Associated with a thermal is a downward flow surrounding the thermal column.
2.
A thermal column ( or thermal ) is a vertical section of rising air in the lower altitudes of the Earth's atmosphere.
3.
"' Granules "'on the photosphere of the Sun are caused by convection currents ( thermal columns, B�nard cells ) of plasma within the Sun's convective zone.
4.
A thermal column, consisting of a block of graphite, provides a source of rabbits, are used to pneumatically inject a sample directly into the core of the reactor for a specified amount of time.
5.
For most land-birds, such barriers could consist in seas, large water bodies or high mountain ranges, because of the lack of stopover or feeding sites, or the lack of thermal columns for broad-winged birds.
6.
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.
7.
A "'thermal column "'( or "'thermal "') is a column of rising air in the lower altitudes of updraft . Thermals are created by the uneven heating of Earth's surface from solar radiation, and are an example of convection, specifically atmospheric convection.
