Summary

Weather is the condition of the atmosphere of a place at a particular time. Its elements are temperature, rainfall, humidity, wind, pressure, sunshine, cloud cover and evaporation. A weather station houses the instruments, with thermometers kept in a Stevenson screen so they record air temperature in the shade, not the sun's heat directly.
