PPT-Milltown’s Water Droplets

Take the Challenge Have you been really thirsty in the last 24 hours Did you have a hard time getting something to drink Did you wonder if what you drank to quench your thirst was going to make you sick. Droplets over 150 microns in size resist evaporation much more than smaller droplets because of their large surface area Therefore the potential for drift rapidly decreases when the diameter of droplets is increased to about 150 microns A range of s Sweden.

Forms of Condensation . and Precipitation. Notes. Cumulonimbus Cloud. Cloud Formation. Clouds. – visible aggregate of minute droplets of water, or tiny crystals of ice, or a mixture of both.. Clouds are a form of condensation produced when water vapor condenses in the atmosphere. The cloud formation process includes adiabatic cooling, and condensation of water vapor as a parcel of air rises above the lifting condensation level.. The water cycle: is there a beginning?. The water cycle: PRECIPITATION. The process in which water (rain, sleet, snow or hail) falls from clouds in the sky. Effects: . too much causes flooding. Storms cause damage to vegetation, structures. Cloud and Aerosol Physics. Goals:. Understand . …. H. omogeneous and heterogeneous nucleation of cloud droplets.
