Heat Wave

Heat wave

A heat wave or heatwave, sometimes described as extreme heat, is a period of abnormally hot weather that lasts for multiple days. A heat wave is usually measured relative to the usual climate in the area and to normal temperatures for the season. The main difficulties with this broad definition emerge when one must quantify what the 'normal' temperature state is, and what the spatial extent of the event may or must be. Temperatures that humans from a hotter climate consider normal can be regarded as a heat wave in a cooler area. This would be the case if the warm temperatures are outside the normal climate pattern for that area.

Heat Wave (1963 song)

"Heat Wave" is a 1963 song written by Holland–Dozier–Holland. It was first made popular by the Motown vocal group Martha and the Vandellas, who issued it as a single on July 10, 1963, on the Motown subsidiary Gordy Records. The single reached number one on the Billboard Hot R&B chart and number 4 on the Billboard Hot 100.

Heat

In thermodynamics, heat is defined as energy in transfer between a body and its surroundings, other than through thermodynamic work or through transfer of matter.

Wave

In mathematics and physical science, a wave is a propagating dynamic disturbance of one or more quantities. Periodic waves oscillate repeatedly about an equilibrium (resting) value at some frequency. When the entire waveform moves in one direction, it is said to be a traveling wave; by contrast, a pair of identical superimposed periodic waves traveling in opposite directions makes a standing wave. In a standing wave, the amplitude of vibration has nulls at some positions where the wave amplitude appears smaller or even zero.
