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 ...
Relationships between thunderstorm mesoscale circulation and tornadogenesis.
(1983)
The data show that vertical vorticity production in tornadic storms begins at the very roots of the updraft as horizontal vorticity associated with low level environmental air is tilted toward the vertical. The vertical ...
The value of point-scale measurements of soil moisture in planetary boundary layer simulations.
(2001)
This study also investigates the sensitivity of ground heat flux estimates at NORM to naturally occurring variability in soil-water content from field samples as well as instrumentation biases associated with the in situ ...
A study of hail production in a supercell storm using a Doppler derived wind field and a numerical hail growth model.
(1980)
An investigation is made into the hail production characteristics of a supercell-type storm that occurred in Central Oklahoma on 29 May 1976. The main research tool employed is a three dimensional numerical hail growth ...
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 ...
