Weather refers to various phenomenon that occur in the
atmosphere of a
planet. On
Earth the regular events include
wind, storm
?s, rain
? and
snow, which occur particularly in the troposphere
?, the lower part of the atmosphere. Weather is driven by energy from the
sun, with key factors such as
temperature, humidity
?, [atmospheric pressure]
?, [cloud cover]
?, [wind speed]
?, and elevation
?.
Weather stations all around the world measure these conditions on a continuous basis. The weather system is an inherently chaotic system; practically this means that meterologists can only predict the weather a few days in the future.
