10 READING BETWEEN THE LINES Isobars – the lines you see on a weather chart – show the lines of equal atmospheric pressure. This in itself may not sound very exciting, but those lines contain a host of information about the weather. The lines connect places where equal barometric pressure is found or forecast, depending on the type of chart, and they form the basis of any weather forecast. Although they represent the atmospheric pressure, they are also the main indicator of wind strength and direction as well as showing the location of fronts, which can have a significant effect on the weather you will experience.

Because most weather charts are based on a Mercator projection similar to that used for most navigation charts, there will be distortion of the scale that will vary with latitude. This means that the distance between the isobars relating to an associated wind strength will also vary with latitude. To enable you to relate the distance between the isobars to the associated wind strength, the weather chart is provided with a scale. To find the related wind strength, measure the distance between the isobars in your location and read off the wind strength that relates that distance to your latitude.

These inconsistencies can take three forms. The shortest-term are the temporary gusts and lulls that occur when the wind increases or decreases briefly around the average. These are nearly impossible to forecast, and while they are more likely to be found close to land, they can also be experienced in the open sea. The potential doubling of the wind speed in a gust can be a significant factor for sailboats. Another form of inconsistency occurs in association with rain squalls or thunderstorms, which can also be very localised.
