WRF and ROMS/TOMS Coupling Summer Supercell Test Updraft cells (yellow/white) drove strong convergent surface winds (white arrows) resulting in strong (2-3 m/s) surface currents. Surface height (color slice) variations of a half-meter over 20 km were observed, and waves propagate along the thermocline (shown in blue). (C. Moore)

* Inverse Modeling in the California Current System a) * Deterministic fits of the physical (and biological) observations (inverse method strategy :allows the models to reach a dynamical consistent state, analysis of dynamical balances, eddies, transports …) Southern California Model Grid San Francisco * Data Assimilation (assimilation to combine different data sources: CTD’s, ADCP, Satellite and others … to aid general studies of the California Current System) Pt. Conception San Diego b) * [m] Predictability of physics and biology (dynamical theory :investigate the limits of predictability timescale and the dynamical basis for predictability) c) Ecosystem response to physical forcing (ecosystem model analysis : to what degree is the biology dependent on the physics? What level of compexity is needed in the ecosystem?) CalCOFI data array(50 years seasonal in situ obs.) d) Impacts of climate variability : El Niño (sensitivity model experiments : investigate the system response to changes of the mean state (eg. El Niños, Climate shifts …)
