Interannual Variations of Arctic Cloud Types in Relation to Sea Ice
Publisher: American Meteorological Society
Abstract: 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 ...
Arctic Cloud Changes from Surface and Satellite Observations
Publisher: American Meteorological Society
Abstract: Visual cloud reports from land and ocean regions of the Arctic are analyzed for total cloud cover. Trends and interannual variations in surface cloud data are compared to those obtained from Advanced Very High Resolution ...
Diurnal Cycles of Cumulus, Cumulonimbus, Stratus, Stratocumulus, and Fog from Surface Observations over Land and Ocean
Publisher: American Meteorological Society
Abstract: worldwide climatology of the diurnal cycles of low clouds is obtained from surface observations made eight or four times daily at 3- or 6-h intervals from weather stations and ships. Harmonic fits to the daily cycle are ...
A 39-Yr Survey of Cloud Changes from Land Stations Worldwide 1971–2009: Long-Term Trends, Relation to Aerosols, and Expansion of the Tropical Belt
Publisher: American Meteorological Society
Abstract: n archive of land-based, surface-observed cloud reports has been updated and now spans 39 years from 1971 through 2009. Cloud-type information at weather stations is available in individual reports or in long-term, seasonal, ...
Effect of Snow Grain Shape on Snow Albedo
Publisher: American Meteorological Society
Abstract: adiative transfer models of snow albedo have usually assumed a spherical shape for the snow grains, using Mie theory to compute single-scattering properties. The scattering by more realistic nonspherical snow grains is ...
A Model for the Spectral Albedo of Snow. II: Snow Containing Atmospheric Aerosols
Publisher: American Meteorological Society
Abstract: Small highly absorbing particles, present in concentrations of only 1 part per million by weight (ppmw) or less, can lower snow albedo in the visible by 5?15% from the high values (96?99%) predicted for pure snow in Part ...
A Model for the Spectral Albedo of Snow. I: Pure Snow
Publisher: American Meteorological Society
Abstract: We present a method for calculating the spectral albedo of snow which can be used at any wavelength in the solar spectrum and which accounts for diffusely or directly incident radiation at any zenith angle. For deep snow, ...
“Parameterization of Outgoing Infrared Radiation Derived from Detailed Radiative Calculations”
Publisher: American Meteorological Society
Abstract: Correction to Volume 39, Issue 12, Article 2667.
