Evaluating Formulations of Stable Boundary Layer Height

Creator:: Vickers, D. and Mahrt, L.
Abstract:: Stable boundary layer height h is determined from eddy correlation measurements of the vertical profiles of the buoyancy flux and turbulence energy from a tower over grassland in autumn, a tower over rangeland with variable snow cover during winter, and aircraft data in the stable marine boundary layer generated by...

A Parallel Algorithm for Variational Assimilation in Oceanography and Meteorology

Creator:: Bennett, Andrew F. and Baugh, Jerome R.
Abstract:: A parallel algorithm is described for variational assimilation of observations into oceanic and atmospheric models. The algorithm may be coded first for execution on a serial computer and then trivially modified for execution on a parallel computer such as the Intel iPSC/860. The speedup factor for parallel execution is roughly...

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...

Formulation of Turbulent Fluxes in the Stable Boundary Layer

Creator:: Mahrt, L. and Vickers, Dean
Abstract:: The mixing lengths for heat and momentum are computed from seven levels of eddy correlation data during the Cooperative Atmosphere–Surface Exchange Study-1999 (CASES-99). A number of formulations of the mixing length are evaluated, including surface layer similarity theory, several hybrid similarity theories, a formulation based on the Richardson number, and...

Convectively Driven Mixing in the Bottom Boundary Layer

Creator:: Moum, J. N., Perlin, A., Klymak, J. M., Levine, M. D., Boyd, Timothy John, 1958-2013, and Kosro, P. M.
Abstract:: Closely spaced vertical profiles through the bottom boundary layer over a sloping continental shelf during relaxation from coastal upwelling reveal structure that is consistent with convectively driven mixing. Parcels of fluid were observed adjacent to the bottom that were warm (by several millikelvin) relative to fluid immediately above. On average,...

On Symmetric Instabilities in Oceanic Bottom Boundary Layers

Creator:: Allen, J. S. and Newberger, P. A.
Abstract:: Model studies of two-dimensional, time-dependent, wind-forced, stratified downwelling circulation on the continental shelf have shown that the near-bottom offshore flow can develop time- and space-dependent fluctuations involving spatially periodic separation and reattachment of the bottom boundary layer and accompanying recirculation cells. Based primarily on the observation that the potential vorticity...

General circulation model simulations of the Mars Pathfinder atmospheric structure investigation/meteorology data

Creator:: Haberle, Robert M., Joshi, Manoj M., Murphy, James R., Barnes, Jeffrey R., Schofield, John T., Wilson, Greg, Lopez-Valverde, Miguel, Hollingsworth, Jeffrey L., Bridger, Alison F. C., and Schaeffer, James
Abstract:: The NASA Ames Mars General Circulation Model is used to interpret selected results from the Mars Pathfinder atmospheric structure instrument/meteorology (ASI/MET) experiment. The present version of the model has an improved soil thermal model, a new boundary layer scheme, and a correction for non-local thermodynamic equilibrium effects at solar wavelengths....

A Raman lidar to measure water vapor in the atmospheric boundary layer

Creator:: Froidevaux, Martin, Higgins, Chad W., Simeonov, Valentin, Ristori, Pablo, Pardyjak, Eric, Serikov, Ilya, Calhoun, Ronald, van den Bergh, Hubert, and Parlange, Marc B.
Abstract:: A new multi-telescope scanning Raman lidar designed to measure the water vapor mixing ratio for a complete diurnal cycle with high raw spatial (1.25 m) and temporal (1 s) resolutions is presented. The high resolution allows detailed measurements of the lower atmosphere and offers new opportunities for boundary layer research,...

Low-Level Wind Maxima and Structure of the Stably Stratified Boundary Layer in the Coastal Zone

Creator:: Mahrt, L., Vickers, Dean, and Andreas, Edgar L.
Abstract:: A Rutan Aircraft Factory Long-EZ aircraft flew numerous low-level slant soundings on two summer days in 2001 off the northeastern coast of the United States. The soundings are analyzed here to study the nonstationary vertical structure of the wind, temperature, and turbulence. An error analysis indicates that fluxes computed from...
