Question

2. If a hurricane with 85 kt maximum circulation (in a reference frame moving with the cyclone) is moving straight northwest at 10 kt (i.e., 7 kt westward and 7 kt northward) what is the strongest value of the wind relative to the sea surface at each of these locations in the eyewall relative to the center. Here we are looking for the swirling (tangential) component of the wind. Neglect any radial (in or out) component due to the motion.

a. Northwest of the center________ c. Northeast of the center_________ b. Southeast of the center________ d. Southwest of the center _________?

Explanation / Answer

St = FL/V gives the strength of the wind

to find L we use Reynolds no.as   Re = VL/v  

v is kinematic viscosity

as the wind travels in northwest direction, it can be deviated towards the eye wall

Hence the driection is would be north west, option A
