RISThe New York Bight Jet: Climatology and Dynamical Evolution
Publisher: American Meteorological Society
Abstract: This paper describes the southerly New York Bight (NYB) jet (11?17 m s?1) that develops primarily during the warm season just above the surface offshore (east) of the northern New Jersey coast and south of Long Island (the ...
Diagnosing Snowband Predictability Using a Multimodel Ensemble System
Publisher: American Meteorological Society
Abstract: he forecast uncertainty of mesoscale snowband formation and evolution is compared using predictions from a 16-member multimodel ensemble at 12-km grid spacing for the 25 December 2002, 12 February 2006, and 14 February ...
Evolution of Mesoscale Precipitation Band Environments within the Comma Head of Northeast U.S. Cyclones
Publisher: American Meteorological Society
Abstract: This paper explores the mesoscale forcing and stability evolution of intense precipitation bands in the comma head sector of extratropical cyclones using the 32-km North American Regional Reanalysis, hourly 20-km Rapid ...
High-Resolution Observations and Model Simulations of the Life Cycle of an Intense Mesoscale Snowband over the Northeastern United States
Publisher: American Meteorological Society
Abstract: This paper investigates the structural and dynamical evolution of an intense mesoscale snowband occurring 25?26 December 2002 over the northeastern United States. Dual-Doppler, wind profiler, aircraft, and water vapor ...
The Role of Moist Processes in the Formation and Evolution of Mesoscale Snowbands within the Comma Head of Northeast U.S. Cyclones
Publisher: American Meteorological Society
Abstract: The role of moist processes in regulating mesoscale snowband life cycle within the comma head portion of three northeast U.S. cyclones is investigated using piecewise potential vorticity (PV) inversion, modeling experiments, ...
Operational Forecaster Uncertainty Needs and Future Roles
Publisher: American Meteorological Society
Abstract: Key results of a comprehensive survey of U.S. National Weather Service operational forecast managers concerning the assessment and communication of forecast uncertainty are presented and discussed. The survey results ...
Using Percentiles to Communicate Snowfall Uncertainty
Publisher: American Meteorological Society
Abstract: n objective technique to determine forecast snowfall ranges consistent with the risk tolerance of users is demonstrated. The forecast snowfall ranges are based on percentiles from probability distribution functions that ...
A Forecast Strategy for Anticipating Cold Season Mesoscale Band Formation within Eastern U.S. Cyclones
Publisher: American Meteorological Society
Abstract: An ingredients-based, time- and scale-dependent forecast strategy for anticipating cold season mesoscale band formation within eastern U.S. cyclones is presented. This strategy draws on emerging conceptual models of mesoscale ...
An Observational Study of Cold Season–Banded Precipitation in Northeast U.S. Cyclones
Publisher: American Meteorological Society
Abstract: A climatological and composite study of banded precipitation in the northeast United States during the cold season (October?April) is presented. Precipitation systems in the northeast United States in April 1995 and from ...
