1.) A supercell is the only type of thunderstorm that rotates. That rotation inside the storm is called a mesocyclone—and it can last for hours. 2.) Not all supercells produce tornadoes. But almost all strong tornadoes come from supercells. 3.) These storms are known for their structure. From stacked plates to striated bands, the shape tells forecasters a lot about what’s going on inside. 4.) Wind shear is what helps a storm organize. It’s the change in wind speed and direction with height—and it’s crucial for creating the rotation that separates supercells from ordinary thunderstorms. 5.) Supercells can form from storms that look weak at first. In this photo, what started as a messy group of storms evolved quickly thanks to strong upper-level wind shear. 6.) Outflow-dominant supercells push more cool air forward than they pull in warm air. This often makes them look stunning—but also limits tornado potential. 📸 Photo: “Liberal Approach” by Roger Edwards via SkyPix #supercell #stormchasing #weatherfacts #virałpost #windshear #stormstructure #BeginnerWeather
