Isobar - Weather Atlas
2023年5月30日 · An isobar is a line of equal atmospheric pressure on a map or chart. Learn how to interpret isobars, their relation to wind direction, and their role in meteorology and aviation.
Upper Air Pressure Chart Explanation and Analysis
Learn how to read and interpret upper air charts, which show weather conditions at different levels of the atmosphere. The 500 mb chart represents the mid-troposphere, where many weather systems follow the wind flow and the jet stream.

NOAA's National Weather Service - Glossary
An isobar is a line connecting points of equal pressure in meteorology. Learn more about isobaric charts, isobaric process and other related terms from NOAA's weather glossary.
CHART COMPARISON - National Weather Service
Understanding pressure contour lines (isobars) is the key to interpreting the chart. Without understanding isobars, temperature advection, wind speed/direction and pressure distribution the surface chart can not be comprehended. Upper air charts are at a fixed pressure level; temperature, dewpoints and wind are reported from that pressure level.
