1 In the climate system these forms of heat transfer are manifested in the motion of the atmosphere and ocean, on both local and global scales.  Radiation: The transfer of energy through electromagnetic waves. This form of energy transfer does not require the presence of matter to occur. In this form energy can travel through empty space from the Sun to the Earth and other planets in the solar system. Radiation also occurs within the climate system between the earth's surface and the atmosphere, and within the atmosphere and ocean.
The size of the sun determines its temperature and the amount of energy radiated. Electromagnetic energy from the sun comes to Earth in the form of radiation. The term radiation simply denotes the fact that the energy travels as rays, that is, in straight lines. In general, the terms solar energy and solar radiation simply refer to energy from the sun. Electromagnetic energy is produced when electric charges change their potential energy. It is characterized by the property that it is pure energy, not requiring any matter (or medium) for its existence or movement.
