Sensitivity of flower trade‐wind cloud organisation to mesoscale atmospheric heterogeneities

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Trade‐wind cloud organisation is insensitive to dynamical and thermal heterogeneities but very sensitive to humidity mesoscale heterogeneities, especially in the cloud layer, where they form moist patches, and not in the sub‐cloud layer. Clouds and rain develop in moist patches, then cold pools develop progressively, initiating mesoscale circulations ...

Enhanced Particulate Organic Carbon Export at Eddy Edges in the Oligotrophic Western North Pacific Ocean. [PDF]

PLoS ONE, 2015
Mesoscale eddies in the subtropical oligotrophic ocean are ubiquitous and play an important role in nutrient supply and oceanic primary production.

Tropical cyclone intensity modulated by the oceanic eddies in the Bay of Bengal

Oceanologia, 2022
The Bay of Bengal, an affluent region for mesoscale oceanic eddies, is also home to devastating tropical cyclones. The intensity modulation of two cyclones, Phailin (2013) and Fani (2019), in the Bay of Bengal by the oceanic eddies is studied.

Parameterizing mesoscale eddy buoyancy transport over sloping topography

Journal of Advances in Modeling Earth Systems, 2023
Most of the ocean’s kinetic energy is contained within the mesoscale eddy field. Models that do not resolve these eddies tend to parameterize their impacts such that the parameterized transport of buoyancy and tracers reduces the large-scale available potential energy and spreads tracers.

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

Quarterly 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

Dissipative inertial transport patterns near coherent Lagrangian eddies in the ocean

, 2015
Recent developments in dynamical systems theory have revealed long-lived and coherent Lagrangian (i.e., material) eddies in incompressible, satellite-derived surface ocean velocity fields.

Oceanic stochastic parametrizations in a seasonal forecast system [PDF]

, 2010
We study the impact of three stochastic parametrizations in the ocean component of a coupled model, on forecast reliability over seasonal timescales. The relative impacts of these schemes upon the ocean mean state and ensemble spread are analyzed.

Modulation of North Atlantic atmospheric rivers by the Gulf Stream

Quarterly 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.

A Thermal Plume Model for the Martian Convective Boundary Layer [PDF]

, 2013
The Martian Planetary Boundary Layer [PBL] is a crucial component of the Martian climate system. Global Climate Models [GCMs] and Mesoscale Models [MMs] lack the resolution to predict PBL mixing which is therefore parameterized.

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

Quarterly 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.
