The meteoblue weather forecasting system is fully automatic. It is based on the NMM (Numerical Meso-Scale Modelling) technology, which calculates forecasts for complete "domains" (areas) within a detailed spatial resolution (meso-scale = 20-1 km; micro-scale = < 1 km) for a total of 55 atmosphere layers simultaneously. Basics are described under science
meteoblue models produce approximately 400'000 forecast areas places in Europe, and another 500'000 places in South America and Africa. The initialisation and the forecast in other regions are based on GFS in 1° resolution or 0.5° where available.
For local (p☼int)
forecasts, proprietary downscaling methods are used, which take into account factors such as the atmospheric layers, fluid dynamics, and exposition.
The model accuracy
is superior to the classical station-based forecast and to other models. meteoblue models can therefore be used in areas where the economical use of weather forecasts was so far not possible, e.g. surface water discharge forecasts, weather route planning, solar energy prognosis as well as for local wind or precipitation forecast in mountainous and remote areas.
meteoblue calculates own meteorological previsions models every day. We update predictions usually 2 times per day, in Europe 4x
. Higher frequency will not increase forecast accuracy, unless more frequent detailed measurement data ara available for initialisation. Typically, only 1-3 hours forecasts (nowcast) improve by more frequent updates.
