Question 2809 Deck General
70% to passA tropical storm is building strength some distance from your MODU. Waves are coming from the east, with periods increasing from 5 seconds to 15 seconds. The swell is from the east. Where was the storm when these new swells were generated?
A
To the north of you
B
To the east of you
C
To the west of you
D
To the south of you
AI Explanation
The correct answer is B) To the east of you. The increase in wave period from 5 seconds to 15 seconds indicates that the storm generating the swell is located to the east of the MODU. Longer period waves are generated by distant storms, and the direction of the swell is an indicator of the storm's location relative to the MODU. The other options are incorrect because a storm to the north, west, or south would not generate the observed eastward swell. The location of the storm relative to the MODU is determined by the direction of the swell, not the direction of the waves themselves.
