Nowcasting of High-Intensity Rainfall for Urban Applications in the Netherlands
Radar rainfall nowcasting has mostly been applied to relatively large (often rural) domains (e.g., river basins), although rainfall nowcasting in small urban areas is expected to be more challenging. Here, we selected 80 events with high rainfall intensiti ...
Amer Meteorological Soc2024Roger F. Harrington and the Method of Moments: Part 2: Electrodynamics
The method of moments (MOM), as introduced by Roger F. Harrington more than 50 years ago, is reviewed in the context of the classic potential integral equation (IE) formulations applied to both electrostatic (part 1) and electrodynamic or full-wave problem ...
Piscataway2024Roger F. Harrington and the Method of Moments: Part 1: Electrostatics
The method of moments (MOM), as introduced by R. F. Harrington more than 50 years ago, is reviewed in the context of the classic potential integral equation (PIE) formulations applied to both electrostatic (part 1) and electrodynamic, or full-wave, problem ...
Piscataway2024An Elliptic Local Problem With Exponential Decay Of The Resonance Error For Numerical Homogenization
Assyr Abdulle, Doghonay Arjmand, Edoardo Paganoni
Numerical multiscale methods usually rely on some coupling between a macroscopic and a microscopic model. The macroscopic model is incomplete as effective quantities, such as the homogenized material coefficients or fluxes, are missing in the model. These ...
SIAM PUBLICATIONS2023Improved extended-range prediction of persistent stratospheric perturbations using machine learning
On average every 2 years, the stratospheric polar vortex exhibits extreme perturbations known as sudden stratospheric warmings (SSWs). The impact of these events is not limited to the stratosphere: but they can also influence the weather at the surface of ...
Gottingen2023Augmenting the performance of impoverished sensor networks using machine learning and time reversal: Application to lightning nowcasting and location
Lightning is formed in the atmosphere through the combination of intricate dynamic and microphysical processes. Mainly due to this complexity, attempts to solve the important problem of lightning prediction have generally failed to yield accurate results. ...
EPFL2021Intercomparison of Large-Eddy Simulations of the Antarctic Boundary Layer for Very Stable Stratification
Etienne Gabriel Henri Vignon, Jing Huang
In polar regions, where the boundary layer is often stably stratified, atmospheric models produce large biases depending on the boundary-layer parametrizations and the parametrization of the exchange of energy at the surface. This model intercomparison foc ...
SPRINGER2020A mechanistic understanding of adhesive wear
We discuss recent advances in developing a fundamental, mechanistic, understanding of the evolution of surface roughness of solids during dry sliding. The time evolution of surface roughness is little understood although it crucially impacts friction and w ...
2020LMDZ6A: The Atmospheric Component of the IPSL Climate Model With Improved and Better Tuned Physics
This study presents the version of the LMDZ global atmospheric model used as the atmospheric component of the Institut Pierre Simon Laplace coupled model (IPSL-CM6A-LR) to contribute to the 6th phase of the international Coupled Model Intercomparison Proje ...
