A satellite-derived Climatology of Global Ocean Winds (COGOW) on a 0.5° latitude by 0.5° latitude grid is presented based on 5-years (August 1999 July 2004) of measurements from the SeaWinds scatterometer that was launched on 19 June 1999 onboard the QuikSCAT satellite. SeaWinds is an active microwave radar that estimates...
In a recent paper, Sandwell and Agreen [1984; hereafter SA]
presented figures of global seasonal wind speed and sea state
as measured by the GEOS 3 satellite altimeter. Since that
time, Chelton and McCabe [1985; hereafter CM] have found
that problems exist in the algorithms used to retrieve wind
speed...
The wind speed and significant wave height (H1/3) dependencies of the sea state is in altimeter estimates of sea level, expressed in the form ∆hSSB=bH1/3, are examined from least squares analysis of 21 cycles of collinear TOPEX data. The bias coefficient b is found to increase in magnitude with increasing...
The impact of SST specification on low-level winds in the operational ECMWF numerical weather prediction model is investigated in the eastern tropical Pacific from comparisons of ECMWF wind stress fields with QuikSCAT satellite scatterometer observations of wind stress during the August–December cold seasons of 2000 and 2001. These two time...
Surface drifters were depldyed and tracked over the continental shelf and upper continental slope off central California between Point Conception and Point Sur. The drifters were deployed and tracked from aircraft by Aero-Marine Surveys, Inc. under subcontract to Raytheon Service Company as part of the Central California Coastal Circulation Study...
Seasonal variability of alongshore geostrophic velocity relative to 500 dbar is examined from 23 years
of hydrographic data along two sections off central California (one off Point Sur and the other off Point
Conception). The seasonal cycles are determined by least square fits of the gappy data records to
harmonics...
The importance of wind-driven latent heat fluxes for supporting tropical intraseasonal precipitation variability is analyzed. Tropical
intraseasonal variability in the west pacific and Indian ocean is analyzed for northern and southern hemisphere summer during 1999-2005 using
satellite and buoy observations. A composite analysis of QuikSCAT ocean vector winds and TRMM...
In this thesis, data collected during the Dynamics of the Madden Julian Oscillation (DYNAMO) field campaign, conducted in the Indian Ocean in Fall of 2011, is used to compute heat fluxes at the air-sea interface by evaluating eddy covariances and bulk aerodynamic formulae. Errors in daily average gridded fluxes computed...
Carbon dioxide (CO₂) fluxes between the ocean and atmosphere on continental margins are difficult to diagnose because these regions experience large variability over spatial and temporal scales spanning meters to basins and hours to years, respectively. In a global sense, continental margins could represent a significant atmospheric CO₂ sink, equivalent...
