I'm not sure that there are ever atmopheric conditions on earth where this would happen – for example the pressure on Everest is approx 30Kpa (sea level its 101kPa) which is above the sublimation pressure shown on the phase diagram.
It does all the time. If you fill an ice tray and leave it in the freezer for months, the cubes will get smaller. Meat gets "freezer burnt" after a few months, because the H2O molecules leave the meat, drying it out. It didn't pass through the liquid phaseon the way.
And depth hoar in a snowpack is formed by recrystalisation of sublimated water vapour.
Edit: toys, Just realised that we're not quite taking about the same thing: The graph shows that at certain pressures and temperatures, changes in one will provoke a change in state of all the material from solid straight to gas, and I think I was talking about common or garden entropy, in the form of sublimation.
I think.
