Consequences of strong wind on an alien Planet on the possibility of life I was surprised to learn recently that Neptune has winds of 1500 miles an hour. 

My question is whether life could ever evolve on such a Planet that has such powerful winds? Not necessarily on Neptune of course but on another exoplanet in another Solar System.
We know that life can start and evolve quite well on a planet with 250 mph winds: You're living on one. The jet stream can reach this speed in the Earth's atmosphere.

Beyond that it is speculation. While not much is going to survive on the surface if there are surface winds of 1500mph at a static pressure of anything like 1atm, I can see no problem of life developing in the depth of the ocean no matter what the wind speed is.  

However I futher suggest that 1500mph winds cannot happen at the surface of a terrestrial planet that is anything like the Earth. The extreme conditions needed to create a surface wind of 1500mph on a daily basis may prevent any kind of life as we know it. But then the winds are not the acutal problem but the conditions needed to produce them.
