Abovce the Clouds: A Berkeley View of Cloud Computing (Feb. 2009). Definitions (I). Cloud Computing refers to both the applications delivered as services over the Internet and the scalable hardware and systems software that provide those services. . 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. What is a cloud?. A cloud is a group of water droplets in the atmosphere.. The water vapor condenses during the water cycle to form clouds.. Cirrus Clouds. They are the highest clouds.. They look thin, wispy, or feathery.. Cumulus Clouds. Stratocumulus. Layered but puffy clouds at lower to mid elevations. Cumulus Clouds. Altocumulus. Thick puffy clouds that can be found at middle elevations. Cumulus Clouds. Cirrocumulus. HPC(Exascale) . Systems.
