Barotropic Rossby Wave Dynamics of Zonally Varying Upper-Level Flows during Northern Winter
Publisher: American Meteorological Society
Abstract: The evolution of linear Rossby waves on representative zonally varying upper-tropospheric flows is examined. Structures associated with maximum perturbation energy growth over both short and long time intervals are obtained. ...
Barotropic Instability and Optimal Perturbations of Observed Nonzonal Flows
Publisher: American Meteorological Society
Abstract: An eigenvalue analysis of a divergent barotropic model on a sphere is extended to the formulation of a global optimization problem, whose solution selects an initial perturbation that evolves into the most energetic structure ...
Observations of Horizontal Velocities and Vertical Displacements in the Equatorial Pacific Ocean Associated with the Early Stages of the 1982/83 El Niño
Publisher: American Meteorological Society
Abstract: Pacific near-equatorial absolute-velocity data and CTD?O2 observations collected from the R.V. Conrad in the northern fall of 1982 are presented. Quite by chance, the cruise took place during the early stages of the 1982/83 ...
Free Barotropic Rossby Wave Dynamics of the Wintertime Low-Frequency Flow
Publisher: American Meteorological Society
Abstract: In recent years much attention has been given to Rossby wave propagation and dispersion on representative zonally and meridionally varying background flows in the atmosphere. Particular emphasis has been placed on the ...
