RISConvection Initiation Associated with a Sea-Breeze Front, a Gust Front, and Their Collision
Publisher: American Meteorological Society
Abstract: The initiation of convection associated with a sea-breeze front, a gust front, and their collision is analyzed using data collected in east-central Florida during the Convection and Precipitation/Electrification project. ...
Mesoscale Variations of the Atmospheric Snow Line over the Northern Sierra Nevada: Multiyear Statistics, Case Study, and Mechanisms
Publisher: American Meteorological Society
Abstract: bservations from several mountain ranges reveal that the height of the transition from snowfall to rainfall, the snow line, can intersect the terrain at an elevation hundreds of meters below its elevation in the free air ...
Terrain-Trapped Airflows and Orographic Rainfall along the Coast of Northern California. Part I: Kinematic Characterization Using a Wind Profiling Radar
Publisher: American Meteorological Society
Abstract: AbstractThis study develops an objective method of identifying terrain-trapped airflows (TTAs) along the coast of Northern California and documenting their impact on orographic rainfall. TTAs are defined as relatively ...
Orographic Precipitation Forcing along the Coast of Northern California during a Landfalling Winter Storm
Publisher: American Meteorological Society
Abstract: his study documents orographic precipitation forcing along the coastal mountains of Northern California during the landfall of a significant winter storm over the period 16?18 February 2004. The primary observing asset is ...
Kinematic, Dynamic, and Thermodynamic Analysis of a Weakly Sheared Severe Thunderstorm over Northern Alabama
Publisher: American Meteorological Society
Abstract: A kinematic, dynamic, and thermodynamic analysis of a weakly sheared, airmass thunderstorm observed over northern Alabama is presented. Most notable is the fact that the dominant cell in this storm closely resembles the ...
An Observational Study of Atmospheric Bore Formation from Colliding Density Currents
Publisher: American Meteorological Society
Abstract: Observations from east-central Florida during the Convection and Precipitation/Electrification (CaPE) experiment are used to investigate the factors that influence atmospheric bore formation from colliding density currents. ...
Terrain-Trapped Airflows and Orographic Rainfall along the Coast of Northern California. Part II: Horizontal and Vertical Structures Observed by a Scanning Doppler Radar
Publisher: American Meteorological Society
Abstract: AbstractThis study documents the mean properties and variability of kinematic and precipitation structures associated with orographic precipitation along the coast of Northern California in the context of terrain-trapped ...
Variability of Graupel and Snow Observed in Tropical Oceanic Convection by Aircraft during TRMM KWAJEX
Publisher: American Meteorological Society
Abstract: Empirical characterization of graupel and snow in precipitating tropical convective clouds is important for refining satellite precipitation retrieval algorithms and cloud-resolving and radiative transfer models. Microphysics ...
A Polarimetric Radar Approach to Identify Rain, Melting-Layer, and Snow Regions for Applying Corrections to Vertical Profiles of Reflectivity
Publisher: American Meteorological Society
Abstract: This article describes polarimetric X-band radar-based quantitative precipitation estimations (QPE) under conditions of low freezing levels when, even at the lowest possible elevation angles, radar resolution volumes at ...
Kinematic, Thermodynamic, and Visual Structure of Low-Reflectivity Microbursts
Publisher: American Meteorological Society
Abstract: On 9 July 1987, a series of low-reflectivity microbursts were studied over Colorado using dual-Doppler analyses, cloud photogrammetry, and in situ measurements collected by aircraft. These types of wind-shear events are ...
