Excesive over heating for an indefinate period of time may cause a hurrican to circulate in the ocean for months or even years. Since this is a planet of mostly water, rising sea levels and vast areas of oceans may provide the idea situation for a Jupiter like storm system to occure on this planet.

Interesting idea.
Unlikely. Hurricanes and typhoons are formed from the rising air over warm oceans. When the Hurricanes reach land, the storms begin to dissipate. Even with significant global warming, hurricanes and typhoons will still dissipate when crossing the relatively cool surface of land at night. Therefore, unless there is a wind pattern that keeps the storm over warm water permanently then the storms will be transient events. Anyway, global warming might cause changes to storm patterns and their intensity. But the earth's surface will keep the atmosphere in a dynamic state which gives rise to storms and likewise breaks them down. |

Besides sea-surface temperatures, hurricanes are also strongly affected by vertical wind shear (increase in winds w/ height).
I am not sure of what would happen w/ the vertical wind shear in an excessively warmed scenario, but usually when convection around the ITCZ is enhanced, a stronger Hadley-Walker circulation is developed and generates a strong sub-tropical high. A stronger subtropical high would generally bring on stronger trade winds and probably stronger winds aloft too. If this were to happen, hurricane potential could actually go down because they need very weak environmental winds to start up and intensify. |
