Interannual Variations of Arctic Cloud Types in Relation to Sea Ice
Sea ice extent and thickness may be affected by cloud changes, and sea ice changes may in turn impart changes to cloud cover. Different types of clouds have different effects on sea ice. Visual cloud reports from land and ocean regions of the Arctic are analyzed here for interannual variations of total cloud cover and nine cloud types, and their relation to sea ice. Over the high Arctic, cloud ...
متن کاملCovariance between Arctic sea ice and clouds within atmospheric state regimes at the satellite footprint level
Understanding the cloud response to sea ice change is necessary for modeling Arctic climate. Previous work has primarily addressed this problem from the interannual variability perspective. This paper provides a refined perspective of sea ice-cloud relationship in the Arctic using a satellite footprint-level quantification of the covariance between sea ice and Arctic low cloud properties from N...
متن کاملCirrus, contrails, and ice supersaturated regions in high pressure systems at northern mid latitudes
During the European heat wave summer 2003 with predominant high pressure conditions we performed a detailed study of upper tropospheric humidity and ice particles which yielded striking results concerning the occurrence of ice supersaturated regions (ISSR), cirrus, and contrails. Our study is based on lidar observations and meteorological data obtained at Lindenberg/Germany (52.2 N, 14.1 E) as ...
متن کاملThe effect of Arctic sea - ice extent on the absorbed ( net ) solar flux at the surface , based on ISCCP - D 2 cloud data for 1983 – 2007
We estimate the effect of the Arctic sea ice on the absorbed (net) solar flux using a radiative transfer model. Ice and cloud input data to the model come from satellite observations, processed by the International Satellite Cloud Climatology Project (ISCCP) and span the period July 1983– June 2007. The sea-ice effect on the solar radiation fluctuates seasonally with the solar flux and decrease...
متن کاملSensitivity of CAM5-Simulated Arctic Clouds and Radiation to Ice Nucleation Parameterization
Sensitivity of Arctic clouds and radiation in the Community Atmospheric Model, version 5, to the ice nucleation process is examined by testing a new physically based ice nucleation scheme that links the variation of ice nuclei (IN) number concentration to aerosol properties. The default scheme parameterizes the IN concentration simply as a function of ice supersaturation. The new scheme leads t...
