RISThe Excitation of Equatorial Waves by Deep Convection in the NCAR Community Climate Model (CCM3)
Publisher: American Meteorological Society
Abstract: The forcing of equatorial waves by convective heating in the National Center for Atmospheric Research Community Climate Model (CCM3) is investigated and compared with the forcing deduced from observations of convective ...
A Scatterometer Geophysical Model Function for Climate-Quality Winds: QuikSCAT Ku-2011
Publisher: American Meteorological Society
Abstract: pace-based observations of ocean surface winds have been available for more than 25 years. To combine the observations from multiple sensors into one record with the accuracy required for climate studies requires a consistent ...
Local Time- and Space Scales of Organized Tropical Deep Convection
Publisher: American Meteorological Society
Abstract: The time- and space scales of tropical deep convection are estimated via analysis of 3-hourly Global Cloud Imagery (GCI) data for 3 yr at 35?70-km resolution. The emphasis is on estimating local time- and space scales ...
Capability of the SMAP Mission to Measure Ocean Surface Winds in Storms
Publisher: American Meteorological Society
Abstract: he NASA Soil Moisture Active Passive Mission SMAP was launched in January 2015 and has been providing science data since April 2015. Though designed to measure soil moisture, the SMAP radiometer has an excellent capability ...
Validation of High Ocean Surface Winds from Satellites Using Oil Platform Anemometers
Publisher: American Meteorological Society
Abstract: AbstractReliable sources for validating wind observations made by spaceborne microwave radiometer and scatterometer sensors above 15 m s?1 are scarce. Anemometers mounted on oil platforms provide usable wind speed measurements ...
The Nature of the Stochastic Wind Forcing of ENSO
Publisher: American Meteorological Society
Abstract: AbstractEl Niño?Southern Oscillation (ENSO) is commonly viewed as a low-frequency tropical mode of coupled atmosphere?ocean variability energized by stochastic wind forcing. Despite many studies, however, the nature of ...
Latitudinal Variations of the Convective Source and Propagation Condition of Inertio-Gravity Waves in the Tropics
Publisher: American Meteorological Society
Abstract: Latitudinal variations of the convective source and vertical propagation condition of inertio-gravity waves (IGWs) in the tropical region (30°S?30°N) are examined using high-resolution Global Cloud Imagery (GCI) and 6-hourly ...
A Characterization of Tropical Transient Activity in the CAM3 Atmospheric Hydrologic Cycle
Publisher: American Meteorological Society
Abstract: The Community Atmosphere Model version 3 (CAM3) is the latest generation of a long lineage of general circulation models produced by a collaboration between the National Center for Atmospheric Research (NCAR) and the ...
Uncertainties in Ocean Latent Heat Flux Variations over Recent Decades in Satellite-Based Estimates and Reduced Observation Reanalyses
Publisher: American Meteorological Society
Abstract: Four state-of-the-art satellite-based estimates of ocean surface latent heat fluxes (LHFs) extending over three decades are analyzed, focusing on the interannual variability and trends of near-global averages and regional ...
