We just published our own app with meteorological forecasts for the Iberian Peninsula and the Balearic Islands. The forecasts consist on hourly data for the next 48 hours, and are produced with the WRF model (nested into the 12UTC run of the WRF model) with a horizontal resolution of 8 km. Forecasts are available for the following variables:
- Temperature
- Precipitation
- Wind speed and direction
- Humidity
- Cloud cover
- Snow
- Apparent temperature, which is defined as the temperature perceived by a person standing outdoor, taken into account the air temperature, the humidity and the wind speed.
These forecasts are generic, and no correction techniques are applied to the model output, except a simple topography correction (see A simple height-based correction for temperature downscaling in complex terrain). Consequently, there can be systematic biases in some locations, especially in areas with complex topography. Also, is important to note that the forecast of some phenomena is intrinsically uncertain. For example, it is not possible to foresee the time and place where a summer thunderstorm will happen. In order to illustrate the accuracy and limitations of a forecast at this resolution, we implemented a validation section, where the recent forecasts can be compared with observed data, using the observation network of AEMET. This evaluation is a novelty, as it is not available in other similar apps.
The app is available for Android devices, and soon will be available for iOS too. It is offered free of change with no ads, and pretends to illustrate the reach and limitations of a mid-range resolution forecasts (8 km), not very high for actual standards. If you are interested in more customized forecasts, with higher resolution, please see our products.
