Can We Quantify the Energy Released by Hurricanes?

Click For Summary

Discussion Overview

The discussion revolves around the quantification of energy released by hurricanes, exploring the sources of this energy and the mechanisms involved in its transformation. Participants examine theoretical and conceptual aspects of hurricane energy dynamics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions whether there is a way to quantify the energy released by a hurricane and inquires about its energy source.
  • Another participant draws parallels between the energy sources of tornadoes and hurricanes, suggesting that spatial inhomogeneity, particularly pressure cells, plays a role in powering hurricanes.
  • A different participant proposes that thermal energy from ocean water is converted into kinetic energy in hurricanes, speculating about a runaway breakdown effect in strong storms.
  • One participant emphasizes the role of water vapor in hurricanes, noting that heat is released when this vapor condenses at high altitudes, linking the hurricane's power to the evaporation rate of water.
  • There is a mention of strong hurricanes transforming the water surface into numerous small bubbles, which increases the effective water surface area and thus the evaporation rate.

Areas of Agreement / Disagreement

Participants express various hypotheses regarding the energy dynamics of hurricanes, but no consensus is reached on a definitive method for quantifying the energy released or the primary energy sources involved.

Contextual Notes

Participants acknowledge the complexity of the mechanisms involved, including the dependence on factors like evaporation rates and the behavior of water surfaces under strong winds, but do not resolve these complexities.

Is there a way the quantify the energy 'released' by a hurricane? Does the energy have a source so to speak?
 
Physics news on Phys.org
The energy source of a tornado is the same as for a solar vortex plant or (a bit less unconventionally) a solar updraft tower: during the day the air at the ground becomes less dense than the air high in the atmosphere.

For a hurricane I suppose much of the wind (following the Coriolis effect) must be powered by some spatial inhomogeneity, the pressure cell.
 
My best guess is that thermal energy from the water is being converted into kinetic energy. With class five storms, it appears that there is some kind of run away breakdown effect...some sort of resonance or something.

I'd like to know how many joules of energy are actually release in a hurricane.
 
It's the water vapor above the sea water that is sucked up by the hurricane that releases heat when it condenses high in the sky. So, the power of the hurricane is related to the evaporation rate of the water.

I've read that strong hurricanes transform the water surface into a big volume of small water bubbles. As the winds become stronger and stronger, you get more and more waves that start to break. Above a certain wind speed, there us no clearly definable water surface anymore.

The total evaporation rate is proportional the the water surface. In case of strong hurricanes, the water surface is the sum of the surfaces of all the water bubbles which is huge...
