how fast are the winds in the great red spot on jupiter
Great Red Spot Careful tracking of atmospheric features revealed the spot's counter-clockwise circulation as far back as 1966, observations dramatically confirmed by the first time-lapse movies from the Voyager fly-bys.[23] The spot is confined by a modest eastward jet stream to its south and a very strong westward one to its north.[24] Though winds around the edge of the spot peak at ~120 metres per second (432 kilometres per hour), currents inside it seem stagnant, with little inflow or outflow.[25] The rotation period of the spot has decreased with time, perhaps as a direct result of its steady reduction in size.[26]
