RADAR (RAdio Detection And Ranging)
It was during World War II that aircraft radar operators noticed something causing interferences on their displays, and those disturbances were masking potential targets. Further on they discovered that that clutter was caused by weather. This marked the beginning of a new era for weather prediction. Scientists began to study the phenomenon and soon after the war, surplus radars were used to detect precipitation!
