thermal column

The warm less dense air rises in what's called a thermal column.

And it's these thermal columns that support the Paraglider carrying it up into the sky.

Associated with a thermal is a downward flow surrounding the thermal column.

Some large broad-winged birds rely on thermal columns of rising hot air to enable them to soar.

The player's movement is affected by wind currents and altitude can be gained by flying through thermal columns.

A thermal column (or thermal) is a vertical section of rising air in the lower altitudes of the Earth's atmosphere.

In a similar fashion to migratory birds using thermal columns, saltwater crocodiles use ocean currents to travel long distances.

The Sun's thermal columns are Bénard cells and take the shape of hexagonal prisms.

As a result, thermal convection occurs as thermal columns carry hot material to the surface (photosphere) of the Sun.

The thermal columns in the convection zone form an imprint on the surface of the Sun as the solar granulation and supergranulation.

In 1945, he was awarded a PhD in Mechanical engineering with emphasizing on thermal column and its applicant physics.

Granules on the photosphere of the Sun are caused by convection currents (thermal columns, Bénard cells) of plasma within the Sun's convective zone.

Thermal Column: Inoperative (The reactor was built with a thermal column, to be a large source of thermal neutrons.

Especially large wildfires may affect air currents in their immediate vicinities by the stack effect: air rises as it is heated, and large wildfires create powerful updrafts that will draw in new, cooler air from surrounding areas in thermal columns.
