Webster: "Having to do with heat". As we have had thermal underwear for cold weather activities for years, there are now thermal water wear garments to facilitate heat retention for water activities.
Caused by heat. A heat event or warm air, etc.
Of, using, producing, or caused by heat.
a knit or woven fabric constructed so as to trap warm air between the yarns. Often in a waffle or honeycomb texture. Used for blankets. underwear.
is a long-wearing 100% cotton knit featuring heat-retaining air pockets.
rising current of warm air
caused by or designed to retain heat; "a thermal burn"; "thermal underwear"
a column of rising air, caused by uneven heating of the earth
a column of rising air in the lower altitudes of the Earth's atmosphere
a column of rising warm air surrounded by descending cold air
a column of warm air that rises from the ground or water on a sunny day
a column of warm air that's rising
a column of warm rising air that occurs when one section of the ground warms faster then other sections
a mass of rising hot air produced by the intense heating which occurs on the south side of a mountain slope due to its position in relation to the autumn sun
an ascending current of heated air, usually found where the heat from a plain is pushed by prevailing winds against a mountain range
a rising bubble of warm air
a rising column of air that I take advantage of to gain altitude - often thousands of feet up - to extend a flight and travel cross-country
a rising column of air, which has been warmed by contact with the ground that has been heated by the sun
a rising parcel of warm air
Thermal means "having to do with heat."
A finger image capture technique that uses a sensor to sense heat from the finger and thus capture a finger image pattern.
Refers to the use of heat in any process.
Pertaining to heat gain and heat retention.
A rising column of relatively warm air.
rising column or bubble of warm air.
A relatively small-scale, rising air current produced when the earth's surface is heated. Thermals are a common source of low level turbulence for aircraft.
Thermals are columns of rising warm air that both model and full size sailplanes take advantage of when trying to stay aloft. There are all kinds of thermals, some are small 'puffs', while others are monstrous. I've been in thermals that were strong and difficult to 'get out of'. The art of spotting and utilizing the rising air in a thermal one of the most interesting things to master.
Rising body of hot air that can take a sailplane to a great height.
A rising column of warm air, often found above rock outcrops, buildings or parking lots.
A printing system where dots are selectively heated and cooled and dragged upon heat-sensitive paper. The paper turns dark in the heated areas.
Small rising column of air due to surface heating.
A term used to identify a type of electric generating station, capacity, capability, or output in which the source of energy for the prime mover is heat.
windows Windows designed with multiple panes to trap air and provide greater insulation.
A printing system where dots are selectively heated, cooled and impressed on a heat sensitive paper. The paper changes colour in the heated areas.
Adjective describing the effects of temperature or heat, e.g. thermal effects.
A volume of air which rises because it is warmer (less dense) than its environment. Many thermals form when the air near the surface is warmed by contact with ground heated by the sun.
a warm current of air rising from the sun-warmed earth that can be used to gain altitude while in flight. a common source of low level turbulence.
1. Pertaining to temperature or heat. 2. A discrete buoyant element in which the buoyancy is confined to a limited volume of fluid. See plume. 3. A relatively small-scale, rising current of air produced when the atmosphere is heated enough locally by the earth's surface to produce absolute instability in its lowest layers. The use of this term is usually reserved to denote those currents either too small and/or too dry to produce convective clouds; thus, thermals are a common source of low-level clear-air turbulence. It is generally believed that the term originated in glider flying, and it is still very commonly used in this reference.
