Convection [noun]

The physics of the design itself has been around for much longer than that—they’re essentially a refined design of the traditional convection oven.

Water vapor and air constantly circulate in turbulent convection currents.

The star’s temperature hadn’t dropped as much as would be expected if the dimming was from something intrinsic to the star, like its convection cycles, the pair reported in the March 10 Astrophysical Journal Letters.

That convection cycle puts Betelgeuse on a semiregular dimmer switch that fluctuates roughly every 400 days or so.

The convection technology in air fryers allows you to roast, bake, and even dehydrate your favorite foods.

It’s convection-powered, but with the option to switch out of convection mode for tasks like broiling or toasting.

The bag may be called a "convection shield," slowing convection-cooling due to air currents.

This mode of propagation may better be described as a convection of excitation.

This is illustrated by the seasonal variation in convection.

In summer, when the gradient is steepest, convection reaches its maximum.
