Light winds
Widely-spaced isobars indicate low wind speeds.
Generally it means good weather, as it indicates an anticyclonic system. Anticyclonic systems bring calmer, more settled weather.

How do you determine where the strongest winds are on a weather map?
The barbs are arrows pointing in the direction wind blows from. They have little points (barbs) off the side of them. A full barb represents 10 knots, a half barb represents 5 knots, and a flag represents 50 knots. You add the numbers represented by the number of full and half barbs. Thus 2 full barbs and 1 half barb represents a 25 knot wind. To convert knots to MPH multiply the knots by a factor of 1.15.
Are air particles of sound far apart or close together?
high sound particles are near, and low sound as far apart particles.
Gravity depends on how far -------- andhow -------- the objects are?
Gravity can depend on how far apart and how heavy the objects are.
How do isobars measure air pressure?
Isobars are not measured. An isobar describes a part of a thermodynamic process during which the pressure doesn't change. It is also used as a term in graph tables where it describes the behavior of a material at a constant pressure.
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.
Widely spaced isobars often indicate?
Widely spaced isobars often indicate lower wind speeds and generally calm weather conditions. This is because the pressure gradient is weak when isobars are far apart, resulting in less atmospheric pressure change over a given distance.
Contour lines that are far apart indicate?
Contour lines that are far apart indicate gradual slopes, while contour lines that are close together indicate steep slopes.
You can locate regions of low wind speed on a weather map by locating what?
You can locate regions of low wind speed on a weather map by identifying areas with closely spaced isobars or lines of constant pressure. In areas where the isobars are spaced far apart, wind speeds tend to be lower. Additionally, calm conditions and light winds are often associated with high pressure areas.
Which would show stronger winds widely spaced isobars or closely spaced isobars?
Closely spaced isobars typically indicate stronger winds, as the pressure gradient is stronger in this case. Widely spaced isobars indicate weaker winds with a weaker pressure gradient.
How do you read isobars?
Isobars are lines on a weather map that connect points of equal atmospheric pressure. They are read by looking at the spacing between the isobars: the closer they are together, the stronger the pressure gradient and therefore the stronger the winds. The direction of the isobars can also indicate wind flow, with the wind flowing perpendicular to the isobars from high to low pressure.
How do you determine low pressure and high pressure using isobars on a weather map?
On a weather map, low pressure is typically indicated by closely spaced isobars, while high pressure is indicated by widely spaced isobars. Low pressure systems are associated with stormy weather, while high pressure systems are associated with fair weather. The closer the isobars are together, the stronger the winds will be.
On topographic maps contour lines that are far apart indicate?
On topographic maps, contour lines that are far apart indicate gentle slopes or gradual changes in elevation. The farther apart the contour lines, the flatter the terrain.
What does close spacing of isobars on the weather map represent?
Close spacing of isobars on a weather map indicates strong pressure gradient and high wind speeds. This means that the difference in air pressure over a short distance is large, resulting in stronger winds. This often leads to windy and potentially stormy conditions in that area.
What kind of topography does contour lines that are far apart indicate?
Contour lines that are far apart indicate a gentle slope. Because contour lines connect points with the same elevation, wide spacing indicates that the elevation is not changing drastically.
What is indicated when contour lines are far apart on a topographic map?
When contour lines are far apart on a topographic map, it indicates a gentle slope or flat terrain. The spacing between contour lines represents the steepness of the terrain, with wider spacing indicating a more gradual slope.
What lines do meteorologists draw?
Meteorologists draw lines to indicate air pressure, which are called isobars.
Are contour lines closely spaced or far apart to indicate steep hills?
Closely spaced
