PPT-Clouds and Precipitation

Cloud Naming Prefix indicates height Cirro high 513 km Alto middle 25 km none low 02 km Name for appearance Cirrus wispy strands Stratus layered uniform Cumulus puffy with vertical structure. Water is ALWAYS in the atmosphere!. Earth’s water is mostly found in the oceans, but it is also found in lakes, rivers, ice sheets, in plants, and underground.. It can be present as a solid (like snow), liquid (rain), or gas (water vapor). . Two key impacts. Cloud feedback. Response of clouds to increased CO. 2. Aerosol indirect effects (AIEs). Response of clouds to changes in aerosol particles. Cloud feedbacks. Uncertainty in cloud feedbacks is main source of uncertainty in climate sensitivity. rainrate. increases. Kubar. , T., D. L.

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.. Deliberate Cloud Seeding. Cloud Seeding. Deliberate cloud seeding, with the goal of increasing precipitation by the injection of specific types of particles into clouds, has been pursued for over 60 years. . MSI-CIEC All Hands Meeting.

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.. Convectional Precipitation. Chapter 7. Weather and Climate. Objectives. Explore how the water cycle drives weather.. Discuss the conditions that favor thunderstorms and tornadoes.. Main Idea. Water vapor and changes in temperature are important factors in cloud formation and in precipitation.. 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 .
