  • About the Edition

    Studies of convection in geophysical flows constitute an advanced and rapidly developing area of research that is relevant to problems of the natural environment. During the last decade, significant progress has been achieved in the field as a result of both experimental studies and numerical modelling. This led to the principal revision of the widely held view on buoyancy-driven turbulent flows comprising an organised mean component with superimposed chaotic turbulence. An intermediate type of motion, represented by coherent structures, has been found to play a key role in geophysical boundary layers and in larger scale atmospheric and hydrospheric circulations driven by buoyant forcing. New aspects of the interaction between convective motions and rotation have recently been discovered and investigated. Extensive experimental data have also been collected on the role of convection in cloud dynamics and microphysics. New theoretical concepts and approaches have been outlined regarding scaling and parameterization of physical processes in buoyancy-driven geophysical flows. The book summarizes interdisciplinary studies of buoyancy effects in different media (atmosphere and hydrosphere) over a wide range of scales (small scale phenomena in unstably stratified and convectively mixed layers to deep convection in the atmosphere and ocean), by different research methods (field measurements, laboratory simulations, numerical modelling), and within a variety of application areas (dispersion of pollutants, weather forecasting, hazardous phenomena associated with buoyant forcing).

    BUOYANCY-DRIVEN FLOWS Buoyancy is one of the main forces driving flows on our planet, especially in the oceans and atmosphere. These flows range from buoyant coastal currents to dense overflows in the ocean, and from avalanches to volcanic pyroclastic flows on the Earth’s surface.

    Oct 22,  · However, they are readily entrained by sublithospheric small‐scale convection to reach the base of lithosphere, sustaining mantle melting and intraplate volcanism. Water contents of > wt.‐% in a ≥ 60‐km‐thick layer atop the slab are sufficient for an early (Author: Xiaogang Long, Xiaogang Long, Maxim D. Ballmer, Maxim D. Ballmer, Antonio M.‐C. Córdoba, Chun‐Feng L. Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock ().Convection includes sub-mechanisms of advection (directional bulk-flow transfer of heat), and diffusion (non-directional transfer of .

Jul 01,  · Prime examples of such flows are mantle convection, atmospheric flows, solar convection, dynamo process, heat exchangers, airships and hot air balloons. In this book we present fundamentals and applications of thermal convection and stratified flows.

Instabilities are present in all natural fluids from rivers to atmospheres. This book considers the physical processes that generate instability. Part I describes the normal mode instabilities most important in geophysical applications, including convection, shear instability and baroclinic forabetterchicago.com by: 6.

In the vicinity of h we isolate a thin layer with the depth δh. Then we approximate the velocity gradient across this layer with Δuh/δ, and the increment of the. x component of momentum flux with the linear function Δu Dh Dt hz h.

− δ, multiply them, and carry out the integration over the layer δh. Geophysical boundary layers are considered, taking into account the atmospheric boundary layer, the ocean surface layer, and aspects of pollutant plume dispersion in the surface layer.

It is pointed out that the first kilometer of the atmosphere approximates to a boundary layer, whose external stream is the high-altitude wind and whose study is.

Today, buoyant convection in geophysical flows is an advanced and still-developing area of research relevant to problems of the natural environment. During the last decade, significant progress has been achieved through experimental studies, both in nature and in the laboratory, and through large-eddy and direct numerical simulations.

Book description. The phenomena treated in this book all depend on the action of gravity on small density differences in a non-rotating fluid. The author gives a connected account of the various motions which can be driven or influenced by buoyancy forces in a stratified fluid, including internal waves, turbulent shear flows and buoyant forabetterchicago.com: J.

Turner. An intriguing variety of vortex structures arise during buoyant convection, especially in the presence of background stratification and rotation. These vortices play an important role in environmental fluid motions, bearing upon small-scale turbulence to planetary-scale forabetterchicago.com by: [5] To study buoyant currents with convective dissolution, we employ an analog‐fluid system in which water plays the role of the buoyant CO 2 and propylene glycol (PG) plays the role of the denser and more viscous ambient groundwater [Backhaus et al., ].

Shallow cumulus convection plays a crucial role in determining the vertical thermodynamic structure of the atmosphere and influences the large-scale circulation significantly in both tropics and mid-latitudes.

This is most clearly demonstrated in the Hadley circulation over the tropical oceans, such as schematically illustrated in forabetterchicago.com by: CBL flow regimes with combined buoyant and shear forcings can be investigated.
