A good example is the Doppler Radar which originated from the works of an Austrian physicist Christian Doppler in the 1840’s. (Related links: http://en.wikipedia.org/wiki/Doppler_radar) The Doppler radar sends out radio waves in the air from an antenna and as radio waves travel in the atmosphere and hit objects in the air such as clouds, raindrops, dusts and even insects, the waves are scattered and reflected to all direction, some of them bounced back and collected by the Doppler radar itself. The frequency of the recovered waves are then translated by computers into information and images that measure the speed, direction, density as well as location of atmospheric objects such as wind and precipitation.
In short the Doppler radar could have determined the amount of rainfall that Ondoy will bring. Those information could have warned the authorities and public of the intensity of the possible rainfall to come, the exact location and time of its arrival. That could have changed the story of Ondoy. Unfortunately and ironically, the poor Filipinos despite being situated in the typhoon belt doesn’t even have a single Doppler radar.
