An Investigation on the Climatic Effect of Contrail Cirrus

摘要: High cloud cover in the absence of middle and low clouds for Salt Lake City, Utah, during period 1949–1982 has been analyzed. A significant increase mean annual high is evident from 1965 to 1982, This appears coincide with anomalous jet aircraft traffic that period. Analysis surface temperature City shows a noticeable on basis 1965–1982. We have developed two-dimensional (2-D) cloud-climate model investigate perturbation fields. The consists 2-D climate formation are interactive through radiation program. covers budgets at top atmosphere computed present compare reasonably well observations, 5% uniform latitudes between 20° 70° N would produce an by about 1°K small variations across latitudes, positive feedback associated due enhanced infrared emission additional specific humidity produced model.
