RISLow Cloud Type over the Ocean from Surface Observations. Part I: Relationship to Surface Meteorology and the Vertical Distribution of Temperature and Moisture
Publisher: American Meteorological Society
Abstract: Surface cloud observations and coincident surface meteorological observations and soundings from five ocean weather stations are used to establish representative relationships between low cloud type and marine boundary ...
On Trends and Possible Artifacts in Global Ocean Cloud Cover between 1952 and 1995
Publisher: American Meteorological Society
Abstract: Synoptic surface cloud observations are used to examine interdecadal variability in global ocean cloud cover between 1952 and 1995. Global mean total cloud cover over the ocean is observed to increase by 1.9% (sky cover) ...
Interannual and Interdecadal Variability in the Storm Track, Cloudiness, and Sea Surface Temperature over the Summertime North Pacific
Publisher: American Meteorological Society
Abstract: Interannual and interdecadal variability in the summertime mean North Pacific storm track is examined in relation to summertime mean sea surface temperature (SST), nimbostratus, and marine stratiform cloudiness (MSC) ...
Low Cloud Type over the Ocean from Surface Observations. Part II: Geographical and Seasonal Variations
Publisher: American Meteorological Society
Abstract: Synoptic surface cloud observations primarily made by volunteer observing ships are used to construct global climatologies of the frequency of occurrence of individual low cloud types over the ocean for daytime during ...
Assessing the Impact of Meteorological History on Subtropical Cloud Fraction
Publisher: American Meteorological Society
Abstract: This study presents findings from the application of a new Lagrangian method used to evaluate the meteorological sensitivities of subtropical clouds in the northeast Atlantic. Parcel back trajectories are used to account ...
interannual Variability in Stratiform Cloudiness and Sea Surface Temperature
Publisher: American Meteorological Society
Abstract: Marine stratiform cloudiness (MSC) (stratus, stratocumulus, and fog) is widespread over subtropical oceans west of the continents and over midlatitude oceans during summer, the season when MSC has maximum influence on ...
Observational Evidence That Enhanced Subsidence Reduces Subtropical Marine Boundary Layer Cloudiness
Publisher: American Meteorological Society
Abstract: onventional wisdom suggests that subsidence favors the presence of marine stratus and stratocumulus because regions of enhanced boundary layer cloudiness are observed to climatologically co-occur with regions of enhanced ...
Improved Techniques for Evaluating GCM Cloudiness Applied to the NCAR CCM3
Publisher: American Meteorological Society
Abstract: Evaluations of GCM cloudiness typically compare climatological output with observations, but averaging over time can obscure the presence of compensating errors. A more informative and stringent evaluation can be obtained ...
Empirical Removal of Artifacts from the ISCCP and PATMOS-x Satellite Cloud Records
Publisher: American Meteorological Society
Abstract: he International Satellite Cloud Climatology Project (ISCCP) dataset and the Pathfinder Atmospheres?Extended (PATMOS-x) dataset are two commonly used multidecadal satellite cloud records. Because they are constructed from ...
