| Description: Adiabatic temperature changes occur when Air is compressed Motion of air molecules increases Air will warm Descending air is compressed due to increasing air pressure Air expands Air will cool Rising air will expand due to decreasing air pressure Adiabatic rates Dry adiabatic rate Unsaturated air Rising air expands and cools at 1° C per 100 meters (5.5° F per 1000 feet) Descending air is compressed and warms at 1° C per 100 meters Wet adiabatic rate Commences at condensation level Air has reached the dew point Condensation is occurring and latent heat is being liberated Heat released by the condensing water reduces the rate of cooling Rate varies from 0.5° C to 0.9° C per 100 meters Picture Stats: Views: 265 Filesize: 891.27kB Height: 921 Width: 1358 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=39788 |
