RISThe Nonlinear Evolution of Idealized, Unforced, Conditional Symmetric Instability: A Numerical Study
Publisher: American Meteorological Society
Abstract: A two-dimensional version of the Penn State?NCAR mesoscale model (MM4) has been used to simulate the life cycle of conditional symmetric instability (CSI) under conditions of no deformational or planetary boundary layer ...
The Mesoscale and Microscale Structure and organization of Clouds and precipitation in Midlatitude Cyclones. Part V: The Substructure of Narrow Cold-Frontal Rainbands
Publisher: American Meteorological Society
Abstract: The organization and structure of a narrow cold-frontal rainband (NCFR) on the small mesoscale and the microscale have been investigated through quantitative radar reflectivity, Doppler radar observations, airborne ...
Nonlinear Hydrostatic Conditional Symmetric Instability: Implications for Numerical Weather Prediction
Publisher: American Meteorological Society
Abstract: A simplified two-dimensional version of the Pennsylvania State University-NCAR Mm scale Model (MM4) was used to investigate the nonlinear evolution of unforced conditional symmetric instability (CSI). Sensitivity tests ...
Model Generation of Spurious Gravity Waves due to Inconsistency of the Vertical and Horizontal Resolution
Publisher: American Meteorological Society
Abstract: The importance of the consistency between the vertical and horizontal resolution of numerical models has been suggested in recent studies. In this context, consistency means that the vertical scales that are physically ...
A Bulk Turbulent Air–Sea Flux Algorithm for High-Wind, Spray Conditions
Publisher: American Meteorological Society
Abstract: Sensible and latent heat can cross the air?sea interface by two routes: as interfacial fluxes controlled by molecular processes right at the interface, and as spray fluxes from the surface of sea spray droplets. Once the ...
The Summertime Arctic Atmosphere: Meteorological Measurements during the Arctic Ocean Experiment 2001
Publisher: American Meteorological Society
Abstract: An atmospheric boundary layer experiment into the high Arctic was carried out on the Swedish ice-breaker Oden during the summer of 2001, with the primary boundary layer observations obtained while the icebreaker drifted ...

Coastal Orographic Rainfall Processes Observed by Radar during the California Land-Falling Jets Experiment
Publisher: American Meteorological Society
Abstract: Radar and rain gauge observations collected in coastal mountains during the California Land-Falling Jets Experiment (CALJET) are used to diagnose the bulk physical properties of rainfall during a wet winter season ...
Application of TRMM PR and TMI Measurements to Assess Cloud Microphysical Schemes in the MM5 for a Winter Storm
Publisher: American Meteorological Society
Abstract: This paper uses observations from Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) and microwave imager (TMI) to evaluate the cloud microphysical schemes in the fifth-generation Pennsylvania State ...
Variations Associated with Cores and Gaps of a Pacific Narrow Cold Frontal Rainband
Publisher: American Meteorological Society
Abstract: A NOAA P-3 instrumented aircraft observed an intense, fast-moving narrow cold frontal rainband (NCFR) as it approached the California coast on 19 February 2001 during the Pacific Coastal Jets Experiment. Airborne Doppler ...
