How does windy make an offline weather forecast? and where is it?
suppose im here because of that specific feature only but I cant really find it anywhere but if its an actual feature heres my question: mainly on how did they able to send data and information in offline mode, im really curious and I hope I can get an explanation on it
HI @Akiiiiiiiiiiiiii, at this moment, we don't have any offline functionality.
As @Ondřej-Šutera said, Windy does not offer the possibility to receive weather forecast when you are offline.
At sea the apps which do it are generally sending the numerical weather data via a narrow band satellite receiver e.g. Iridium Go or similar. This data in light format is GRIB files which need a viewer software to get simplified weather maps.
Windy, like many weather forecasting websites and applications, likely uses a combination of historical weather data and numerical weather prediction models to generate forecasts for specific locations. Numerical weather prediction models use complex algorithms to simulate the behavior of the atmosphere based on a set of initial conditions, such as temperature, pressure, and wind speed. These models take into account a wide range of physical processes, such as the movement of air masses, the transfer of heat and moisture, and the effects of topography. The forecasts generated by these models are then adjusted using historical weather data and other observations to improve their accuracy. Some weather apps or websites may also use weather radar and satellite images to provide additional information about current weather conditions and to make predictions about future weather patterns.
To make offline weather forecast, the application will have to download the forecast data for the area of interest and store in the device, so that the user can access them even if the device is not connected to the internet.
Two remarks Mate, to your theoretical discourse:
- Windy does NOT use historical data to make weather forecasts. Windy only shows raw forecasts from major weather models and does not adjust them with historical data or with additional observations. If radar or satellite data is involved, it is integrated by the weather model itself and not by Windy.
- The way you describe offline weather forecast does not provide UPDATED data. When the internet connection is off, the only way to get updated weather forecasts is the method explained here above.
