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

    Estimating wind gusts during severe wind conditions

    Extreme windstorms are the most important natural hazards affecting Europe. Losses are not primarily caused by the sustained wind speed but by the gusts, i.e., the maxima of the wind speed during a few seconds.

    Statistical Post-Processing workshop - TU Delft 2019

    Researchers from KNMI, TU Delft, WUR, VU, and UU came together on Thursday 7 November at the Delft Institute of Applied Mathematics at TU Delft, hosted by Prof. dr. ir. Geurt Jongbloed, who also attended the workshop. They discussed the state of statistical post-processing research in The Netherlands. The researchers all work in close collaboration with KNMI to improve weather forecasts at a variety of scales. These collaborations between a government research organisation and universities that have different research focuses, from statistical to domain knowledge, are valuable as they allow the contribution from different perspectives to a common research question.

    Validation of Stratification-Driven Phytoplankton Biomass and Nutrient Concentrations in the Northeast Atlantic Ocean as Simulated by EC-Earth

    The physical and biochemistry model EC-Earth-NEMO-PISCES is validated against physical and biological observations in the North-Atlantic (the Stratiphyt transect, running from the Azores to Iceland). While in the southern part of this transect the agreement is very good, the northern section clearly shows a mismatch in phytoplankton spring bloom that could be related to biases in simulated mixed layer depths and salinities. A second simulation with more accurate vertical ocean mixing showed improved springtime mixed layer depths, phytoplankton dynamics and nutrient distributions in the subpolar North Atlantic. This highlights the sensitivity of phytoplankton behaviour to increased future meltwater input into the North Atlantic resulting from e.g. melting of the Greenland Ice Sheet. This paper also demonstrates the intricate links between physics and biology, and the need to validate the coupled system in Earth System Models.
