The team interpreted those shifts as the effect of cyclonic winds moving above and below the black hole at speeds of about 4000 kilometers per second, tens of thousands of times stronger than the most intense cyclones on Earth. (sciencemag.org)
But the icepack already shows effects of the gathering low - pressure system cyclonic circulation in today's Bremen map. (neven1.typepad.com)
However, at latitudes poleward of 40 ° in winter, positive correlations dominate as the water - holding capacity of the atmosphere limits precipitation amounts in cold conditions and warm air advection in cyclonic storms is accompanied by precipitation. (ipcc.ch)
