How do pressure differences effect wind speed?

Answer 1

Diverging wind helps evacuate air from a region, thus lowering its pressure.

However, diverging wind at the surface is associated with high pressure, because air is converging aloft and subsiding, whereupon it reaches the surface and spreads out.

Answer 2

The greater the pressure difference over a given distance the greater the wind velocity. Think of the earth's atmosphere as mountains and valleys of stacked molecules of air. The air flows from the high pressure areas (mountains) to the valleys (areas of low pressure). On weather maps the barometric pressures are shown by lines that depict points on earth at the same barometric pressure. These are called isobars... a contraction for iso (same) and bars (barametic pressure). At the adjoining areas of higher or lower pressure, another isobar line is drawn. The closer together the isobar lines are the steeper the pressure gradient indicating higher winds. It is somewhat analogous to the contour lines shown on a geologic map.

Answer 3

The thing about wind is that it'll always travel from a high pressure system to a low pressure system.

The high pressure system pushes air out away from the system, which also plays a role of not allowing for cloud formation. On the other hand, the low pressure system takes air in and allows for cloud formation, which is just another role how we get storms from mainly low pressure system. We won't always get storms from low pressure systems. Some storms can be lake-effect, but they come off large lakes like Lake Michigan, Superior, Erie, Huron, or Ontario.

Answer 4

Low pressure systems form under areas of wind divergence which occur in upper levels of the troposphere.

Answer 5

Air will always try to flow from a high-pressure area to a low-pressure one. The greater the pressure difference - the higher the wind speed.

Answer 6

Go do your homework kiddo.
