Radiation
From Glossary of Meteorology
radiation
- The process by which electromagnetic radiation is propagated through free space.
The propagation takes place at the speed of light (3.00 x 108 m s-1 in vacuum) by way of joint (orthogonal) oscillations in the electric and magnetic fields. This process is to be distinguished from other forms of energy transfer such as conduction and convection.
- Propagation of energy by any physical quantity governed by a wave equation.
