Hurricane Francoise is approaching Martinique from the east. At 1000 GMT on Friday the 13th Francoise is 400 nautical miles (n.mi.) away and is traveling westward at 15 knots. The NOAA hurricane-hunter aircraft in which you are flying measures a central pressure in Francoise of 967 mb and air temperature of 28 degrees Celsius at the surface using a dropsonde. As you cross the eyewall, 25 n.mi from the center of the eye, the central pressure rises 10 mb in a horizontal distance of only 15n.mi.
a) Calculate the radial winds at the surface in the eyewall
b) Forecast when the center of Francoise's eye will pass over the island
c) How do you sketch the wind speed and direction of the semicircle
d) Using a wave nomograph, what is the significant wave height, and period
e) On the Saffir-simpson scale, what is the category of the hurricane?
f) What is the IBE and Storm Surge at 10m water dept
