  4. Etymology: From *, from θέρμη.


  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.

Webster Dictionary

  1. Thermaladjective

    of or pertaining to heat; warm; hot; as, the thermal unit; thermal waters


  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. Dmitry Zmeev:

    While it's unlikely that Lego blocks per se will be used as a part of a quantum computer, we've found the right direction for creating cheap thermal insulators : 3D printing, the Lego is made from ABS plastic and one can also create ABS structures simply by 3D printing them. We are currently studying the properties of such 3D printed structures at ultralow temperatures close to absolute zero.

  2. Ralph Lauren:

    The more we can think about our personal space and personal thermal dynamics, that’s the future that we’re all going to have to think about.

  3. Volodymyr Zelenskyy:

    The biggest nuclear power plant in Europe is on fire right now, russian tanks are shooting at the nuclear blocks. These are tanks equipped with thermal imagers, so they know what they are shooting at.

  4. Pete Schultz:

    This is the first time we have clear evidence of glasses on Earth that were created by the thermal radiation and winds from a fireball exploding just above the surface, to have such a dramatic effect on such a large area, this was a truly massive explosion. Lots of us have seen bolide( bright meteor) fireballs streaking across the sky, but those are tiny blips compared to this.

  5. Sean Solomon:

    The MESSENGER spacecraft has survived the severe thermal and radiation hazards of the inner solar system, including strong heating by Mercury's dayside surface and direct impact by coronal mass ejections and other energetic solar events, even though we know that the probe's days are numbered, MESSENGER has been a reliable source of exciting new information, and its loss will sadden all of us who have followed its successes.
