70% to passThe dangerous semicircle of a typhoon in the Southern Hemisphere is that area _______________.
A
ahead of the typhoon measured from the storm's track to 90° on each side
B
to the left of the storm's track
C
measured from due south counterclockwise 180°
D
measured from due south clockwise 180°
AI Explanation
The correct answer is B) to the left of the storm's track. In the Southern Hemisphere, the dangerous semicircle of a typhoon is the area to the left of the storm's track. This is due to the counterclockwise rotation of the storm system, which means that the strongest winds and most hazardous conditions are found in the left-hand side of the storm, relative to its direction of movement. The other answer choices are incorrect because A) refers to the dangerous quadrant in the Northern Hemisphere, C) and D) do not accurately describe the location of the dangerous semicircle in the Southern Hemisphere.
