The Weather Machine

In the atmosphere, phenomena and events are loosely divided into the realms of “weather” and “climate.” Climate is usually defined to be average weather and thus is thought of as the prevailing weather, which includes not just average conditions but also the range of variations and extremes. Climate inherently involves variations in which the atmosphere is influenced by and interacts with other parts of the climate system, and the external forcings. The large fluctuations in the atmosphere from hour to hour, or day to day, constitute the weather.
