Thunderstorm near Garajau,  Madeira Weather  is the state of the  atmosphere , to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1]  Most weather phenomena occur in the lowest level of the atmosphere, the  troposphere , [2] [3]  just below the  stratosphere . Weather refers to day-to-day temperature and  precipitation  activity, whereas  climate  is the term for the averaging of atmospheric conditions over longer periods of time. [4]  When used without qualification, "weather" is generally understood to mean the weather of  Earth . Weather is driven by air pressure, temperature and moisture differences between one place and another. These differences can occur due to the sun's angle at any particular spot, which varies with  latitude .

Lightning

Lightning flashes during a  thunderstorm Play media High-speed, slow-motion lightning video captured at 6,200 frames per second. Lightning  is a sudden  electrostatic discharge  that occurs during a  thunderstorm . This discharge occurs between  electrically charged  regions of a  cloud  (called intra-cloud lightning or IC), between two clouds (CC lightning), or between a cloud and the ground (CG lightning). The charged regions in the atmosphere temporarily equalize themselves through this discharge referred to as a  strike  if it hits an object on the ground, and a  flash , if it occurs within a cloud. Lightning causes light in the form of  plasma , and sound in the form of  thunder . Lightning may be seen and not heard when it occurs at a distance too great for the sound to carry as far as the light from the strike or flash.
