Question 1028Navigation General
70% to passWhen drawing a weather map and an isobar crosses a front, the isobar is drawn _______________.
A
perpendicular to the front
B
kinked and pointing towards the low
C
kinked and pointing away from the low
D
kinked and pointing towards the high for a warm front only
AI Explanation
The correct answer is C) kinked and pointing away from the low. When an isobar crosses a front, it becomes kinked to indicate the change in wind direction across the front. The isobar kinks and points away from the low pressure system, as the wind flow changes direction. This is due to the difference in air masses on either side of the front. The other options are incorrect because: A) the isobar should not be perpendicular to the front, B) the isobar points away from the low, not towards it, and D) the kinking of the isobar is not dependent on the type of front (warm or cold).
