Areas of equal pressure and winds?

Question

Why do winds in a smaller area of equal pressure go faster as compared larger area of equal pressure?

Answer 1

eyeonthescreen,
That has to be the BEST explanation I have ever read (in layman's terms)
I intend to use your explanation in my next ground school!!!!
You will get my vote when allowable.

Answer 2

Pressure gradients (changes in pressure) cause winds. It's something like a waterfall. The pressure gradient is something like the cliff the water tumbles over. The higher and steeper the cliff (the greater the gradient), the faster the water tumbles, which is like stronger winds blowing.

When the cliff is a gentle slope, that's like the water coming downhill in a stream. It will speed up, but not nearly so fast as if were coming down a steep cliff that drops almost straight down. In a similar way, the slope of the pressure gradient determines the velocity of the winds.

Thus, over small areas, the slope of the gradient is steeper than an equivalent gradient over a large area. So when you see the isobars on a weather map up close to each other (i.e., over a small area), that indicates a steep slope and high winds for the pressure gradient. When you see the same isobars far apart from each other (i.e., over a wide area), that indicates a shallow slope and lower winds for the same gradient.

Good question.

Answer 3

ERMMM

Wind is caused by air moving from high pressure areas to low pressure areas.

In constant pressure there is no wind.

Answer 4

'Winds blow from High to Low'
