1. Thermal

   A thermal column (or thermal) is a rising mass of buoyant air, a convective current in the atmosphere, that transfers heat energy vertically. Thermals are created by the uneven heating of Earth's surface from solar radiation, and are an example of convection, specifically atmospheric convection.

1. thermal

   Thermal refers to heat or temperature. It is often used to describe processes that involve heat transfer, energy production, or temperature regulation. Thermal energy, specifically, is the energy that comes from heat, generated by the movement of tiny particles within an object or system. This motion of particles is an essential form of energy because it is responsible for changes in temperature, phase changes, and even for sustaining life.

1. Thermal

   A thermal column is a column of rising air in the lower altitudes of the Earth's atmosphere. Thermals are created by the uneven heating of the Earth's surface from solar radiation, and are an example of convection, specifically atmospheric convection. The Sun warms the ground, which in turn warms the air directly above it. Dark earth, urban areas and roadways are good sources of thermals. The warmer air near the surface expands, becoming less dense than the surrounding air mass. The mass of lighter air rises, and as it does, it cools due to it expands in the lower pressure of the higher altitude. It stops rising when it has cooled to the same temperature as the surrounding air. Associated with a thermal is a downward flow surrounding the thermal column. The downward moving exterior is caused by colder air being displaced at the top of the thermal. The size and strength of thermals are influenced by the properties of the lower atmosphere. Generally, when the air is cold, bubbles of warm air are formed by the ground heating the air above it and can rise like a hot air balloon. The air is then said to be unstable. If there is a warm layer of air higher up, an inversion can prevent thermals from rising high and the air is said to be stable.

Examples of THERMAL in a Sentence

1. Roberto Dondisch:

   Switching the fuel at thermal power plants from coal to natural gas will allow the country to greatly reduce greenhouse gas emissions.

2. Tatsuo Yasunaga:

   We will consider reducing thermal coal output or selling stakes in thermal coal mines.

3. Pete Cunningham:

   In addition to being the world's first smartphone to integrate thermal imaging it's also the world's most waterproof phone, you can take this to depths of five meters waterproof. It's also designed to be dropped from 1.8 meters onto concrete without smashing, so there's lots of other rugged credentials that means we deliver it in this size. I think over time you'll see the ability to reduce the thickness of the device as well.

4. Christine Cooper:

   Echidnas can’t pant, sweat or lick to lose heat, so they could be impacted by increasing temperature and our work shows alternative ways that echidnas can lose heat, explaining how they can be active under hotter conditions than previously thought, understanding the thermal biology of echidnas is also important to predict how they might respond to a warming climate.

5. Kristen Kish in a statement:

   We implemented daily temperature checks in our operations locations as an additional preventative measure to support the health and safety of our employees who continue to provide a critical service in our communities, we are now implementing the use of thermal cameras for temperature screening to create a more streamlined experience at some of our sites.
