Coupled Impacts of the Diurnal Cycle of Sea Surface Temperature on the Madden-Julian Oscillation

This study quantifies, from a systematic set of regional ocean-atmosphere coupled model simulations employing various coupling intervals, the effect of subdaily sea surface …

A data assimilative perspective of oceanic mesoscale eddy evolution during VOCALS-REx

An Adjoint-Based Adaptive Ensemble Kalman Filter

A new hybrid ensemble Kalman filter/four-dimensional variational data assimilation (EnKF/4D-VAR) approach is introduced to mitigate background covariance limitations in the EnKF. …

Linear versus Nonlinear Filtering with Scale-Selective Corrections for Balanced Dynamics in a Simple Atmospheric Model

This paper investigates the role of the linear analysis step of the ensemble Kalman filters (EnKF) in disrupting the balanced dynamics in a simple atmospheric model and compares it …

The Madden-Julian Oscillation in CCSM4

This study assesses the ability of the Community Climate System Model, version 4 (CCSM4) to represent the Madden-Julian oscillation (MJO), the dominant mode of intraseasonal …

An Adaptive Approach to Mitigate Background Covariance Limitations in the Ensemble Kalman Filter

A new approach is proposed to address the background covariance limitations arising from undersampled ensembles and unaccounted model errors in the ensemble Kalman filter (EnKF). …
