What does isobar density mean?

Isobars are lines connecting points with the same air pressure on the map, and dense isobars indicate that the air pressure changes little in this area. In the weather system, the wind is formed from the high pressure area to the low pressure area. When isobars are dense, it means that the pressure field changes dramatically and the wind speed will increase. Therefore, the denser the isobar, the greater the wind force.

Dense isobars may also indicate that the weather system is complex, with multiple pressure centers and wind direction changes. At this time, it is necessary to take timely preventive measures according to the weather forecast, such as avoiding going out to sea and strengthening building safety inspection.
