The heaviest rainfall is shown in red, green, yellow with blue

being the lightest.

•These images come from geostationary satellites. •They record visible light from the sun reflected back to the satellite by cloud tops and land and sea surfaces. •They are equivalent to a black and white photograph from space. •However, visible pictures can only be made during daylight hours.

•The infrared image shows the invisible infrared radiation emitted directly by cloud tops and land or ocean surfaces. •The warmer an object is, the more intensely it emits radiation, thus allowing us to determine its temperature. •Cooler temperatures show as lighter tones and warmer as darker.•Lighter areas of cloud show where the cloud tops are cooler and therefore where weather features like fronts and shower clouds are. •The advantage of infrared images is that they can be recorded 24 hours a day.
