Weather4D Lite vs Windy.com

Weather4D Lite is a powerful meteorological application based on atmospheric and oceanic data in GRIB format. It benefits from an interface derived from the “Routing & Navigation” version. View combined weather data displayed in 3D HD layers animated automatically or manually by sliding a finger on the screen. Use GFS model to get started. In addition, over 35 weather and oceanographic models are available with a yearly subscription (in-app purchase). Create your own geographical zones, select the models you need and download only the characteristics that matter to you: data type, resolution, periodicity, file size, etc. GRIB files can be downloaded anywhere through a regular or satellite internet connection. Split the screen (iPad only) to combine and/or compare: navigation and weather, weather and waves or currents, two weather models… The splitted screens can display charts at different scales. Create or import locations, combine them with GRIB forecast models and get a holistic view of the sea conditions. Default Models and Charts ———————————— GFS global forecast model at 0.25 °, 0.5 °, 1 ° and 2 ° resolutions.
