recorded instrument panel. They repeated this process over 1300 times. As warm, moist air rises into colder it"s warm vapor condenses and releases latent heat into the surrounding air. If updrafts raise air high enough, cumulonimbus clouds form and water can freeze.
