1) contributes to j, but also the convective current of charges of opposite sign, moving along with the medium and immovable in its rest frame (i.e., the positive ions for the moving circuit of Fig.
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.
He noted that heavy rain and strong winds caused by the formation of cumulonimbus clouds, the primary source of lightning storm formation, were due to the strong convective currents in the cloud.
We see convective currents in a pot of boiling water, with hot bubbles rising to the top and cooler water sinking to the bottom.
The purpose of this paper is to numerically simulate the processes of highly developed convection of a fuel liquid at high Rayleigh numbers and to study the application of approaches to the description of turbulence for freely convective currents. The results of modeling based on RANS, RSM, and LES approaches are presented.
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.
