A colossal and unusually symmetric cloud ring was captured by NASA’s Terra satellite hovering alone in the central Pacific Ocean, revealing a rare atmospheric event that continues to intrigue ...

The fluffy ring is made up of cumulus clouds that have been sculpted into a Rayleigh-Benard convection cell — a meteorological phenomenon powered by the rising and falling of air that's been ...

The widths of the lines show occasional as well as longer term changes of a few percent but no evidence for giant convection cells. These spectroscopic observations are more consistent with a ...

(High pressures within the Earth cause material to freeze at high temperatures.) This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic ...

Often times, thunderstorms pop up to to warm air. Meteorologist Sara Blue explains how this happens. TYLER, Texas — Thunderstorms form from a process called convection, or the transfer of heat. Hot ...
