Share GRIB files with Air Share [Update]
You are more likely to have adopted the Iridium GO! for its easy way to request GRIB files, directly from Weather4D and some other applications. But some also want to transfer these files to PC to import them into Windows software (as you know, nobody is perfect !). An easy solution is available : the messaging app Air Share, compatible iOS/iPadOS (¹). [Update 30 March 2022] Warning : the app has changed its ID code on the AppStore. Read more …
ECMWF weather data soon open to the public [3rd part]
Trafalgar Hit for the flagship of European meteorology, despite Brexit and contrary to what had been planned (¹), the European Center for Medium-Range Weather Forecast will stay in England ! Even better, a new headquarter for ECMWF to be fully funded by the UK government through the Department for Business, Energy and Industrial Strategy. Proof that the British have gone all out to keep this European scientific center in Reading (²). Read more …
Are GRIB files consistently optimistic ?
This question has been asked regularly, but until now I had never wanted to publicly give my opinion on the subject so as not to offend anyone and especially not to create unnecessary controversy. But by dint of doing it during my training, why not express it openly ?

Alternative weather models [Update]
[Updated 29 July 2022]
For several years, forecast files in GRIB format have been widely used in meteorological applications.. The majority of forecast models have been made freely available by the meteorological services, all countries included. Applications like XyGrib, LuckGrib, SailGrib, Weather4D and other, offer a selection of atmospheric and oceanic models, up to 25 weather models and 15 waves and currents models for Weather4D, more than thirty models with LuckGrib, in example. But there are always others that can usefully complement the standard offerings of these applications.. Read more …
Predict thunderstorms with Weather4D
In Weather4D (all versions) most weather models provide a data calledCAPE.
Convective Available Potential Energy, in French : Energie potentielle de convection disponible. Behind this abstruse acronym hides a powerful tool for forecasting thunderstorms. The CAPE is measured in joules per kilogram of air (J / Kg) and defines the vertical thrust 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 …
