Do you know what vorticity is? Ocean Surface Vorticity is the subject of a new SOS dataset! It can be thought of as the rate of fluid rotation. Read more about it here: http://sos.noaa.gov/Datasets/dataset.php?id=604 | NOAA Science On a Sphere

🌪️ Boundaries: Tornado magnets with extreme potential This EF-4 tornado, producing violent damage just west of I-35, formed from a supercell that developed at a boundary intersection before riding that boundary eastward. Boundaries are often tornado magnets, as storms tracking along them tend to show an enhanced ability to produce tornadoes. The exact mechanisms behind this are still being studied, but increased wind shear and low-level vorticity (spin) along these boundaries are widely believe
