Ocean Convective Available Potential Energy. Part I: Concept and Calculation
Thermobaric convection (type II convection) and thermobaric cabbeling (type III convection) might substantially contribute to vertical mixing, vertical heat transport, and deep-water formation in the World Ocean.However, the extent of this contribution remains poorly constrained. The concept of ocean convective available potential energy (OCAPE), the thermobaric energy source for type II and ty...
متن کاملComparison of Thermal Comfort by Radiant Heating and Convective Heating
Currently, convective heating with a heat-pump system, which has high energy efficiency, is popular for room heating. However, it is possible that energy savings using convective heating can be further improved using heat pumps that service both occupied and unoccupied spaces. Moreover, convective heating increases vertical temperature gradients in a room; thus, it is hard to say whether occupa...
متن کاملWhy does tropical convective available potential energy (CAPE) increase with warming?
Recent work has produced a theory for tropical convective available potential energy (CAPE) that highlights the Clausius-Clapeyron (CC) scaling of the atmosphere’s saturation deficit as a driver of increases in CAPE with warming. Here we test this so-called “zero-buoyancy” theory for CAPE by modulating the saturation deficit of cloud-resolving simulations of radiative-convective equilibrium in ...
متن کاملPrimary instabilities in convective cells due to nonuniform heating
We study a convection problem in a container with a surface open to the air and heated by a long wire placed at the bottom. Coupled buoyancy and thermocapillarity effects are taken into account. A basic convective state appears as soon as a temperature gradient with horizontal component different from zero is applied. It consists of two big rolls that fill the convective cell and are parallel t...
متن کاملElectron Heating by the Cross-shock Electric Potential Electron Heating by the Cross-shock Electric Potential
Electrons can experience super-adiabatic heating at a collisionless shock due to the presence of a cross-shock electric potential. This heating can greatly exceed the temperature rise associated with the conservation of the magnetic moment of the electrons as they move into the stronger magnetic eld downstream of the shock. The criterion for the onset of super-adiabatic heating and the eeects o...
