Baas, Peter (author), Verzijlbergh, R.A. (author), van Dorp, Pim (author), Jonker, H.J.J. (author)As a consequence of the rapid growth of the globally installed offshore wind energy capacity, the size of individual wind farms is increasing. This poses a challenge to models that predict energy production. For instance, the current generation of wake models has mostly been calibrated on existing wind farms of much smaller size. This work...journal article 2023

(author), van der Kooij, H. (author), Mugge, W. (author)Individuals with an upper motor neuron syndrome, e.g., stroke survivors, may have a pathological increase of passive ankle stiffness due to spasticity, that impairs ankle function and activities such as walking. To improve mobility, walking aids such as ankle-foot orthoses and orthopaedic shoes are prescribed. However, these walking aids...journal article 2023

Dirksen, M. (author), Wijnant, Ine (author), Siebesma, A.P. (author), Baas, Peter (author), Theeuwes, Natalie E. (author)In the next few decades climate mitigation efforts will transform the North Sea into one of the most important energy sources. The present wind energy capacity on the North Sea is expected to increase by almost a factor 5 in 2030 and almost a factor 10 in 2050. It is therefore of paramount importance to know how wind farms influence the...report 2022

(author), Spychala, Yvonne T. (author)A revision of the popular equation of Richardson and Zaki (1954a, Transactions of the Institute of Chemical Engineering, 32, 35–53) for the hindered settling of suspensions of non-cohesive particles in fluids is proposed, based on 548 data sets from a broad range of scientific disciplines. The new hindered settling equation enables...journal article 2022

Poppema, D.W. (author), Baas, Andreas C.W. (author), Hulscher, Suzanne J.M.H. (author), Wijnberg, Kathelijne M. (author)Buildings affect aeolian sediment transport and bedform development in sandy environments. Cellular automaton (CA) models have, however, only been used to simulate natural bedform dynamics. This study extends a well-known aeolian CA model to include sediment dynamics around buildings, and uses this model to explore the interaction of building...journal article 2022

(author), De Vries, Hylke (author), Van Meijgaard, Erik (author), Meirink, Jan Fokke (author), Tijm, Sander (author), Van't Veen, Bram (author)The parameterised description of subgrid-scale processes in the clear and cloudy boundary layer has a strong impact on the performance skill in any numerical weather prediction (NWP) or climate model and is still a prime source of uncertainty. Yet, improvement of this parameterised description is hard because operational models are highly...journal article 2022

(author)Wind machines are used in the agricultural sector to prevent or mitigate the adverse effects of night frost in spring.

(author)An overview is given of 50-year Cabauw observations and research on the structure and dynamics of the atmospheric boundary layer. It is shown that over time this research site with its 200-m meteorological tower has grown into an atmospheric observatory with a comprehensive observational program encompassing almost all aspects of the...journal article 2020

(author)High-resolution large-eddy simulations of the Antarctic very stable boundary layer reveal a mechanism for systematic and periodic intermittent bursting. A nonbursting state with a boundary layer height of just 3 m is alternated by a bursting state with a height of ≈5 m. The bursts result from unstable wave growth triggered by a shear-generated...journal article 2020

Izett, J.G. (author), van de Wiel, B.J.H. (author), Baas, P. (author), Schulte, R.B. (author)This poster will be presented at EMS 2019 in Copenhagen. Fog - in particular, the associated reduction is visibility - presents a hazard to airport operations. Although tech- nology has improved to allow greater safety during fog events, protocol still requires more time between aircraft movements, often resulting in significant delays and...poster 2019

(author)Conventional in situ observations of visibility and other meteorological variables are restricted to a limited number of heights near the surface, with the lowest observation often made above 1 m. This can result in missed observations of shallow fog as well as the initial growth stage of thicker fog layers. At the same time, numerical...poster 2019

(author), Bidarra, Rafael (author)While visual impairment is relatively common, most sighted people have no idea of what it is like to live without one of the most heavily utilised senses. We developed the game Loud and Clear in order to have them experience the difficulties of being visually impaired, as well as to put in evidence the abilities blind people have developed,...conference paper 2019

(author)Conventional in situ observations of meteorological variables are restricted to a limited number of levels near the surface, with the lowest observation often made around 1-m height.

(author)In this work we study the dynamics of the surface-based temperature inversion over the Antarctic Plateau during the polar winter. Using 6 years of observations from the French–Italian Antarctic station Concordia at Dome C, we investigate sudden regime transitions in the strength of the near-surface temperature inversion. Here we define “near...journal article 2019

(author), van Baarlen, Peter (author), Kleerebezem, Michiel (author), Hohlbein, Johannes (author)CRISPR-Cas9 is widely used in genomic editing, but the kinetics of target search and its relation to the cellular concentration of Cas9 have remained elusive. Effective target search requires constant screening of the protospacer adjacent motif (PAM) and a 30 ms upper limit for screening was recently found. To further quantify the rapid...journal article 2019

(author)Observations of two typical contrasting weakly stable and very stable boundary layers from the winter at Dome C station, Antarctica, are used as a benchmark for two centimetre-scale-resolution large-eddy simulations. By taking the Antarctic winter, the effects of the diurnal cycle are eliminated, enabling the study of the long-lived steady...journal article 2019

Izett, J.G. (author), van de Wiel, B.J.H. (author), Baas, P. (author), van Hooft, J.A. (author), Schulte, R.B. (author)The Netherlands is characterized by highly variable land use within a small area, and a strong influence of the North Sea on national climate. Devoid of significant topography, it is an excellent location for assessing the relative influence of various factors on fog occurrence in the absence of terrain effects. Using observations from a...journal article 2019
