Cirrus cloud tropopause prevents the warm, moist air forming the thunderstorm from rising any higher, thus creating the flat top. In the tropics, these thunderstorms occasionally produce copious amounts of cirrus from their anvils. High-altitude winds commonly push this dense mat out into an anvil shape that stretches downwind as much as several kilometers. Individual cirrus cloud formations can be the remnants of anvil clouds formed by thunderstorms. In the dissipating stage of a cumulonimbus cloud, when the normal column rising up to the anvil has evaporated or dissipated, the mat of cirrus in the anvil is all that is left. Contrails
Cloud gaming Cloud gaming Cloud gaming, sometimes called gaming on demand, is a type of online gaming. Currently there are two main types of cloud gaming: cloud gaming based on "video" streaming and cloud gaming based on "file" streaming. Cloud gaming aims to provide end users frictionless and direct play-ability of games across various devices. In 2000, G-cluster demonstrated cloud gaming technology at E3. The original offering was cloud gaming service over Wi-Fi to handheld devices. Video game developer Crytek began research on a cloud gaming system in 2005 for "Crysis", but halted development in 2007 to wait until the infrastructure and
