The tidal locking on Gliese 581g greatly reduces its' interest level for Terran explorers. That would limit the liquid water (at best) to a twilight area around the planet's terminator.

Rather than an unusually dynamic atmosphere with perpetual winds sweeping from a too hot perpetual dayside to a too cold eternal nightside, I suspect you would actually see some sort of static Venusian atmosphere.

Some future astronomical project might be able to confirm this by getting a too strong Co2 spectrum from the the planet.

So just personally I would not rush to write this place up as the target for Man's first extra-solar colonization effort or similar rpg scenario.

To the best of my understanding the habitable zone of any M-class dwarf is going to be filled with tidally locked worlds. You'd need some sort of exotic scenario such as a double planet system tidally locked to each other but still spinning relative to the star or something like that.
