Geosciences, 2022 Groundwater temperature (GWT) is usually measured using screened monitoring wells (MWs). The aim of this study was to investigate whether MWs are suitable for monitoring the effects of large-scale geothermal collector systems (LSCs) on GWT, focusing on ...

Role of convective mixing and evaporative cooling in shallow convection
Journal of Geophysical Research: Atmospheres, 2017 AbstractLarge‐eddy simulations of shallow convection are used to evaluate the role of convective mixing and evaporative cooling in the vertical transport of mass, heat, and moisture in nonprecipitating shallow convection. Evaporative cooling is found to increase mass flux and the magnitude of heat and moisture fluxes, comparing twin large‐eddy ...

Journal of Advances in Modeling Earth Systems, 2019 We use a large‐eddy simulation model with a nested domain configuration (297 and 120 km wide) and an interactive land surface parameterization to simulate the complex population of shallow clouds observed on 30 August 2016 during the Holistic ...

On shallow convective envelopes
The Astrophysical Journal, 1975 Three-dimensionsal (two spatial dimension and time) partial differential equations of mass, momentum, and energy conservation have been integrated numerically by finite difference techniques over a sufficiently long time interval to allow convective motion to develop from computer round-off error. Adiabatic motion is not assumed.

Turbulent dispersion in cloud-topped boundary layers [PDF]
, 2009 Compared to dry boundary layers, dispersion in cloud-topped boundary layers has received less attention. In this LES based numerical study we investigate the dispersion of a passive tracer in the form of Lagrangian particles for four kinds of atmospheric

Nonlinear convective motion in shallow convective envelopes
The Astrophysical Journal, 1976 Numerical solutions of the conservation equation of mass, momentum, and energy in two spatial dimensions and time have been carried out for two shallow convective envelopes (we consider only regions below the photosphere). Cells of a preferred width form and have growth rates larger than cells of other widths.

Nature versus Nurture in Shallow Convection [PDF]
Journal of the Atmospheric Sciences, 2010 Abstract Tracers are used in a large-eddy simulation of shallow convection to show that stochastic entrainment (and not cloud-base properties) determines the fate of convecting parcels. The tracers are used to diagnose the correlations between a parcel’s state above the cloud base and both the parcel’s state at the cloud base and its ...
