When isobars on a weather map are very close together, it indicates a steep pressure gradient in that area. A steep pressure gradient results in stronger winds because the pressure difference between adjacent areas is significant. As a consequence, the winds will flow rapidly from the high-pressure area to the low-pressure area, exhibiting strength.

In addition to being strong, these winds will tend to cross the isobars at an angle rather than flow directly along them. This behavior is largely influenced by the Coriolis force, which causes moving air to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Therefore, while the surface winds are strong due to the close spacing of isobars, their movement across the isobars showcases the dynamics governing wind behavior in response to pressure differences.

Other options describe weak, erratic, or moderate winds, which do not align with the increased wind speeds associated with closely spaced isobars. Wind characteristics typically become weaker where isobars are further apart, leading to a lack of significant pressure differences that would generate strong winds.
