Question

If a hurricane with 90 kt maximum circulation (in a reference frame moving with the cyclone) is moving straight northwest at 10 kt, (i.e., 7 kt northward and 7 kt westward, 72 + 72 = 98 102 ) 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. North of the center________ c. East of the center_________

b.South of the center________ d. West of the center _________?

Explanation / Answer

Answer- Hurricane forms in the low pressure in a tropical climate. wind moves from the region of high pressure to low pressure, it rotates in the anticlockwise direction in the Northern Hemisphere and clockwise in the southern hemisphere. Center region of the hurricane or tropical cyclone called Eye. it is the region of low pressure it is characterized by the calm atmospheric condition with low wind velocity. the maximum velocity of winds in the hurricane is sustained in the eyewall

here given maximum wind speed is 90knot, moving straight northwestard with 10knot

so the maximum velocity of the wind the north of center is 90+10= 100knot

the maximum velocity of the wind the south of the center is 90-10 = 80knot

the maximum velocity of wind is the east of the center is 90-10 = 80 knot

maximum velocity of wind is the west of the center is 90+10 =100knot
