Understanding Radar Technology: Its Evolution and Applications in Weather Detection

This article explores the history and functionality of radar technology, originally developed during WWII for detecting enemy aircraft. As an active remote sensing tool, radar transmits and receives electromagnetic radiation pulses, enabling real-time detection of various atmospheric phenomena. The discussion includes detailed examples of CAPPI maps showing radar data at 3 km and 7 km heights near Montréal, Canada, on August 3, 1988, and its applications in weather forecasting using different modes such as Clear-Air and Precipitation Mode.
