To illustrate the diversity of tropical cyclone spatial scales, it is interesting to compare the large eye of Hurricane Norbert (in the eastern Pacific Ocean)<\/em> with the small cluster of deep convection around the core of Tropical Storm Marco (2 days earlier in the Gulf of Mexico)<\/em> — Marco is not much larger than the eye of Norbert! The visible and IR images shown below are from the same satellite (GOES-13)<\/em> at the same time of day (20:00 UTC),<\/em> displayed with the same magnification (zoomed in to an effective 0.5 km resolution)<\/em>. According to the National Hurricane Center discussions<\/strong><\/a>, Tropical Storm Marco may have been one of the smallest tropical cyclones on record, with tropical storm force winds only extending about 10 nautical miles away from the center.<\/p>\n
