MSEAS Probabilistic Analysis and Forecasts for 07 May 0000Z to 15 May 0000Z 2025, Issued 07 May 2025
MSEAS 1/25° Probabilistic Ocean Forecasts (atmospheric and tidally-forced forecasts initialized from downscaled HYCOM)
Physics-balanced stochastic models and ESSE dominant subspace decompositions are used to represent the dominant uncertainties in the initial and boundary conditions for T, S, u, v, w, and eta fields for the HYCOM modeling system fields, in the MSEAS model parameters, in the atmospheric surface forcing flux fields, and in the tidal forcing parameters.

Note: The units of horizontal velocity are cm/s.
