Hail is not unknown in Windhoek, but its occurrence usually denotes massive turbulence within the cloud, so much so that an exceptional build-up is required before the weight of precipitation is just too much for any convective current to prevent the downpour.
The breath from the monster's voice cools the molten rock, casts it into the convective current upwards into the mind, into consciousness, shaping what it is we think we see.
The swimming-up and sinking-down sets up a convective current, much as does cold air sinking toward the floor of a room.
Stamenkovic's team found that the pressure and viscosity inside a super-Earth would be so high that a stagnant, insulating layer would form outside the core, weakening the convective currents needed to drive plate tectonics thus making the process unlikely.

As hard as it might be to imagine, heat can be lost through a window by means of convective currents moving in the constricted spaces between the glazing layers.
Making it wider than the window will also stop convective currents that bring cool air into the room.
