The record‐breaking heat wave of June 2019 in Central Europe
Atmospheric Science Letters, 2020 After being hit by several devastating heat waves in recent years, Europe experienced an exceptionally hot June in 2019 again. This June is the hottest one on record over Central Europe both in a monthly‐mean sense and in terms of the number of extremely

Kinetic Regimes of Hydrogen Absorption in Thin Films
Advanced Functional Materials, EarlyView.Knowledge of the hydrogen incorporation mechanisms in thin layers in relation to the amount absorbed is essential to design coatings and devices compatible with hydrogen‐based technologies. A combination of simultaneous in situ methods gives detailed insight into the hydrogenation of a prototypical hydrogen absorber layer in a time‐dependent manner ...

The Impact of Topographic Steepness on Tidal Dissipation at Bumpy Topography
Fluids, 2017 Breaking internal waves are an important contributor to mixing in the stratified ocean interior. We use two-dimensional, nonhydrostatic numerical simulations to examine the breaking of internal waves generated by tidal flow over sinusoidal bottom ...

Experimental investigation on wave roller area evolution in the surf zone
Applied Ocean ResearchIn the surf zone, breaking waves generate an air-entraining turbulent region ahead of the wave crest, known as the wave roller, which plays a crucial role in nearshore dynamics.

A Non‐Reciprocal Architected Porous Medium
Advanced Functional Materials, EarlyView.ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

The relation between Rossby wave-breaking events and low-level weather systems [PDF]
Weather and Climate DynamicsRossby wave-breaking events describe the last stage in the life cycle of baroclinic atmospheric disturbances. These breaking events can strongly influence large-scale circulation and are also related to weather extremes such as heat waves, blocking, and ...

On the response to ocean surface currents in synthetic aperture radar imagery [PDF]
, 1984 The balance of wave action spectral density for a fixed wave-number is expressed in terms of a new dimensionless function, the degree of saturation, b, and is applied to an analysis of the variations of this quantity (and local spectral level) at wave ...
