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.
A tropical cyclone forecast model is a computer program that uses meteorological data to forecast aspects of the future state of tropical cyclones. There are three types of models: statistical, dynamical, or combined statistical-dynamic. [ 1 ]
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).

Map shows the forecast path for Tropical Storm Sara as of Nov. 14, 2024. ... Forecast models take in the current environmental factors along with historical data to compute "spaghetti plots" of ...
The cone represents the probable position of a tropical cyclone's circulation center, and is made by drawing a set of circles centered at each forecast point—12, 24, 36, 48, and 72 hours for a three-day forecast, as well as 96 and 120 hours for a five-day forecast. The radius of each circle is equal to encompass two-thirds of the historical ...
HWRF 96-hour (4-day) forecast for Hurricane Katrina heading for New Orleans in 2005. The Hurricane Weather Research and Forecasting (HWRF) model is a specialized version of the weather research and forecasting model and is used to forecast the track and intensity of tropical cyclones.
