Recent interdecadal variations in the tropical atmosphere: Evidence and idealized GCM simulations.
(1998)
A series of model integrations, forced with different SST perturbations over the tropical central and eastern Pacific, has been performed using the ECHAM4 GCM in an attempt to simulate the spatial patterns in tropical ...
Ultragiant aerosol growth by collection within a warm continental cumulus congestus.
(1998)
Results suggest that UGA are only marginally important for warm rain formation in a short-lived cloud such as that studied here. Although the cloud has a very high liquid water content $\rm ({>} 5\ g\ m\sp{-3})$ and the ...
The retrieval of initial forecast fields from single Doppler observations of a supercell thunderstorm.
(1998)
Following the velocity blending and adjustment steps, the thermodynamic retrieval is applied to both the single- and dual-Doppler derived wind fields, yielding realistic looking and qualitatively similar perturbation ...
The influence of horizontal variations in vertical shear and low-level moisture on numerically simulated convective storms.
(1999)
Severe storms are typically simulated assuming either an idealized, horizontally homogeneous environment or an observed inhomogeneous environment. These represent opposite ends of the spectrum, and both have limitations ...
An investigation of the diurnal variability of the Central Colorado downslope windstorm.
(1997)
An interesting observation is made regarding the strongly heated experiments. The high drag state associated with the strong mountain wave and downslope windstorm control runs prevail but at a reduced level. The numerical ...
Numerical simulation of nonlinear buoyancy waves in the lower atmosphere.
(1997)
A 2D dry incompressible vorticity-stream function model is developed and used to investigate nonlinear buoyancy waves, especially internal solitary waves and related phenomena in the lower atmosphere. Using this model some ...
On the formation of vertical vortices in the atmosphere.
(1999)
This dissertation reports on two semi-independent studies of rotating atmospheric convection. The first is an analytical investigation of the linear stability and structure of convection in a mean circular shear. The study ...
Modeling of the aerosol-cloud interactions in marine stratocumulus.
(1997)
In order to study the cloud processing of aerosols, a two-parameter drop spectrum that depends on both the drop mass and the solute mass has been introduced into the CIMMS LES model. The aerosol processing due to condensation, ...
Development of a diagnostic surface energy budget model using Oklahoma Mesonet and ARM data.
(1998)
The model was then used to calculate H at 44 sites in Oklahoma during the daytime hours of July 1997. In general, H was much larger across western Oklahoma throughout the month. On 12 July, a strong meridional gradient in ...
Large-eddy simulation of stratocumulus-topped boundary layer with an explicit and a new bulk microphysics scheme.
(1997)
The realism of the model is evaluated by a direct comparison of the model predictions with the aircraft observations of the STBL. The first case study is based on the UKMRF flight 526 measurements collected over the North ...
