The Coupled Manifold
Publisher: American Meteorological Society
Abstract: A new method is presented to detect the portion of variability connected between two climatic fields. The method is a realization of the Procrustes problem, and it is a generalization of methods for analysis of variance ...
CORRIGENDUM

Filtering of Gravity Modes in Atmospheric Models
Publisher: American Meteorological Society
Abstract: The impact of gravity modes in atmospheric model predictions is assessed quantitatively by comparing integrations with a normal mode initialized primitive equation model and its corresponding pseudogeostrophic form to ...
On Complete Filtering of Gravity Modes Through Nonlinear Initialization
Publisher: American Meteorological Society
Abstract: A procedure is outlined which adjusts the initial conditions for any prediction model of a planetary fluid such that no motions of the fluid will evolve with high-frequency, gravity-type time scales despite the model's ...
The ENSO Transition Probabilities
Publisher: American Meteorological Society
Abstract: AbstractENSO is investigated here by considering it as a transition from different states. Transition probability matrices can be defined to describe the evolution of ENSO in this way. Sea surface temperature anomalies are ...
Crucial Experiments in Climate Science
Publisher: American Meteorological Society
Abstract: This article discusses the interplay between computational experiments and scientific advancement in dynamical meteorology and climate dynamics. In doing so, the emphasis is on the dual role of computations in prediction ...
Atmosphere–Ocean Interactions at Strong Couplings in a Simple Model of El Niño
Publisher: American Meteorological Society
Abstract: he understanding of the dynamics of the El Niño?La Niña phenomenon in the tropical Pacific has been the subject of an impressive number of works in the last 20 years. The delayed oscillator theory provides an interpretative ...
Scale Interactions and Atmospheric Predictability: An Updated Perspective
Publisher: American Meteorological Society
Abstract: An examination of the scale interactions in predictability experiments is made using the NCAR Community Climate Model Version 3 (CCM3) at various horizontal resolutions ranging from T42 to T170. Both identical-model and ...
The Reliability of Improvements in Deterministic Short-Range Forecasts in the Presence of Initial State and Modeling Deficiencies
Publisher: American Meteorological Society
Abstract: The reliability of reductions of forecasting error derived from changes in the quality of the initial data or model formulation is considered using a signal-to-noise analysis. Defining the initial data error as the data ...
Uncertainties of Estimates of Inertia–Gravity Energy in the Atmosphere. Part II: Large-Scale Equatorial Waves
Publisher: American Meteorological Society
Abstract: This paper analyzes the spectra and spatiotemporal features of the large-scale inertia-gravity (IG) circulations in four analysis systems in the tropics. Of special interest is the Kelvin wave (KW), which represents between ...
