The correct answer is B) 30% to 40% of mid-winter winds are from a northern quadrant. This is correct because during the mid-winter months in the Gulf Coast area, the prevailing wind direction is typically from the north. This is due to the influence of cold fronts and high-pressure systems that move down from the northern United States during the winter season. The other answer choices are incorrect because A) the winds are not necessarily strongest in March, C) 40-50% of mid-winter winds are not from the southern quadrant, and D) this statement does accurately describe the prevailing wind direction in the Gulf Coast area during mid-winter.
