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...

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,...

Creator:: Seaman, Nelson L., Gaudet, Brian J., Stauffer, David R., Mahrt, Larry, Richardson, Scott J., Zielonka, Jeffrey R., and Wyngaard, John C.
Abstract:: Numerical weather prediction models often perform poorly for weakly forced, highly variable winds in nocturnal stable boundary layers (SBLs). When used as input to air-quality and dispersion models, these wind errors can lead to large errors in subsequent plume forecasts. Finer grid resolution and improved model numerics and physics can...

Creator:: Sun, Jielun, Mahrt, Larry, Banta, Robert M., and Pichugina, Yelena L.
Abstract:: An investigation of nocturnal intermittent turbulence during the Cooperative Atmosphere Surface Exchange Study in 1999 (CASES-99) revealed three turbulence regimes at each observation height: 1) regime 1, a weak turbulence regime when the wind speed is less than a threshold value; 2) regime 2, a strong turbulence regime when the...

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:: Sun, Jielun, Mahrt, Larry, Nappo, Carmen, and Lenschow, Donald H.
Abstract:: The authors investigate atmospheric internal gravity waves (IGWs): their generation and induction of global intermittent turbulence in the nocturnal stable atmospheric boundary layer based on the new concept of turbulence generation discussed in a prior paper by Sun et al. The IGWs are generated by air lifted by convergence forced...

Abstract:: The flux-gradient relationship of water vapor Fq was obtained from the Cooperative Atmosphere-Surface Exchange Study-1999 (CASES-99) field experiment, which was conducted on a flat and grassy field in the southeastern part of Kansas, USA, during October 1999. The CASES-99 data include turbulence measurements of wind, temperature, and vapor density along...

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...

Abstract:: Relationships among the horizontal pressure gradient, the Coriolis force, and the vertical momentum transport by turbulent fluxes are investigated using data collected from the 1999 Cooperative Atmosphere-Surface Exchange Study (CASES-99). Wind toward higher pressure (WTHP) adjacent to the ground occurred about 50% of the time. For wind speed at 5...
