But there are always others that can usefully complement the standard offerings of these applications. Read more …
Predict storms with Weather4D
In Weather4D (all versions) most weather models provide a data called CAPE.
Convective Available Potential Energy, in French : Energie potentielle de convection disponible. Behind this obscure acronym hides a powerful storm forecasting tool. CAPE is measured in Joules per kilogram of air (J/Kg) and defines the vertical buoyancy energy of a hot air particle in a colder atmosphere. In other words, vertical acceleration of the air particle will be directly related to this energy measurement. Read more …

Sea state : interpret wave patterns
In Weather4D, as generally in other applications, sea state forecasts are described by ocean models. The most used is the model WW3 (Wave Watch III), published by FNMOC (Fleet Numerical Meteorology and Oceanography Center) of the US Navy, with a global model due to 7 days and resolution 1° (60NM), and a Europe model to 3 days and resolution 0.2° (12NM). Météo-France publish the models MFAUM (Wave Assimilated Model) coupled with the ARPEGE and AROME weather models with three resolutions : Global at 0.5° (30NM), Europe at 0.1° (6NM), France at 0.025° (1,5NM) with variable deadlines (¹).
