convection

The mountains trap hot air and circulate the heat like a convection oven.

Bush, for example, recently listed a Montague Co. convection oven for $9,500 — far below its original price of roughly $21,000.

"Yes, more water vapor in the air can foster stronger convection, but a tornado is a very local feature and requires a very specific set of meteorological conditions, such as the right wind shear."

The analysis revealed that a type of convection similar to what is seen on Earth helps maintain Jupiter's storms, which can be thousands of miles wide and last for years.

This boiling region is called the "convection zone," where layers and plumes of plasma roil and flow.
