Radar is a great tool for meteorologists during any weather event, but especially during severe weather. The MRMS toolkit is one that helps radar meteorologists during severe weather figure out what is happening in the storm by using multiple radar site and computer model data.
Officially speaking, MRMS is…
The Multi-Radar Multi-Sensor (MRMS) project utilizes an automated system that rapidly and intelligently integrates data from multiple radars and radar networks, surface observations, numerical weather prediction (NWP) models, and climatology to generate seamless, high spatio-temporal resolution mosaics.
The Multiple Radar Multiple Sensor (MRMS) system combines data streams from multiple radars, satellites, surface observations, upper air observations, lightning reports, rain gauges and numerical weather prediction models to produce a suite of decision-support products every two minutes. Because it provides better depictions of high-impact weather events such as heavy rain, snow, hail, tornadoes, and other threats, forecasters can quickly diagnose severe weather and issue more accurate and earlier forecasts and warnings.
In other words, like I said, the MRMS toolkit is one that helps radar meteorologists. The video above walks you through how meteorologists use this tool as well as how it has helped identify severe weather when single radar data may have come up a bit short.
