Time‐Multiplexed Reservoir Computing with Quantum‐Dot Lasers: Impact of Charge‐Carrier Scattering Timescale

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Reservoir computing with optical devices offers an energy‐efficient approach for time‐series forecasting. For quantum‐dot lasers with optical self‐feedback, the scattering timescale R into the quantum‐dot levels changes the predictive performance of the reservoir computer.

Land‐surface interactions with the atmosphere over the Iberian Semi‐arid Environment (LIAISE): First mesoscale modelling intercomparison

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Topography of the outer and inner (black line) domains of the simulation (the blue box indicates the region where the probability density functions for Leaf Area Index and wind, temperature and humidity at 2 m above ground are computed). The most common land cover type is also shown over this region for the 3 models to illustrate the differences in ...

The dry‐season low‐level cloud cover over western equatorial Africa: A case study with a mesoscale atmospheric model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The atmospheric mechanisms responsible for the low‐level cloud cover (LCC) over western equatorial Africa in the dry season are poorly studied. This study brings a better understanding of the mechanisms accounting for the diurnal LCC formation and dissipation, and it highlights some potential interactions between local and regional dynamics by using a ...

Analysis of the wind response to resolved versus parametrized turbulent orographic drag in high‐resolution simulations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study analyzes the impact of orographic drag on the lower atmosphere over moderately complex terrain using high‐resolution ICON simulations. Numerical simulations explore the effects of parametrizations over moderately complex terrain near the Perdigao experiment site and the Serra da Estrela mountain range by comparing km‐ and 100‐m‐scale ...

A stochastic differential equation framework for gravity wave parametrisation with testing in an idealised setting

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Parametrisations of unresolved gravity waves used in general circulation models can be made more computationally efficient by introducing a stochastic component to the forcing. Additionally, it is believed that intermittency associated with a stochastic parametrisation could be tuned to resemble the intermittency of observed gravity wave sources to ...

A conservative numerical scheme for the multilayer shallow‐water equations on unstructured meshes

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving scheme is derived for the multilayer shallow water model, making use of the direct connection between energy conservation and the skew symmetry of the Poisson bracket for the model. A new mechanism is proposed to prevent layer interface outcropping.

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion

Journal of Field Robotics, EarlyView.
ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

Flash flood disaster risk evaluation based on geographic detector and interval number ranking method

River, EarlyView.
Abstract Among natural disasters, flash floods are the most destructive events, causing significant damage to the economy and posing a serious threat to human life and property. Comprehensive risk assessment of these sudden floods is a key strategy to mitigate their impact. Accurate analysis of flash flood hazards can greatly enhance prevention efforts
