The navigable semicircle of a typhoon in the Southern Hemisphere is the area _______________.

A behind the typhoon, measured from 90° to 180°From each side of the storm's track
B to the right of the storm's track
C measured from due south, counterclockwise 180°
D ahead of the typhoon, measured from the storm's track to 90° on each side
AI Explanation

The correct answer is B) to the right of the storm's track. In the Southern Hemisphere, the navigable semicircle of a typhoon is the area to the right of the storm's track. This is because in the Southern Hemisphere, the winds circulate counterclockwise around the center of the storm. The navigable semicircle is the safer side of the storm, where the winds are blowing away from the center rather than towards it. The other options are incorrect because they do not accurately describe the location of the navigable semicircle in the Southern Hemisphere. Option A describes the navigable semicircle in the Northern Hemisphere, while options C and D do not correctly identify the 180-degree area to the right of the storm's track.
