The Global Environmental Multiscale Model (GEM), often known as the CMC model in North America, is an integrated forecasting and data assimilation system developed in the Recherche en Prévision Numérique (RPN), Meteorological Research Branch (MRB), and the Canadian Meteorological Centre (CMC).
The GME was replaced by the ICON (Icosahedral Nonhydrostatic) model on 20 January 2015. ICON uses the same icosahedral approach, but has a higher resolution at 13 km. [2] [3] Various unofficial websites distribute ICON model data, including Tropical Tidbits and Windy. In 2021 ICON-D2 and ICON-EU models were released.
The first dynamical hurricane track forecast model, the Sanders Barotropic Tropical Cyclone Track Prediction Model (SANBAR), [9] was introduced in 1970 and was used by the National Hurricane Center as part of its operational track guidance through 1989. It was based on a simplified set of atmospheric dynamical equations (the equivalent ...
