Weather is an all-encompassing term used to describe all of the many and varied phenomena that can occur in the atmosphere of a planet. The term is normally taken to mean the activity of these phenomena over short periods of time, usually no more than a few days in length. Average atmospheric conditions over significantly longer periods are known as climate. Usage of the two terms often overlaps and the concepts are obviously very closely related.
Basic mechanism
Weather phenomena result from temperature differences around the globe, which arise mainly because areas closer to the tropics, around the equator, receive more energy from the Sun than more northern and southern regions, nearer to the Earth's poles.
