35th anniversary of the publication first documenting the eyewall cycle in intense tropical cyclones

In February, 1982, The Journal of the Atmospheric Sciences published a ground-breaking study by Hugh Willoughby, Jean Clos, and Mohammed Shoreibah on what became to be known as the eyewall replacement cycle.  Using data obtained from NOAA P3 flights into very intense Hurricanes Anita, David and Allen, they found that a common feature of intense […]
