Control of cloud droplet concentration in marine stratocumulus clouds. What is precipitation?. Water that falls from the sky, it can be in different forms.. Hail, sleet, snow, rain.. Rain. As warm air rises into the atmosphere it cools. The air creates water vapor which condenses and forms into clouds. Once the clouds are big enough and are holding enough water it begins to rain.. CBRFC Stakeholder Forum. July 31, 2012. PRECIPITATION DATA. – . WHY IS THIS IMPORTANT ?. Primary Impacts:. Immediate runoff from rainfall events. Affects soil moisture conditions and seasonal volume forecasts. Read and study each page of this PowerPoint with your table group.. Each group member should take notes about each type of precipitation. . You are looking for information that describes:. How the different types of precipitation form.

Water vapor in the atmosphere is visible as clouds and fog. . Water vapor collects with other materials, such as dust, in clouds. Precipitation condenses, or forms, around these tiny pieces of material, called cloud condensation nuclei (CCN).. Relief. There are three reasons why air is forced upward also forming three types of precipitation.. Relief . Precipitation- caused by winds carrying air up over a mountain barrier..

Acid precipitation. includes all forms of precipitation . (rain, sleet, snow. ). with a high concentration of acids present. . Acid precipitation forms when water vapor and droplets in the atmosphere combine with sulfuric and nitric oxides. This forms sulfuric and nitric acids, which have a lower pH than typical rainfall.. LECTURE 5. PRECIPITATION GAUGE NETWORK. To have an idea of areal distribution of precipitation there should be adequately planned rain gauge network. There are two reasons to plan a network:. Catch area of a precipitation gauge is very small. Artificial rain making.. Process of Precipitation:. Precipitation is caused by condensation of water . vapours. of the air mass. . The ascending air mass with sufficient amount of water . vapours. becomes saturated due to adiabatic cooling. Condensation of water .
