Research & development

Our unique task is the gathering of information about the atmosphere and the subsurface and the translation of that information to risks to the community

    KNMI Global boosts collaboration with developing countries

    The majority of all disasters worldwide are related to (extreme) weather conditions, according to the World Meteorological Organization (WMO). This affects less developed countries most. KNMI has been working with dozens of international partners since its establishment more that 160 years ago. In current times, climate change makes global cooperation even more important. That is why a three-year program, called ‘KNMI-global’, is started in collaboration with the Ministry of Infrastructure and Water Management.
  • Crowdsourced data matches well with official data

    Crowdsourced wind observations can be an invaluable data resource for meteorological studies

    Can citizen scientists help KNMI to improve forecasts and warnings for extreme wind events? The answer is yes according to the new paper by Jieyu Chen, Dr. Kirien Whan, and Dr. Kate Saunders, published in the Quarterly Journal of the Royal Meteorological Society. The research shows that by checking the quality of the data and adjusting for biases there is value in crowdsourced data and that it can be used to complement official observations.

    Calibration of seasonal precipitation forecasts in Java (Indonesia) using bias-corrected precipitation and climate indices

    Seasonal rainfall forecasts help farmers make informed planning decisions about their livelihoods. Skilful rainfall forecasts can improve farming strategies in rain-fed agricultural production. In Indonesia, large-scale modes of climate variability have strong relationships with the seasonal rainfall. This makes them natural candidates for use as potential predictors in a statistical post-processing application. It is not known whether using climate indices as additional predictors in the statistical post-processing of ECMWF Seasonal Forecast System 5 (SEAS5) precipitation can improve skill. Lead author Dian Nur Ratri says "Indices of El Niño and the Indian Ocean Dipole are not needed as extra predictors to improve monthly precipitation forecasts for the first lead month in Java - Indonesia, except for September. However, for longer lead times in September and October, advanced statistical models that use only the climate indices are as skilful as models that use bias-corrected precipitation as the inputs".
