rising warm air

Rising warm air leaves low pressure above the surface.

Chilled panels cool the rising warm air, which then drops, creating a natural convection current.

The birds fly the way gliders do - by catching pockets of rising warm air, or thermals.

In good sunlight, the land gets warm and generates large columns of rising warm air in some places.

Natural convection causing rising warm air and falling cooler air can result in an uneven stratification of heat.

Wind would cease to exist because there would be no lateral movement of cool air to replace rising warm air at the ground's surface.

They are formed by rising warm air that has been heated by the ground, which in turn has been heated by the sun.

The rising warm air reduces the pressure in the base of the building, drawing cold air in through either open doors, windows, or other openings and leakage.

Tornadoes require supercell-like conditions, where the storm cloud tilts like the Tower of Pisa, allowing cooler downdrafts to sink without interfering with rising warm air.

Ferrel demonstrated that it is the tendency of rising warm air, as it rotates due to the Coriolis effect, to pull in air from more southerly, warmer regions and transport it poleward.

During the winter it is the relatively high elevation of the Short Hills Bench which allows it to benefit from rising warm air currents blowing south off Lake Ontario, in much the same way as the lower lying coastal sub-appellations do.

Nimbostratus will occur along a warm front where the slowly rising warm air mass creates nimbostratus along with shallower stratus clouds producing less rain, these clouds being preceded by higher-level clouds such as cirrostratus and altostratus clouds.

As it spiraled inward, it picked up heat from the sea, sped up, packed in more closely around the central column; it became harder and harder for more warm air to push its way into the center and up the column, now kilometers thick, of rising warm air.
