Air-sea heat exchange along the northern sea surface temperature front in the eastern tropical Pacific

Thum, Nicolai (2001-02-22)

The atmospheric response to the oceanic forcing in the eastern Pacific along the northern equatorial sea surface temperature (SST) front is investigated in terms of sensible and latent heat flux during the 6-month peri ...
An examination of structure and parameterization of turbulence in the stably-stratified atmospheric boundary layer

Ruscher, Paul Harold (1987-10-02)

The very stable boundary layer is a region of the atmosphere typified by large vertical gradients of temperature and momentum. Analysis of very stable atmospheric flows is complicated by the presence of nonlinear inter ...
Flow over surface discontinuities in a marine environment

Moore, Erin M. (2002-07-25)

This study concentrates on analysis of LongEZ aircraft data taken offshore of the Atlantic Coast of the United States. Due to the land structure of the region, it was possible to isolate the effect of narrow land on ai ...
INDOEX aerosol optical depths and radiative forcing derived from AVHRR

Tahnk, William Richard (2001-02-02)

The Indian Ocean Experiment (INDOEX) had as a primary objective determining the radiative forcing due to anthropogenic aerosols over climatologically significant space and time scales: the Indian Ocean during the wint ...
The influence of small scale variability on scaling relationships describing atmospheric turbulence

Howell, James Frederick (1993-05-19)

The statistics describing variations of turbulent motions within the so called inertial range of length scales depend on the scale over which the motions are varying and the "average" rate at which the turbulent kineti ...
Local and area-averaged momentum fluxes

Nakamura, Reina (1999-10-21)
A modeling study of katabatic flows

Smith, Craig M. (2003-09-04)

A modeling study is undertaken to better understand the physics of katabatic flows. This study is divided into three topics; a comparison between a large eddy simulation (LES) and a mesoscale model of katabatic flows, ...
Modelling and analysis of geophysical turbulence : use of optimal transforms and basis sets

Gamage, Nimal K. K. (1990-08-06)

The use of efficient basis functions to model and represent flows with internal sharp velocity gradients, such as shocks or eddy microfronts, are investigated. This is achieved by analysing artificial data, observed at ...
A nonlocal mixing formulation for the atmospheric boundary layer

Frech, Michael C. (1993-12-17)

A two-scale approach for the turbulent mixing of momentum in an unstable stratified boundary layer is proposed in an attempt to eliminate existing inconsistencies between parameterized mixing of heat and momentum. The ...
Observational studies of stable nocturnal boundary layers: intermittent turbulence, sensible heat budgets and observational errors

Nakamura, Reina (2005-02-04)

Atmospheric boundary layers become stably stratified at night over land when the surface becomes colder than the air layer above. In stable nocturnal boundary layers (SNBL), turbulence becomes weak and intermittent, terr ...
The relationship of precipitation in the western United States to variations in the outgoing long-wave radiation field over the tropical Pacific : the role of the mid-latitude circulation

Twining, David S. (1995-02-24)

The relationship between the outgoing long-wave radiation (OLR) field over the tropical Pacific and wintertime monthly precipitation for the western U. S. is investigated, using the mid-latitude upper-air circulation ...
Stability analysis of homogeneous shear flow : the linear and nonlinear theories and a Hamiltonian formulation

Hagelberg, Carl R. (1989-10-17)

The stability of steady-state solutions of the equations governing two-dimensional, homogeneous, incompressible fluid flow are analyzed in the context of shear-flow in a channel. Both the linear and nonlinear theories ...
Structure of turbulence in stratified flow : aircraft data from SESAME and ALPEX

Gamage, Nimal K. K. (1986-03-07)

Several horizontal flight segments from SESAME and ALPEX are studied using structure functions and specral analysis methods. Theoretical analysis of the relative errors in structure function and correlation function i ...
A study of positive cloud-to-ground lightning flashes in mesoscale convective systems

Lu, Chungu (1988-08-05)

This study is mainly concentrated on examining the positive cloud-to-ground lightning activity associated with Mesoscale Convective Systems. Six MCS events which occurred during the O.K. PRE-STORM program in 1985 are s ...
Sudden changes in local mean values demarcate geophysical regimes

Howell, James F., 1965- (1995-12-08)

Sudden changes occur where the mean values associated with two adjacent non-overlapping windows of data are anomalously different, and the transition between the window means occurs over a scale that is small relative ...
Turbulent and gravity wave transport in the free atmosphere

Kim, Jinwon (1990-11-29)
Turbulent structure in the bora and stable boundary layer

Frank, Helmut P. (1986-04-03)

An eigenvector analysis of the velocity-temperature correlation matrix is applied to clear-air turbulence measured by aircraft in the Bora. The eigenvectors are identified with the main eddies of the turbulence. This ...
