TCOTD – Typhoon Joan- Oct. 16
October 16
1997 JOAN 125 knots in the Western North Pacific
This system was one of the most intense cyclone during the satellite era. This image is a few days before it reaches maximum intensity. IT is one of the first images with an eye. This image really shows how the eye forms from spiral bands (seen in the darker blue shades) cut off a clear region of sinking air. The eye is likely one pixel (so about 8 km).
