Creator:: Sun, Jielun, Vandemark, Douglas, Mahrt, Larry, Vickers, Dean, Crawford, Timothy, and Vogel, Christoph
Abstract:: Spatial variations of surface stress over the coastal shoaling zone are studied offshore of Duck, North Carolina, by the LongEZ research aircraft, equipped to measure both atmospheric turbulence and oceanic waves. We find that the spatial variation of the friction velocity with offshore distance is much larger with offshore flow...

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...

Abstract:: Aircraft data collected at approximately 15 m above the sea surface in the coastal zone are analyzed to examine the spatial distribution of surface stress. Advection of stronger turbulence from land dominates the near-surface turbulence for the first few kilometers offshore. With offshore flow of warm air over cold water,...

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...

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,...

Abstract:: Whole ecosystem carbon dioxide (CO₂) exchange estimated with the eddy covariance (EC) technique has been central to studies on the responses of terrestrial ecosystems to disturbance and intra‐annual and interannual variations in climate, but challenges exist in understanding and reducing the uncertainty in estimates of net ecosystem exchange (NEE) of...

Creator:: Mahrt, Larry, Thomas, Christoph, and Prueger, J. H.
Abstract:: In this article, we examine the stochastic characteristics of non-turbulent motions in the stable boundary layer. The behaviour of mesoscale motions in the atmospheric stable boundary layer is poorly understood beyond case studies of unusually well-defined events or monotonic waves. Eight networks of wind observations are analysed in order to...

Creator:: Banta, Robert M., Mahrt, Larry, Vicker, Dean, Sun, Jielun, Balsley, Ben B., Pichugina, Yelena L., and Williams, Eric J.
Abstract:: The light-wind, clear-sky, very stable boundary layer (vSBL) is characterized by large values of bulk Richardson number. The light winds produce weak shear, turbulence, and mixing, and resulting strong temperature gradients near the surface. Here five nights with weak-wind, very stable boundary layers during the Cooperative Atmosphere–Surface Exchange Study (CASES-99)...

Creator:: Ha, Kyung-Ja, Shin, Sun-Hee, and Mahrt, Larry
Abstract:: This study examines the spatial variation of the wind field observed in the coastal zone of southeast Korea with its complex terrain, using measurements from a regional network 75 km across and centered about Busan. Results are compared with observations from an inland regional network centered around Daegu, Korea, with...

III, Yue, D. K. P., and Zappa, Chris
Abstract:: The Office of Naval Research's Coupled Boundary Layers and Air–Sea Transfer (CBLAST) program is being conducted to investigate the processes that couple the marine boundary layers and govern the exchange of heat, mass, and momentum across the air–sea interface. CBLAST-LOW was designed to investigate these processes at the low-wind extreme...
