The Earth’s climate is changing, due to global warming, impacting the ocean circulation around the world. As the ocean circulation distributes large amounts of energy around the world, this can alter climate drastically if changed. The Atlantic Meridional Overturning Circulation (AMOC) is a fundamental ocean component to comprehend climate...

This thesis investigates the implementation of three-dimensional nudging into large-eddy simulation (LES) to assimilate observed atmospheric data into an LES model. 3D-nudging 'pushes' the thermodynamic fields in a simulation towards the desired observed fields. The aim is to test if such a method is useful in improving solar forecasts of...

In this research, a model to simulate the urban surface energy balance (SEB) model is developed. Urban geometry plays an important role in the SEB and the resulting surface temperatures. A well-known effect of how building geometry affects radiation is shadowing and trapping of LW radiation. The goal of the energy balance model is to quantify...

In the atmospheric boundary layer, when surface heat flux is small and mean wind shear is strong, horizontal convective rolls that are elongated along the wind shear are formed. This study attempts to explain the asymmetry of rolls in terms of turbulence using large-eddy simulations. A pressure gradient in the north-south y direction is applied,...

We aim to make solar power forecasts using regression for grid optimization. We forecast from 1 to 6 hours ahead. The forecasts prove to be accurate with a skill score of 20% compared to persistence for a lead time of one hour.

As the intensity and frequency of urban heat wave increases in Europe, evaporative cooling from watering pavements has been considered as a promising strategy to regulate urban temperature. The aim of this research is to include evaporative cooling modelling and enhance the surface temperature model SURF-TEMP, which is in development at the...

In this thesis, the foundations are explored for establishing two-dimensional depth-integrated morphodynamical equilibria for a long embayment with two tidal inlets connected to the open sea. Governing water motion, suspended sediment transport and bed evolution equations had to be rederived from the underlying balances, where the tidal inlets...

Er wordt geschat dat 80% van al het zuurstof op aarde geproduceerd wordt door fytoplankton. Dit is een soort eencellige plant die voorkomen in wateren over de hele wereld. Deze kleine planten worden voornamelijk gegeten door zoöplankton, kleine organismen bestaand uit meestal enkele cellen. Afsterving of overbevolking van fytoplankton heeft ook...

A freshening of the boundary current (Labrador current and West Greenland Current) supresses deep convection in the Labrador Sea. Furthermore, the fresher water contributes to the ``strength'' of Irminger Rings and increases their life time. This leads to a larger spread of high EKE into the interior of the Labrador Sea and confines the deep...

Nitrogen dioxide (NO2) is one of the nitrogen oxides (NOx) pollutants. Not only the NO2 itself is toxic to human health, but also the precursors of a number of hazardous secondary air pollutants, such as nitric acid, tropospheric ozone and nitrate component of particulate matters. Besides, NO2 is also an essential substances involving in ozone...

In this study the prediction of stratocumulus occurrence by the Large-Eddy Simulation model DALES was investigated. The performance of DALES was compared with that of the large-scale weather model RACMO. A method was developed which can consistently initialise the model by assimilation of observations in addition to large-scale weather model...

Using the Dutch Atmospheric Large-Eddy Simulation model (DALES) the atmosphere in both a pure radiative and a radiative-convective equilibrium is investigated. These simulations are performed on a domain which top is located at 30 kilometres. This high altitude requires some modifications of the radiative transfer code used in DALES. The effects...

Johnstone and Coleman (2012) were among the first to opt the idea of wind farms with mixed tower heights and predicted an increased power production due to the decrease of losses to TKE production from the mean kinetic energy balance. In the current study, the performance of infinite wind farms with alternating tower heights imposed by a...

For this study, Urban Heat Island (UHI) consequential urban atmospheric thermally stratified buoyancy influences were investigated, utilising an in-house Computational Fluid Dynamic (CFD) modelling code, SARA3DCLIMAT. The code is based on transient-Reynolds Averaged Navier-Stokes (T-RANS) and hybrid Large Eddy Simulation (LES)/T-RANS methods,...

The importance of moisture feedback between continental precipitation and evaporation, referred to as moisture recycling, is still under debate. Most of the research in the past focused on the contribution of recycling to precipitation within a certain region only. This paper clearly distinguishes between different definitions of moisture...
