If this were a weather map aloft, then winds would be blowing counterclockwise around the low and parallel to the isobars. Briefly account for the darker green colors surrounding the white circle near at the center of Floyd. The infrared signature indicates very cold cloud tops totally encircling a clear center. The clear center is the eye of the storm and the darker green colors are indicating the tops of the cumulonimbus surrounding the eye wall. We mentioned in class that the usual variation of wind speed with height in storms is reversed with hurricanes.
Wind speeds are stronger near the ground than aloft.
This also shows up as the close spacing of isobars on the surface map and the contours being further apart on the 300 mb chart. Figure 3 is the 2015 UTC 04 October radar summary.
