WebSep 1, 2006 · Riemer and Wexler (2005, henceforth RW05) have utilized the turbulent collision kernel model of Zhou et al. (2001) to study the effect of turbulence on the initiation and development of raindrops from cloud droplets. They concluded that, for a cloud dissipation rate at 300 cm 2 s −3, turbulent coagulation can move 96% of the droplet … WebSep 1, 1998 · The graupel particle diameter reaches 6 mm in 8 min under the dissipation rate of 400 cm 2 s −3 and in 6 min under the dissipation rate of 800 cm 2 s −3. Because the fast growth of graupel was observed in a mature stage cumulus clouds, the values of the dissipation rate of 800 cm 2 s −3 seem to be reasonable, and even higher …

Thunderstorms. Two characteristics of thunderstorms make them an important element in fire weather. The first is the fire-starting potential caused by lightning strikes from cloud-to-ground. The second is the thunderstorm downdraft which spreads out upon nearing the ground, producing strong, shifting, and gusty winds for a short time. WebClouds are composed of liquid suspended water droplets in about a 100% RH environment. The three primary ways that clouds dissipate is by (1) the temperature increasing, (2) the cloud mixing with drier air, or (3) the air sinking within the cloud. ... unsaturated air cools at the dry adiabatic lapse rate when rising and warms at the same rate ... clp126
