Question 944Navigation General
70% to passWhat is the average speed of the movement of a hurricane following the recurvature of its track?
A
Over 60 knots
B
5 to 10 knots
C
20 to 30 knots
D
40 to 50 knots
AI Explanation
The correct answer is C) 20 to 30 knots. After a hurricane recurves, it typically increases in forward speed, with average speeds in the range of 20 to 30 knots. This is because the hurricane has transitioned from a tropical system that is steered by low-level wind patterns to an extratropical system that is steered by upper-level wind patterns, which tend to move faster. The other options are incorrect because A) over 60 knots is too fast for the average speed of a hurricane after recurvature, B) 5 to 10 knots is too slow, and D) 40 to 50 knots, while faster than the correct range, is still not the average speed typically observed.
