Closely spaced isobars indicate large pressure changes over a small area and suggest strengthening winds.
Widely spaced isobars portray a "flat" or weak pressure gradient typical of light-wind situations.
Closely spaced isobars on a weather map indicate that they help the meteorologists forecast the weather.
Light winds
Widely-spaced isobars indicate low wind speeds.
Widely-spaced isobars indicate low wind speeds.
The closer the isobars = the higher the wind speed.
wind will be blowing HARD
Strong winds
High pressure: The isobars will be far apart. Low pressure: The isobars will be very close together.
Isobars on a weather map indicate areas of constant pressure. They circle areas of high or low pressure. Isobars themselves do not indicate weather, but are a tool for understanding large scale weather processes as related to pressure systems. However, if the isobars are close together, wind is expected.
High winds. The closer the isobars - the higher the wind speed will be.
Tightly-packed isobars portend strong winds (A+) answer a hat or scarf because of high winds
The isobars form layered rings on the weather map.The closer the layers of the rings are to eachother, the lower the air pressure in that area is. The further apart they are the higher the air pressure. The closer the isobars are, the stronger the wind is. The air pressure is also depicted by letters. In an area where the isobars show that it has a high pressure, a 'H' will be in the the centre circle. If there is low air pressure there will be an 'L'. Air pressure is the density of air molecules. High air pressure is heaps of air molecules close together. Low air pressure is when they are far apart. When the air pressure changes from high to low, wind is created.

On a weather map, the lines of equal pressure (isobars) also illustrate the pressure gradient or change of pressure per distance. The higher the pressure gradient, the higher the winds speed. Thus, when the isobars are close together, the gradient is high, and winds are higher than where the isobars are further apart. Wind can also be affected by local considerations, hills, valleys, and buildings can modify the gradient wind's direction and speed.

It means that there is a steep gradient, or pressure change, and strong winds.

Wind is caused by differences in air pressure from place to place. If you look at a weather forecast map, you should see lines of equal pressure, these are called isobars. If you see a large area of equal pressure, the winds in that area will be light, this is called an anticyclone. If you see an area with the isobars close together there will be strong winds there. In extreme cases usually in tropical areas where there is a high amount of power from the sun, the isobars will form a circle with a very low pressure in the centre, and a hurricane will be formed.
Signature Block. It is atleast four lines below the complimentary close.
On a weather map, high wind speeds are indicated where thin lines with arrows are spaced close together. This indicates strong winds and the direction in which they will move.
