here are the dfinitions its not that hard to come up wih something.
Pressure gradient-n atmospheric sciences (meteorology, climaxtology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes which direction and at what rate the pressure changes the most rapidly around a particular location. The pressure gradient is a dimensional quantity expressed in units of pressure per unit length. The SI unit ispascal per meter (Pa/m).
Isobars-A line on a map connecting points having the same atmospheric pressure at a given time or on average over a given period.

The closer the isobars are together?
the steeper the pressure gradient
Why some winds are stronger than others?
On a field map, the winds are the strongest when the isobars are very close together, and the pressure gradient is high.
How do you determine low pressure and high pressure using isobars on a weather map?
High pressure: The isobars will be far apart. Low pressure: The isobars will be very close together.
What does close spacing of isobars on the weather map represent?
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.
What is the purpose of isobars?
Isobars show different pressure areas on a weather map.
The closer the isobars are together?
the steeper the pressure gradient
Where on a weather map wind speeds are related to?
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.
What are Isobars and what does it mean when they are close together?
It means that there is a steep gradient, or pressure change, and strong winds.
Which would show stronger winds widely spaced isobars or closely spaced isobars?
Closely spaced isobars mean stronger winds, as it indicates a tight pressure gradient.
What happens to pressure and isobars in cyclones and in anticyclones?
The isobars become concentric and sometimes, especially in cyclones, tightly packed with low pressure in the cyclones and high pressure in the anticyclones. In the more intense systems the isobars may be almost perfectly circular.
Why are winds stronger than others?
On a field map, the winds are the strongest when the isobars are very close together, and the pressure gradient is high.
Why do jet streams flow parallel to isobars?
Because jet streams are above the friction layer, they have a negligible effect. The wind is balanced by the Coriolis effect and the pressure gradient so that the winds flow parallel to isobars.
Why some winds are stronger than others?
On a field map, the winds are the strongest when the isobars are very close together, and the pressure gradient is high.
Is it true or false that an anticyclone the value of the isobars increases from the center to the outside?
False. Pressure decreases from the center to the outside.
What does a steep air pressure gradient cause?
high winds
How do you determine low pressure and high pressure using isobars on a weather map?
High pressure: The isobars will be far apart. Low pressure: The isobars will be very close together.
What kind of map might diagrams of air pressure?
A diagram of air pressure could be represented on a weather map. This map would use isobars - lines that connect areas with the same atmospheric pressure - to show areas of high and low pressure. The spacing of the isobars indicates the strength of the pressure gradient, which affects wind speed and direction.
