The temperature perceived by people as a result of high atmospheric humidity coupled with high air temperatures.
Temperature
The average kinetic movement of atoms and molecules of a substance
Heat
The internal energy transferred between materials or systems due to their temperature differences.
Conduction
The process by which energy Is transferred through a substance or between objects in direct contact.
Convection
The transfer of heat through movement of mass within a fluid (liquid or gas)
Radiation
The process by which wave energy travels through the vacuum of space or through a physical medium such as air or water.
Continental effect
The increase in seasonality with distance from the oceans
Specific Heat
The heat required to raise the temperature of any object or material by a given amount
Radiant energy (or Radiation)
Energy propagated in the form of electromagnetic waves, including visible light and heat.
Electromagnetic spectrum (EMS)
The full range of wavelengths of radiant energy.
Longwave Radiation (LWR)
