RISMesoscale Rainfall Forecasts over New Zealand during SALPEX96: Characterization and Sensitivity Studies
Publisher: American Meteorological Society
Abstract: Rainfall diagnostics from 48-h, 20-km mesoscale runs of the RAMS model configured for the New Zealand region have been characterized and compared to forecasts from the U.K. Meteorological Office global model with a view ...
A Three-Dimensional Nonhydrostatic Ray-Tracing Model for Gravity Waves: Formulation and Preliminary Results for the Middle Atmosphere
Publisher: American Meteorological Society
Abstract: The WKB ray-tracing formalism is extended to accommodate internal gravity waves of all frequencies in a rotating, stratified, and compressible three-dimensional atmosphere. This includes the derivation of equations governing ...
A Critical Analysis of a Month-Long Cyclonic Anomaly in the New Zealand-Tasman Sea Region Using Isentropic Vorticity Budgets
Publisher: American Meteorological Society
Abstract: The authors investigate the processes acting during a cyclonic ?blocking? anomaly that dominated the upper troposphere in the New Zealand-Tasman Sea region during the very stormy month of August 1990. The authors use ...
Inertia–Gravity Waves Observed in the Lower Stratosphere over Macquarie Island
Publisher: American Meteorological Society
Abstract: This study examines the properties of inertia?gravity waves observed in the lower stratosphere over Macquarie Island, how these properties vary with season, and the likely source of the waves. The waves are observed in ...
