Yes... -ish. Hurricanes are, in effect, a big heat engine that helps to distribute heat towards the poles from the equator. It is one of Nature's more efficient heat transfer mechanisms, among natural systems.
Hurricanes both draw heat from the ocean surface and the atmospheric boundary layer, and eject it into the upper air through convection and the latent heat released through condensation at the expense of warming the upper-mid layers of the atmosphere.. The surface level winds mix the sea surface waters into deeper layers, cooling the surface at the expense of warming the uppermost marine layers.
You don't, however, get anything for free. On a global scale the heat doesn't so much dissipate as it does just redistribute. The heat is all still there, it's just less concentrated in the equatorial surface-level atmospheric and marine layers by being distributed into upper atmospheric layers, deeper marine layers, and higher latitudes. The average temperature integrated across the entire volume of affected regions might be net lower, but not by enough to matter, and the system is still overall warmer than its long term average.
Technology Connection enter the chat. "Did someone say giant heatpump"?
If we just install giant heat pipes from the equator to the polls. :thinking:
They're already installed. We call them ocean currents, and climate change is about to wreck them.
Sure sure, but what if we didn't care about how nature did it and did it ourselves. I can't see a way this could go wrong.
New video just dropped by the way!
Look up Atmospheric Vortex Engines. Think giant fire tornados driving turbines. The more realistic designs use waste heat but Popular Science or Mechanics had a story decades ago where someone proposed creating giant fire tornados in the desert.
I just want to say how much I appreciate this reply. No idea how factual it is but I really dig the detailed and thoughtful response, thanks for sharing!
Thank you for the detailed answer.
