Document Summary
Why does lifting create a cloud: lapse rate: rate of change in temperature observed while moving upwards through the. If lapse rate is 6 degrees per km, that means the temperature decreases by 6 degree for every km that we go up. Units: c/km or k/km: 3 basic principles: Latent heat release: heat absorbed or released associated with phase changes of water, ex. Liquid => solid (exothermic reactions-release heat to atmosphere) What are the processes that can cause a change in energy: radiation. Exothermic reaction-combustion: condensation releases the latent energy and turns it into sensible heating. Gas => liquid => solid =exothermic (adds heat to the atmosphere: to go from water (high energy state) to ice (low energy state), energy must be removed from system, goes out of water and into atmosphere. Solid => liquid => gas = removes heat from atmosphere: melting actually cools the atmosphere, conduction or contact with a hot surface.
