The Role of the Dynamic Ocean-Atmosphere Interactions in Tropical Seasonal Cycle
Publisher: American Meteorological Society
Abstract: The role of dynamic ocean-atmosphere interactions on the evolution of the tropical seasonal cycle is explored using a simple coupled model. It is shown that the seasonal cycle in the coupled system can be divided into two ...
Coupled Variability and Predictability in a Stochastic Climate Model of the Tropical Atlantic
Publisher: American Meteorological Society
Abstract: The coupled variability and predictability of the tropical Atlantic ocean?atmosphere system were analyzed within the framework of a linear stochastic climate model. Despite the existence of a meridional dipole as the leading ...
Modulation of Small-Scale Superinertial Internal Waves by Near-Inertial Internal Waves
Publisher: American Meteorological Society
Abstract: ynamics of small-scale (<10 km) superinertial internal waves (SSIWs) of intense vertical motion are investigated theoretically and numerically. It is shown that near-inertial internal waves (NIWs) have a pronounced influence ...
A Linear Stability Analysis of Coupled Tropical Atlantic Variability
Publisher: American Meteorological Society
Abstract: A linear stability analysis of an intermediate coupled ocean?atmosphere model reveals that the tropical Atlantic has two types of coupled modes: a meridional mode at the decadal time scale and a zonal mode at the interannual ...
Effect of Oceanic Advection on the Potential Predictability of Sea Surface Temperature
Publisher: American Meteorological Society
Abstract: The effect of oceanic advection on the predictability of sea surface temperature (SST) is investigated in the framework of a linear stochastic model. An analytical solution of a one-dimensional model shows that even though ...
Interaction between Tropical Atlantic Variability and El Niño–Southern Oscillation
Publisher: American Meteorological Society
Abstract: The interaction between tropical Atlantic variability and El Niño?Southern Oscillation (ENSO) is investigated using three ensembles of atmospheric general circulation model integrations. The integrations are forced by ...
Propagation of an Equatorial Kelvin Wave in a Varying Thermocline
Publisher: American Meteorological Society
Abstract: We look at the effect of a slow zonal variation in thermocline depth on the propagation of a finite-amplitude Kelvin wave pulse in a single layer model. Dispersive effects are included by also allowing a weak meridional ...
A Coupled Ocean–Atmosphere Instability of Relevance to the Seasonal Cycle
Publisher: American Meteorological Society
Abstract: Recent observational studies have suggested that interactions between the atmosphere and the ocean play an important role in the pronounced annual cycle of the eastern equatorial Pacific and Atlantic Oceans. The key to ...
Predictable Component Analysis, Canonical Correlation Analysis, and Autoregressive Models
Publisher: American Meteorological Society
Abstract: The purpose of this paper is to clarify the relation between canonical correlation analysis, autoregressive models (also called linear inverse models), and a relatively new statistical technique known as predictable component ...
Linking the Pacific Meridional Mode to ENSO: Coupled Model Analysis
Publisher: American Meteorological Society
Abstract: The occurrence of a boreal spring phenomenon referred to as the Pacific meridional model (MM) is shown to be intimately linked to the development of El Niño?Southern Oscillation (ENSO) in a long simulation of a coupled ...
