Abstract: An example of socioeconomic repercussions of the El Niño-Southern Oscillation (ENSO) is examined. Multichannel singular spectrum analysis, a variant of principal component analysis useful in isolating the spatial and ...

Abstract: An analysis of the West European climate over short time scales is performed by means of time series of the 500 mb geopotential height at nine different meteorological stations. The characterization of the dynamics is based ...

Abstract: A shallow water model with realistic topography and idealized zonal wind forcing is used to investigate orographically forced modes in the Martian atmosphere. Locally, the model produces barotropic modes with periods within ...

Abstract: A multivariate ensemble Kalman filter (MvEnKF) implemented on a massively parallel computer architecture has been developed for the Poseidon ocean circulation model and tested with a Pacific basin model configuration. There ...

Abstract: A two-layer shallow-water model with R15 truncation and topographic forcing is used to study intraseasonal variability in the Northern Hemisphere?s (NH?s) extratropical atmosphere. The model?s variability is dominated by ...

Abstract: One of the most difficult aspects of ocean-state estimation is the prescription of the model forecast error covariances. The paucity of ocean observations limits our ability to estimate the covariance structures from ...

Abstract: In practical applications of the ensemble Kalman filter (EnKF) for ocean data assimilation, the computational burden and memory limitations usually require a trade-off between ensemble size and model resolution. This is ...

Abstract: Two global ocean analyses from 1993 to 2001 have been generated by the Global Modeling and Assimilation Office (GMAO) and Geophysical Fluid Dynamics Laboratory (GFDL), as part of the Ocean Data Assimilation for ...
