La intensidad del viento:The speed or strength of the wind:
Show the answer
Correct answer: a) Depends on the barometric gradient: the closer together the isobars, the stronger the wind.
Why it is correct
Wind speed is directly proportional to the horizontal pressure gradient: the closer together the isobars on the chart, the steeper the gradient and the stronger the wind.
Why the others are not
- b) Widely spaced isobars mean a weak gradient and light winds.
- c) Hydrostatic pressure acts underwater, not on the wind.
- d) Neither hydrostatic pressure nor salinity drives the wind.
How to work it out in the exam
- Closely packed isobars = steep pressure gradient = strong wind.
