Explanation of how a radar operates and its importance to meteorologists.
Radar is a vital tool for weather forecasting. Environment and Climate Change Canada currently operates over 30 radars from coast to coast. As part of the ongoing radar renewal projects, many of these radars will be upgraded and new radars installed. These upgrades will allow meteorologists to produce more accurate weather warnings and forecasts.
Each radar sends out pulses of “electromagnetic energy”, which encounters precipitation targets such as rain droplets, snowflakes and hail. The returned energy from the radar is then processed and turned into a variety of weather products such as the standard color radar image, which depicts precipitation intensity. Doppler radar imagery allows meteorologists to more accurately forecast summer tornadoes, winter freezing rain and wind shear for aviation safety during take-off and landing.
Radars are key in supporting Environment and Climate Change Canada’s mandate to inform Canadians, keeping them safe and able to plan and adapt to our diverse spectrum of weather as well as minimizing the potential for property damage.
