Third day of the SBL workshop

30 March 2017 by Secretariaat GRS

The third day at the SBL workshop was divided into three parts: lectures, discussion, and the workshop reception.

The first lecture of the morning provided a background on the implications of radiative forcing on the SBL, including the role of increased greenhouse gas concentrations, suggesting that future modelling approaches must rely on an holistic approach. This was followed by GRS’s Bas van de Wiel who continued on the theme, using an overview of his research and the research of his PhDs over the past years to show how important it is to consider not only the role of turbulence in SBL research, but also the coupling between the air and land surfaces. The final talk of the morning presented the implications of climate change on the SBL, and vice versa: the role of the SBL in a changing climate. An unscheduled talk after lunch then introduced the topic of stable boundary layers over agricultural fields: of significance for water resource management.

The discussion period brought up many interesting points. One common theme was again where the current modelling can best be directed to improve our current state of atmospheric understanding. With so many competing processes – turbulence, atmospheric radiation, land surface coupling, etc. – it is often a challenge to capture the holistic approach described as necessary during the talks, while maintaining an understanding of what is underlying the simulation results. This was addressed nicely on day two by GRS’s Harm Jonker who described the fine balance between reality and understanding: we need both, but often one must be sacrificed for the other.

Leaving the TU Delft campus, the workshop travelled to the Prinsenhof museum in Delft for the formal workshop reception. The Prinsenhof (“Prince’s Court”) was at one point the residence of William of Orange (“The Silent”) who has also been called the “Father of the Nation” for his role in the historical conflicts with the Spanish. He was assassinated there in 1584. The museum is now dedicated to the history and artwork of Delft. Following a visit to the museum, a buffet dinner in the historic building wrapped up the evening.
