“This resulted in a great deal of wind shear and vorticity, which is the tendency for the atmosphere to spin.”
“Burg said the snow showers are rotating around what meteorologists call a vorticity maximum.”
“Last night's GFS (6z) model forecasts of surface pressures and 850 temperatures (top panels) and 500 mb heights and vorticity (spin at around 18000 ft, bottom panels).”
“Upper level disturbance or "vorticity maximum" at 500 mb about 18,000 feet at 1 a.m.”
“The 84 hour surface and 500 mb (18,000 ft) height and vorticity (atmospheric spin) for the NAM (top panels) and GFS (bottom panels) are shown below.”
“Left: 500 mb (18,000 feet) heights and vorticity (atmospheric spin) on the left.”
“The colors represent the vorticity or "amount of rotation" that this particle experiences, where red signifies positive (east-west) flow and blue signifies negative (west-east) flow.”
“Global ozone trends in potential vorticity coordinates using TOMS and GOME intercompared against the Dobson network.”
“It was claimed that if one observed when the ink stopped swirling, meaning the viscosity of the water had dissipated its initial vorticity or curl; i.e.\nabla \times U = 0 then, if the plug was extracted ever so slowly so as not to introduce any additional vorticity, the tub would empty with a counterclockwise swirl in the northern hemisphere.”
“We get one cell that just pops and turns because (INAUDIBLE) way up here so we have a lot of spin or a lot of vorticity with it.”

I'm always entertained by the terms @immerito tweets using the hashtag #termsfromtoday. As best I can tell, the tag emerged in mid 2011 after a brief flirtation with an alternate hashtag form. You'...
