Summary

  • Weather means the temporary climatic conditions of the Earth's atmosphere: it consists of factors such as temperature, air pressure, wind, and precipitation.
  • Wind is air that flows from an area of high air pressure to an area of low air pressure.
  • Rain is formed as warm, humid air rises into higher altitudes. In high altitudes, the air cools down, and the moisture contained within it is condensed into droplets that eventually gather enough mass to fall back down to the surface of the Earth.
  • Convection rain is created when humid air is warmed up by the Sun.
  • Orographic rain is created when a coastal mountain range forces moist air flowing from the sea to rise.
  • Frontal rain is created when a cold air mass meets a warm air mass and the warm air rises above the cold air mass.
  • Tropical storms occur in the tropical zone.
  • Key words: weather, wind, rain, lightning, tropical storm, tornado.
