A jet stream is best described as hurricane-force winds that circle the earth.

Here's a step-by-step explanation:

1. Jet streams are fast flowing, narrow air currents found in the atmosphere.
2. They are located near the altitude of the tropopause, the boundary between the troposphere (where weather phenomena occur) and the stratosphere.
3. These streams are typically thousands of kilometers long, a few hundred kilometers wide, and only a few kilometers thick.
4. They are caused by a combination of the planet's rotation on its axis and atmospheric heating (by solar radiation).
5. Jet streams are strongest in the winter when the temperature gradient is steeper between the equatorial region and the poles.
6. They can reach speeds of over 200 km/h (124 mph), hence the term "hurricane-force winds".
7. They do not distribute energy in the form of massive vertical convection cells, nor do they include the Hadley, Ferrel, and Polar convection cells. These are different atmospheric phenomena.

So, the best answer is "Hurricane-force winds that circle the earth".
