Dual-polarization weather radar

❝ For decades, radar has been used by the National Weather Service to gather a wealth of meteorological data to track thunderstorms, hurricanes, blizzards and everything in between…

But an advancement in radar has unveiled even more information than ever before. Enter: Dual-polarization weather radar…This new technology provides 14 new radar products that will support our mission to serve our partners and customers,” the NWS explained.

❝ All of these radar products can be found on sophisticated weather radar apps for smartphones and computers, such as RadarScope and GR2Analyst.

I am going to be trying these asap! Most science junkies are weather junkies. 🙂

    “Spotted: A Swarm Of Ladybugs So Huge, It Showed Up On National Weather Service Radar” (NPR June 6, 2019) https://www.npr.org/2019/06/06/730254007/spotted-a-swarm-of-ladybugs-so-huge-it-showed-up-on-national-weather-service-rad On the radar, the cloud of insects looked like a “light rainstorm” — not quite the density of a severe thunderstorm. According to reports they were flying about a mile above the ground in the cloud that was about 10 miles wide.

    “The long-awaited upgrade to the US weather forecast model is here” https://arstechnica.com/science/2019/06/us-weather-forecasts-get-a-software-update/ “For the first time in about 40 years, the guts of the US model got swapped out for something new today. The upgrade brings us a new “Finite-Volume Cubed-Sphere” (or FV3) dynamical core [see https://www.gfdl.noaa.gov/fv3/ ], which simulates the basic atmospheric physics at the heart of this endeavor, a change that has been in the works for a while.
    The new core had its origins in simulating atmospheric chemistry but ended up being adapted into other models. A few years ago, it was selected to replace the old core in the US Global Forecast System model. And for more than a year now, the new version of the model has been running in parallel so its results could be compared to the operational model.
    …Improvements to the forecast system can come from other fronts, too, from recent upgrades to NOAA’s supercomputers that drive the models [ https://www.noaa.gov/media-release/noaa-kicks-off-2018-with-massive-supercomputer-upgrade ] to launches of the latest and greatest satellites*. But switching out the core of the main forecast model is a big deal that will hopefully help it keep up with the progress being made by others. Right now, the European Centre for Medium-Range Weather Forecasts model is generally seen as the top dog.”
