Changing Spatial Patterns of Deep Convection in the Subpolar North Atlantic
Journal of Geophysical Research: Oceans, 2021 Deep convection and associated deep water formation are key processes for climate variability, since they impact the oceanic uptake of heat and trace gases and alter the structure and strength of the global overturning circulation.

Geophysics of Deep Convection and Deep Water Formation in Oceans [PDF]
, 1991 Abstract An important task for geophysicists studying deep convection and deep water formation in the ocean is to investigate various physical mechanisms generating vertical circulation. Two major types of such mechanisms are available so far, namely, thermodynamical instability, which generates convection and mixing due largely to surface buoyancy ...

Abstract : Our long-term objective is to understand how deep convection, induced by strong buoyancy forcing at the ocean surface, influences the ocean circulation through convective plumes and geostrophic eddies.

Monitoring deep convection and convective overshooting with METEOSAT
Advances in Space Research, 1997Abstract Simultaneous observations of deep convective clouds in the infrared window (IR: 10.5 – 12.5 μm) and the water vapour absorption band (WV: 5.7 – 7.1 μm) from METEOSAT reveal that the equivalent brightness temperature in the WV channel can be larger than in the IR channel by as much as 6 – 8 K.

Modeling ocean deep convection
Ocean Modelling, 2004Abstract The goal of this study is to assess models for Deep Convection with special emphasis on their use in coarse resolution ocean general circulation models . A model for deep convection must contain both vertical transport and lateral advection by mesoscale eddies generated by baroclinic instabilities.

Steady Convection in Deep Compressible Layers
Astrophysics and Space Science, 1998It is known from the literature that the standard mixing-length model of convection traditionally used in astrophysics is based on an analogy with the kinetic theory of gases. Simulations of steady convection do not find eddies of order of local scale height, but rather single cells extending over several scale heights from top to bottom of the layer ...

The Parameterization of Deep Convection
1997Insights into the parameterization of convection from two decades of diagnostic studies are reviewed. The life cycle of a convective mesosystem mass flux is described using day 245 from the GARP Atlantic Tropical Experiment as example. The thermodynamic differences between non-precipitating convection and precipitating convection are discussed, as well

Deep Convection and the Solar Chromosphere
Solar Physics, 2012The manifestation of convection in deep layers of the Sun has been found in the dynamics of solar surface activity (Arkhypov, Antonov, and Khodachenko in Solar Phys.270, 1, 2011). Some chromospheric phenomena could be connected with deep convection, too. We justify this hypothesis with sunspot, Ca ii, Hα, and millimeter-wave radio data.
