Investigation of polarimetric measurements of rainfall at close and distant ranges.
(2007)
As part of continuous modernization of operational weather radar systems, several government agencies have explored adding polarimetric capability to existing networks. Polarimetric measurements of rain have been previously ...
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 ...
MOISTURE SURGES OVER THE GULF OF CALIFORNIA AND RELATIONSHIPS WITH CONVECTIVE ACTIVITY
(2008)
The North American Monsoon (NAM) is characterized by widespread convective activity and rainfall that is tied to key synoptic and sub-synoptic atmospheric circulation features during summer - from mid-June to September. ...
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 ...
Assessing Dual-Doppler Vertical Velocity Retrievals from Rapid-Scan Radar Data
(2020-12)
Vertical velocity is the most difficult wind component to accurately retrieve from dual-
Doppler observations. Typical radar scans are conducted with shallow elevation angles and
therefore, the radial velocity observations ...
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 ...
A Polarimetric and Microphysical Investigation of Winter Storms
(2018-12)
The U.S. WSR-88D network has been upgraded to polarimetric capabilities, providing dual-polarization data for regions of the country never before sampled by polarimetric radar and allowing for an unprecedented view into ...
A Multiscale Investigation of the 26–27 April 2011 Tornado Outbreak
(2021-12)
One of the most prolific tornado outbreaks ever documented occurred on 26–27 April 2011 and comprised three successive episodes of tornadic convection that primarily impacted the southeastern United States, including two ...
