Coupled ocean–atmosphere dynamics in the Indian Ocean during 1997–98
TLDR
It is concluded that the 1997–98 anomalies—in spite of the coincidence with the strong El Niño/Southern Oscillation event—may primarily be an expression of internal dynamics, rather than a direct response to external influences. Expand
Ocean forecasting in terrain-following coordinates: Formulation and skill assessment of the Regional Ocean Modeling System
TLDR
The combination of moderate-order spatial approximations, enhanced conservation properties, and quasi-monotone advection produces both more robust and accurate, and less diffusive, solutions than those produced in earlier terrain-following ocean models. Expand
A comprehensive ocean prediction and analysis system based on the tangent linear and adjoint of a regional ocean model
The regional ocean modelling system (ROMS) is a new generation ocean general circulation model that is rapidly gaining favour in the ocean modelling community. The tangent linear and adjoint versions… Expand
Impacts of the 2015–2016 El Niño on the California Current System: Early assessment and comparison to past events
The 2015–2016 El Nino is by some measures one of the strongest on record, comparable to the 1982–1983 and 1997–1998 events that triggered widespread ecosystem change in the northeast Pacific. Here we… Expand
The Regional Ocean Modeling System (ROMS) 4-dimensional variational data assimilation systems Part I - System overview and formulation
TLDR
Several powerful 4D-Var diagnostic tools are discussed, namely computation of posterior errors, eigenvector analysis of the posterior error covariance, observation impact, and observation sensitivity. Expand
Interdecadal modulation of Australian rainfall
Abstract. Interdecadal variability is investigated in a 300 year run of the Parallel Climate Model, a global coupled atmosphere-land-ocean-sea ice model. The model simulates El Niño variability of… Expand
A Theory for the Limitation of ENSO Predictability Due to Stochastic Atmospheric Transients
It is argued that a major fundamental limitation on the predictability of the El Nino-Southern Oscillation phenomenon is provided by the stochastic forcing of the tropical coupled ocean-atmosphere… Expand
Stochastic forcing of ENSO by the intraseasonal oscillation
Abstract Using the ideas of generalized linear stability theory, the authors examine the potential role that tropical variability on synoptic–intraseasonal timescales can play in controlling… Expand
4DVAR data assimilation in the Intra-Americas Sea with the Regional Ocean Modeling System (ROMS)
Abstract We present the background, development, and preparation of a state-of-the-art 4D variational (4DVAR) data assimilation system in the Regional Ocean Modeling System (ROMS) with an application… Expand
The Regional Ocean Modeling System (ROMS) 4-dimensional variational data assimilation systems: Part II – Performance and application to the California Current System
TLDR
A comparison of three approaches to 4D-Var, namely: the primal formulation of the incremental strong constraint approach; the dual formulation “physical-space statistical analysis system”; and the dual formulations indirect representer approach are presented. Expand
