Machine learning provides great opportunities for accelerating the representation of physical processes in weather and climate models. Radiative transfer solvers, which deal with the transport of solar and thermal radiation, are often the most costly parametrization in models. Speeding them up is one of the main ambitions of SLOCS [https:
Tropical clouds play an important role in the energy balance of the earth. Clouds reflect solar radiation into space, but also absorb heat that is emitted from the surface of the earth. Clouds therefore play an important role in setting the global atmospheric temperature. In turn, the atmospheric temperature determines
In a new paper [https://rmets.onlinelibrary.wiley.com/doi/10.1002/qj.3441] in Quarterly Journal of Royal Meteorological Society, we present a potential mechanism to explain the observed enhanced cloud formation over Western European forests [https://chiel.ghost.io/2017/01/20/clouds/], such as in Les Landes,
Our project Every ray counts has been granted in the Industrial Doctorates [https://www.nwo.nl/actueel/nieuws/2018/07/zestien-industrial-doctorates-aan-de-slag-in-bedrijfsleven.html] call from NWO [https://www.nwo.nl]. In this project, our group at Wageningen University and Research [https://www.wur.nl/en/Research-Results/Chair-groups/Environmental-Sciences/Meteorology-and-Air-Quality-Group.htm] and
We have published three new papers on land-atmosphere interactions, and the soil moisture-precipitation feedback. The first paper Land-Atmosphere Interactions: The LoCo Perspective [https://journals.ametsoc.org/doi/abs/10.1175/BAMS-D-17-0001.1] is published in BAMS, the American Meteorological Society's flagship journal. The paper presents an overview of the research
The new ECMWF ERA5 [https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era5] data shows the global moisture transport at an unprecedented detail level. For my atmospheric dynamics class, I have downloaded a year of data at the 850 hPa level (just above the boundary layer) and composed a movie.
Clouds reflect incoming solar radiation back into space, but also increase the amount of diffuse radiation that reaches the land surface. Our new study [http://journals.ametsoc.org/doi/10.1175/JHM-D-16-0279.1] (lead author Xabier Pedruzo-Bagazgoitia) shows that thin clouds are beneficial for CO2 assimilation and evapotranspiration, due to
Our new article [http://www.nature.com/articles/ncomms14065] in Nature Communications (lead author Ryan Teuling) presents observational proof of enhanced cloud formation over Western European forests. The related press release of Wageningen University can be found here (in Dutch) [https://www.wur.nl/nl/nieuws/Bossen-bevorderen-wolkenvorming.htm]. The sketch
