Simulating the year to minute wind spectrum with mesoscale‐coupled large‐eddy simulations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We coupled a large‐eddy simulation (resolution 50 m) to a mesoscale model (resolution 2 km), which takes boundary conditions from the ERA5 reanalysis. When using a large enough mesoscale domain (𝒪(1000 km)), the simulation setup can reproduce the observed temporal wind spectrum reasonably at all scales between one year and one minute. Furthermore, such

Modulation of North Atlantic atmospheric rivers by the Gulf Stream

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Gulf Stream ocean variability plays a key role in modulating atmospheric river (AR) activity over the North Atlantic during winter and spring at monthly time‐scales. Increased ocean heat transport and mesoscale activity in the Gulf Stream are linked to northward shifts in ARs, while stronger surface heat fluxes drive ARs southward.

Parameter investigation for urban surface‐energy balance: A large‐eddy simulation study

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Large eddy simulation modelling is used to investigate the variation in surface‐energy balance (SEB) across an ensemble of morphometrically identical urban geometries. The geometries have the same plan‐area fraction, vegetated fraction, and frontal‐area index, but are unique in terms of building and green‐space layout.

A review of the FATIMA Yellow Sea field campaign research

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The FATIMA marine fog project took place over the Sable Island region of eastern Canada (summer 2022) and the Yellow Sea of the Republic of Korea (ROK, summer 2023). Its goals are to improve marine fog monitoring and forecasting. Instrumented multiple research vessels, aircraft, tethered balloon and autonomous systems, ocean observation sites, and ...

Microphysical chemistry of fog–aerosol interactions over the northwest Atlantic Ocean during Fatima 2022

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Fifteen size‐resolved aerosol samples collected during marine fog, with adjacent ambient observations, show that coarse sea salt aerosol is rapidly grown and lost in the northwest North Atlantic Ocean except when subject to extreme winds. The persistence of fog in the absence of sea salt is determined by available fine‐mode aerosol, where greater ...

Large Eddy Simulation

2016
The behaviour of fluids can be described by the well-known mathematical model known as the Navier-Stokes equations. The original equations include formulations for the conservation of momentum, energy and mass, therefore leading to three momentum equations, one energy equation and one continuity equation. The form presented below is a simplification of

Large Eddy Simulation

2011
At high Reynolds number the fluid velocity is exponentially sensitive to perturbations of the problem data. This sensitivity, however, is not uniform. The large structures (large eddies) evolve deterministically and are thus not sensitive [BFG02]. The small eddies are sensitive because they have a random character.

Large-eddy simulations

International Journal of Computational Fluid Dynamics, 2010
Abstract The large-eddy-simulation technique is introduced. The mathematical formulation is presented, and several examples are discussed. Some issues related to the resolution of the wall layer are reviewed. Challenges and possible future developments are addressed.
