Course Objectives		1.To provide the concepts of the physical processes in clouds. 2.To provide an ability to use the applications of the thermodynamics of the moist in the atmosphere. 3.To give an ability to define the microstructure of clouds and precipitation.
Course Description		Review of thermodynamics of water vapor. Clausius-Clapeyron equations for liquid to vapor, ice to vapor and ice to liquid water phase changes. Bergeron-Findeisen-Wegener theory of precipitation. Usage of the psychrometric chart. Droplet growth by diffusion-condensation. Solution and droplet curvature effects on saturated water vapor pressure. Raoults law, Kelvin and Köhler curves. Atmospheric condensation nuclei, Collision-Coalesence theory of precipitation formation. Precipitation types. Cloud and fog classifications. Cloud forecasting. Artificial cloud seeding and weather modification.
Course Outcomes		1. To be able to define atmospheric air composition and mixture of ideal gases and to be able to formulate the equation of ideal gas and Daltons law. 2. To be able to identify and analysis each term of the first law of thermodynamics according to sensible and latent heat. 3. To be able to identify state variables and exploit process in which improve according to increase altitude with using thermo-diagram. 4. To be able to select and utilize appropriate equations related to atmospheric water vapor. 5. To be able to identify humidity variables and phase change (mixing ratio, specific humidity, absolute humidity, relative humidity, virtual temperature, dew point temperature, potential temperature). 6. To be able to describe phase change for liquid to vapor, ice to vapor and ice to liquid water phase changes with using the Clausius-Clapeyron equation. 7. To be able to formulate process of reaching saturation for formation of clouds and fogs. 8. To be able to describe atmospheric static and dynamic stability and their effects to form clouds. 9. To be able to describe cloud classification, cloud development and forms, cloud and fog forecasting. To able to describe the Wegener-Bergeron-Findeisen process to form precipitation for cold clouds. 10. To able to describe process control the growth of precipitation: nucleation, diffusion, and collision for both liquid droplets and ice crystals. To able to describe the curvature effect from Köhler and Kelvin equations
