On the Coupling of Wind Stress and Sea Surface Temperature

Creator:: Samelson, R. M., Skyllingstad, E. D., Chelton, D. B., Esbensen, S. K., O'Neill, L. W., and Thum, N.
Abstract:: A simple quasi-equilibrium analytical model is used to explore hypotheses related to observed spatial correlations between sea surface temperatures and wind stress on horizontal scales of 50–500 km. It is argued that a plausible contributor to the observed correlations is the approximate linear relationship between the surface wind stress and...

Subgrid Surface Fluxes in Fair Weather Conditions during TOGA COARE: Observational Estimates and Parameterization

Creator:: Vickers, Dean and Esbensen, Steven K.
Abstract:: Bulk aerodynamic formulas are applied to meteorological data from low-altitude aircraft flights to observational estimates of the subgrid enhancement of momentum, sensible heat, and latent heat the atmospheric–oceanic boundary in light wind, fair weather conditions during TOGA COARE Global Atmosphere Coupled Ocean–Atmosphere Response Experiment). Here, subgrid enhancement the contributions of...

Estimation of Surface Heat Flux

Creator:: Sun, Jielun, Esbensen, Steven K., and Mahrt, L.
Abstract:: The authors reconsider the problem of estimating the sensible heat transfer at the earth's surface from direct measurements of turbulent fluxes in the atmospheric boundary layer. For simplicity, only horizontally homogeneous conditions are considered for a thin atmospheric layer containing no liquid water, adjacent to the earth's ground surface. Applying...

The Amplification of East Pacific Madden–Julian Oscillation Convection and Wind Anomalies during June–November

Creator:: Maloney, Eric D. and Esbensen, Steven K.
Abstract:: Madden–Julian oscillation (MJO) wind and convection anomalies are locally amplified over the northeast Pacific warm pool during June–November. Composite analysis using NCEP reanalysis data indicates that perturbation available potential energy (PAPE) production through the positive correlation of intraseasonal temperature and convective diabatic heating anomalies supports the local intensification of MJO-related...

A Modeling Study of Summertime East Pacific Wind-Induced Ocean–Atmosphere Exchange in the Intraseasonal Oscillation

Creator:: Maloney, Eric D. and Esbensen, Steven K.
Abstract:: Intraseasonal precipitation variability over the northeast Pacific warm pool during June–October in the National Center for Atmospheric Research Community Atmosphere Model 2.0.1 with a relaxed Arakawa–Schubert convection parameterization is found to be strongly sensitive to wind-induced variations in surface latent heat flux. A control simulation with interactive surface fluxes produces...

Enhancement of Tropical Ocean Evaporation and Sensible Heat Flux by Atmospheric Mesoscale Systems

Creator:: Esbensen, Steven K. and McPhaden, Michael J.
Abstract:: The enhancement of monthly averaged evaporation by atmospheric mesoscale systems is estimated from long-term hourly observations of surface meteorological data from the Tropical Ocean Global Atmosphere (TOGA) Tropical Atmosphere Ocean (TAO) buoy moorings over the equatorial Pacific Ocean and a bulk aerodynamic flux algorithm developed as a result of the...

Satellite and Buoy Observations of Boreal Summer Intraseasonal Variability in the Tropical Northeast Pacific

Creator:: Maloney, Eric D. and Esbensen, Steven K.
Abstract:: Tropical intraseasonal variability in the eastern North Pacific during June–September of 2000–03 is analyzed using satellite and buoy observations. Quick Scatterometer ocean vector winds and the Tropical Rainfall Measuring Mission (TRMM) precipitation indicate that periods of anomalous surface westerly flow over the east Pacific warm pool during a summertime intraseasonal...

Observations of Coupling between Surface Wind Stress and Sea Surface Temperature in the Eastern Tropical Pacific

Creator:: Chelton, Dudley B., Esbensen, Steven K., Schlax, Michael G., Thum, Nicolai, Freilich, Michael H., Wentz, Frank J., Gentemann, Chelle L., McPhaden, Michael J., and Schopf, Paul S.
Abstract:: Satellite measurements of surface wind stress from the QuikSCAT scatterometer and sea surface temperature (SST) from the Tropical Rainfall Measuring Mission Microwave Imager are analyzed for the three-month period 21 July–20 October 1999 to investigate ocean–atmosphere coupling in the eastern tropical Pacific. Oceanic tropical instability waves (TIWs) with periods of...

Covariability of Surface Wind and Stress Responses to Sea Surface Temperature Fronts

Creator:: O'Neill, Larry W., Chelton, Dudley B., and Esbensen, Steven K.
Abstract:: The responses of surface wind and wind stress to spatial variations of sea surface temperature (SST) are investigated using satellite observations of the surface wind from the Quick Scatterometer (QuikSCAT) and SST from the Advanced Microwave Scanning Radiometer on the Advanced Microwave Scanning Radiometer for Earth Observing System (EOS) (AMSR-E)...

The Dynamics of the ENSO–Atlantic Hurricane Teleconnection: ENSO-Related Changes to the North African–Asian Jet Affect Atlantic Basin Tropical Cyclogenesis

Creator:: Shaman, Jeffrey, Esbensen, Steven K., and Maloney, Eric D.
Abstract:: The nature of the teleconnection linking ENSO variability with Atlantic basin tropical storm formation is investigated. Solutions of the linearized barotropic vorticity equation forced with August–October El Niño event divergence produce upper-tropospheric vorticity anomalies over the Sahel and at the mouth of the North African–Asian (NAA) jet over the tropical...
