Apr 29, 2020 · Cloud-resolving simulations using the Weather Research and Forecasting with Chemistry model combined with aircraft measurements were performed to understand the effect of entrainment, scavenging efficiency (SE), and ice physics processes on these trace gases.

May 14, 2019 · Dissipating waves contribute to vertical mixing of the atmosphere, alter molecular and eddy diffusion, and induce chemical transport of reactive species. These processes induce strong vertical transport of atmospheric constituents …

Dec 21, 2018 · In this study, we investigate the asymmetry of vertical motions by analyzing cyclones and anticyclones in observational data and climate change simulations. We show that the asymmetry intensifies in a warmer climate, as downward motions weaken and upward motions slightly intensify.

We explore the range of uncertainty in estimates of the indirect aerosol effects attributable to the choice of parameterisation of the subgrid-scale variability of vertical velocity in HadGEM-UKCA.

Jul 5, 2017 · The law of conservation of linear momentum is applied to surface gas exchanges, employing scale analysis to diagnose the vertical velocity (w) in the boundary layer.

Feb 1, 2022 · Vertical velocities and microphysical processes within deep convection are intricately linked, having wide-ranging impacts on water and mass vertical transport, severe weather, extreme precipitation, and the global circulation.

Detailed case studies are examined, focusing on three levels within the cloud layer, where wavelet and power spectral analyses are applied to characterize the dominant temporal and horizontal scales associated with cloud-generated vertical motions.

Nov 28, 2022 · Vertical movements (or vertical wind) are one of the components of the general circulation of the atmosphere. This type of motion is important for the dynamics, electrodynamics, plasma physics, and chemistry of the Earth’s lower ionosphere.

Nov 24, 2015 · Vertical chemical transport occurs when the density fluctuations of a species, caused by perturbations of its chemistry, are strongly correlated with the vertical wind fluctuations. Chemical transport can exceed dynamical and eddy transport of chemically active species.

Jul 28, 2017 · In this work we develop a method, using ultra high resolution global simulations to directly calculate the global distribution of subgrid vertical velocity affecting cirrus formation.
