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 ...
Effects of nesting frequency and lateral boundary perturbations on the dispersion of limited-area ensemble forecasts.
(2003)
To help restore error variance and LAM ensemble dispersion, a new method is developed to apply statistically consistent LBC perturbations that remain spatially and temporally coherent while passing through the boundaries. ...
The effects of wind shear on convective boundary layer entrainment.
(2004)
24 large eddy simulations (LES) were conducted for CBLs growing under varying conditions of surface buoyancy flux, free atmospheric stratification, and wind shear. With the intent of elucidating the effects of surface layer ...
Alterations in land surface-atmosphere processes resulting from the 1988 Greater Yellowstone Area fires.
(2004)
Meteorological observations for the 10-year period 1984 to 1993 have been collected from 178 stations within the GYA, quality assured, and spatially and temporally interpolated to produce gridded data suitable for model ...
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 ...
