This furnace utilizes induction
heating, which provides a steeper temperature
gradient, allowing faster crystal growth
rates to further minimize evaporation and reaction with the crucible.
The combined electron and ion
heating altered the
gradient, or spatial
rate of change in the plasma density.
When greenhouse gases increase, more longwave radiation is directed back at the ocean surface, which warms the cool - skin layer, lowers the thermal
gradient, and consequently reduces the
rate of
heat loss.
The thermal
gradient through this layer dictates the
rate of
heat loss from the (typically) warmer ocean surface, to the cooler atmosphere above.
Increased warming of the cool skin layer (via increased greenhouse gases) lowers its temperature
gradient (that is the temperature difference between the top and bottom of the layer), and this reduces the
rate at which
heat flows out of the ocean to the atmosphere.
The
rate of flow of
heat out of the ocean is determined by the temperature
gradient in the «cool skin layer», which resides within the thin viscous surface layer of ocean that is in contact with the atmosphere.
The
rate of flow of
heat out of the ocean is determined by the temperature
gradient in the «cool skin layer»
A smaller
gradient would slow down the
rate at which the oceanic
heat sink absorbed the forcing, but that effect would be pretty linear, nothing like the cyclic or step - function data that Trenbeth and others are trying to explain.
If you reduce the
rate of
heat flux from the the planet to space by increasing the density of greenhouse gases and thus altering the thermal
gradient, less
heat will flow from the
heat sink (ocean) to space.
The specific
heat of water vapour is higher than that of carbon dioxide, so it will reduce the
gradient slightly, and thus have a cooling effect, just as it does by reducing the
gradient to the «wet adiabatic lapse
rate» on Earth.
But take away that
heat engine and the implication is that there must be no lapse
rate or thermal
gradient in a column of gas.
The thermal
gradient (badly named a lapse
rate) allows
heat transfer downwards by diffusion into warmer regions when the thermodynamic equilibrium is disrupted with new energy absorbed higher up.
R GATES: The Longer - term
rate of ocean
heat storage is modulated by the total amount of greenhouse gases in the atmosphere which ultimately alter the net overall thermal
gradient between ocean
heat and space.
The Longer - term
rate of ocean
heat storage is modulated by the total amount of greenhouse gases in the atmosphere which ultimately alter the net overall thermal
gradient between ocean
heat and space.
That probably works as an alternate view of the pressure
gradient, but for lapse
rate it problematically implies that gravity drives
heat flow.
And yes, the thermal
gradient across the surface skin layer is what determines the
rate of
heat loss from ocean to atmosphere by conduction.
This reduces the
heat gradient and thus the
rate of loss of
heat from the ocean is also reduced.
Moreover, significant trends in sensible
heat and evaporation
rates are evident in satellite - derived datasets, especially in the Barents - Kara Sea region in the fall due to increases in the air - sea temperature and humidity
gradients, collocated with reductions in sea ice.
If weather events like hurricanes are a function of
heat gradients, not of
heat content, then it follows that raising Tmin more than Tmax, via atmospheric CO2, will cause their formation
rates and their magnitude to fall
