Question

As was seen at the 500-mb constant-pressure level in Investigation 8B, higher wind speeds at 300 mb are also located where the spacings of height contours are generally relatively ________. Furthermore, the relationship is consistent with that on surface weather maps between wind speeds and the spacings of isobars.

1. Even
2. Narrow
3. Tight
4. close together

Answer 1

Higher wind speeds at the 300 mb level occur where height contours, as well as isobars on surface weather maps, are spaced closely together, indicating a steeper pressure gradient and leading to stronger winds.

Step-by-step explanation:

The answer to the question regarding higher wind speeds at the 300 mb constant-pressure level in relation to the spacing of height contours is that they are located where the spacings of height contours are generally close together. This is parallel to the observation on surface weather maps, where wind speeds are higher when the isobars are close together. A smaller distance between isobars or height contours indicates a steeper pressure gradient, which results in stronger winds.
