Wind Speed and Stability Effects on Coupling between Surface Wind Stress and SST Observed from Buoys and Satellite

Creator:: O'Neill, Larry W.
Abstract:: The surface wind and stress responses to sea surface temperature (SST) are examined using collocated moored buoy and satellite observations in the Gulf Stream and the eastern equatorial Pacific. Using 17 buoy pairs, differences in the wind speed, 10-m equivalent neutral wind speed (ENW), and surface wind stress magnitude between...

Processes Contributing to Bering Sea Temperature Variability in the Late 20th and Early 21st Century

Creator:: Hayden, Emily E. and O'Neal, Larry W.
Abstract:: Over recent decades, the Bering Sea has experienced oceanic and atmospheric climate extremes, including record warm ocean temperature anomalies and marine heatwaves (MHWs), and increasingly variable air-sea heat fluxes. In this work, we assess the relative roles of surface forcing and ocean dynamical processes on mixed layer temperature (MLT) tendency...

Estimation of Time-Averaged Surface Divergence and Vorticity from Satellite Ocean Vector Winds

Creator:: O'Neill, Larry W., Haack, Tracy, and Durland, Theodore
Abstract:: Two methods of computing the time-mean divergence and vorticity from satellite vector winds in rain-free (RF) and all-weather (AW) conditions are investigated. Consequences of removing rain-contaminated winds on the mean divergence and vorticity depend strongly on the order in which the time-average and spatial derivative operations are applied. Taking derivatives...

Impact of soil water property parameterization on atmospheric boundary layer simulation

Creator:: Cuenca, Richard H., Ek, Michael, and Mahrt, Larry
Abstract:: Both the form of functional relationships applied for soil water properties and the natural field-scale variability of such properties can significantly impact simulation of the soil-plant-atmosphere system on a diurnal timescale. Various input parameters for soil water properties including effective saturation, residual water content, anerobiosis point, field capacity, and permanent...

Fine-scale variability at 140°W in the Equatorial Pacific

Creator:: Chereskin, T. K., Moum, James N., Stabeno, P. J., Caldwell, Douglas R., Paulson, C. A., Regier, L. A., and Halpern, D.
Abstract:: In November-December 1984 we carried out an intensive 12-day upper ocean sampling program on the equator at 140°W as part of the Tropic Heat Experiment. From our observations we constructed hourly averaged profiles of temperature, salinity, σ₁, turbulent kinetic energy dissipation rate, and horizontal velocity. These data were used to...

High electron mobility W-doped In₂O₃ thin films by pulsed laser deposition

Creator:: Newhouse, Paul F., Park, C.-H., Keszler, Douglas A., Tate, J., Nyholm, P. S., and Tate, Janet
Abstract:: High electron mobility thin films of In₂₋ₓWₓO₃₊y(0≤x≤0.075) were prepared on amorphous SiO₂ and single-crystal yttria-stablized zirconia (001) substrates by pulsed laser deposition. Mobilities ranged between 66 and 112 cm² /Vs depending on the substrate type and deposition conditions, and the highest mobility was observed at a W-dopant concentration of x~0.03....

Vertically integrated sensible-heat budgets for stable nocturnal boundary layers

Creator:: Nakamura, Reina and Mahrt, Larry
Abstract:: The stable nocturnal boundary layer is commonly viewed or modelled as a balance between the temperature tendency (cooling) and vertical heat-flux divergence. Sometimes the radiative-flux divergence is also included. This perspective has dictated the design of field experiments for investigating stable nocturnal boundary layers. Tower-based micrometeorological data from three field...

Comparison of heat and moisture fluxes from a modified soil-plant-atmosphere model with observations from BOREAS

Creator:: Lee, Young-Hee and Mahrt, Larry
Abstract:: This study evaluates the prediction of heat and moisture fluxes from a new land surface scheme with eddy correlation data collected at the old aspen site during the Boreal Ecosystem-Atmosphere Study (BOREAS) in 1994. The model used in this study couples a multilayer vegetation model with a soil model. Inclusion...

Evaluation of the air-sea bulk formula and sea-surface temperature variability from observations

Creator:: Vickers, Dean and Mahrt, Larry
Abstract:: Eddy‐correlation fluxes are compared to air‐sea fluxes predicted by a widely used bulk flux formulation without wave‐state effects. Systematic discrepancies are found. For example, the model approximately equates the roughness lengths for heat and moisture; however, the observed roughness length for heat (zoh) exceeds that for moisture (zoq) by an...

Flux-gradient relationship, self-correlation and intermittency in the stable boundary layer

Creator:: Klipp, Cheryl L. and Mahrt, Larry
Abstract:: The correlation between dimensionless shear ϕₘ and dimensionless height z/L, where L is the Obukhov length, for stable conditions is strongly influenced by self‐correlation for the present datasets. This effect is quite large for stronger stability but still significant for near‐neutral conditions. A conditional analysis of nocturnal stable boundary‐layer data,...
