Just how strong are the winds in a tornado? 🌪️
A newly published paper by NSSL researchers concludes that radar-based estimates of near-ground wind speeds in tornadoes are frequently higher than estimates derived from damage using the EF scale.

🌀🌪️ Supercells are long-lived, highly-organized storms containing an updraft that is tilted/rotating. Most significant tornadoes and hailstones larger than a golf ball produced in the U.S. come from supercells.

A squall line 🌩️🌩️🌩️ is a group of storms arranged in a line, often accompanied by “squalls” of high wind and heavy rain. They move quickly & can be 100s of miles long but are typically only ~10-20 miles wide.

PERiLS studied tornadoes in squalls
SCIENCE IMPACT: The experimental Warn-on-Forecast System yielded more than an hour of lead time on the recent Greenfield, Iowa tornado.

Don’t flip your lid! ATD gets a new radome
A "radome" is a weatherproof enclosure that protects a radar antenna. The Advanced Technology Demonstrator (ATD) is the first full-scale, S-band, dual-polarization phased array weather radar.
