Rainfall Occurrence in the U.S. Warm Season: The Diurnal Cycle
Publisher: American Meteorological Society
Abstract: The diurnal occurrence of warm-season rainfall over the U.S. mainland is examined, particularly in light of forcings at multiple scales. The analysis is based on a radar dataset of 12-seasons duration covering the U.S. ...
Multiparameter Radar Measurements in Colorado Convective Storms. Part II: Hail Detection Studies
Publisher: American Meteorological Society
Abstract: In this part II paper we focus on hail detection using the NCAR CP-2 radar measurements from which ZH, ZDR, LDR, and dual-frequency ratio can be derived. A major feature of this paper relates to rigorous computations of ...
Long-Lived Mesoconvective Vortices and Their Environment. Part I: Observations from the Central United States during the 1998 Warm Season
Publisher: American Meteorological Society
Abstract: Observations from the modernized United States National Weather Service (NWS) data network are used to assess the frequency and general characteristics of midtropospheric cyclonic vortices (MCVs) generated by mesoscale ...
Initiation of Precipitation Episodes Relative to Elevated Terrain
Publisher: American Meteorological Society
Abstract: The western and central United States experience a pronounced diurnal cycle in rainfall during the warm season. Over the higher terrain west of 105°W, most precipitation occurs in the afternoon, whereas the central United ...
Trade Wind Rainfall near the Windward Coast of Hawaii
Publisher: American Meteorological Society
Abstract: A dynamically based mesoscale climatology of rainfall and other data are examined for typical trade wind conditions near Hawaii. Relative distributions of rainfall are deduced from radar reflectivity data for a 4000 km2 ...
Tropical Island Convection in the Absence of Significant Topography. Part II: Nowcasting Storm Evolution
Publisher: American Meteorological Society
Abstract: This paper examines influences on the short-range prediction of organized convection under conditions of strong diurnal forcing. The analyses are based on data provided by the Maritime Continent Thunderstorm Experiment, ...
Initiation of Deep Convection along Boundary Layer Convergence Lines in a Semitropical Environment
Publisher: American Meteorological Society
Abstract: The initiation of deep convection through forcing along boundary layer convergence lines is examined using observations from the Convection and Precipitation/Electrification Experiment conducted in east-central Florida ...
A Study of Thunderstorm Microphysics with Multiparameter Radar and Aircraft Observations
Publisher: American Meteorological Society
Abstract: Excellent agreement was found between multiparameter radar signatures of hail, raindrops, and mixed-phase precipitation and in situ precipitation particle measurements made by aircraft in a northeastern Colorado hail-storm. ...
Inferences of Predictability Associated with Warm Season Precipitation Episodes
Publisher: American Meteorological Society
Abstract: Herein preliminary findings are reported from a radar-based climatology of warm season precipitation ?episodes.? Episodes are defined as time?space clusters of heavy precipitation that often result from sequences of organized ...
