A System Simulation Approach to Ensemble Prediction
TL;DR: A method for producing error statistics from a representative ensemble of forecast states at the appropriate forecast time is proposed and examined and an attempt is made to simulate the process of error growth in a forecast model.

Implementation of the Semi-Lagrangian Method in a High-Resolution Version of the ECMWF Forecast Model
Harold Ritchie,Clive Temperton,Adrian Simmons,Mariano Hortal,Terry Davies,David Dent,Mats Hamrud +6 more
TL;DR: In this paper, the semi-Lagrangian method was applied to a high-resolution version of the ECMWF forecast model and its performance was evaluated on a set of 12 independent cases.

Modeling the formation and circulation processes of water masses and sea ice in the Gulf of St. Lawrence, Canada
TL;DR: In this paper, the seasonal cycle of water masses and sea ice in the Gulf of St. Lawrence is examined using a three-dimensional coastal ice-ocean model with realistic tidal, atmospheric, hydrologic, and oceanic forcing.

Ronald E. Stewart,H. G. Leighton,Philip Marsh,G. W. K. Moore,Harold Ritchie,Wayne R. Rouse,Eric D. Soulis,G. S. Strong,R. W. Crawford,B. Kochtubajda +9 more
TL;DR: In this article, the authors present the overall objectives and scope of the MAGS (Mackenzie GEWEX Study), which is focusing on understanding and modeling the fluxes and reservoirs governing the flow of water and energy into and through the climate system of the Mackenzie River Basin.

Seasonal predictions based on two dynamical models
Jacques Derome,Gilbert Brunet,André Plante,Normand Gagnon,George J. Boer,Francis W. Zwiers,Steven J. Lambert,Jian Sheng,Harold Ritchie +8 more
TL;DR: In this article, two dynamical models are used to perform a series of seasonal predictions, referred to as GCM2 and SEF, for climate studies and numerical weather prediction, respectively.
