Synoptic Chart Wind Direction

Cold fronts and warm fronts. Isobars are lines joining points of equal pressure, similar to contours, which are shown on weather charts. 0 % isobars and wind direction.

When isobars are close together the pressure changes quickly. The need for synoptic charts. The steeper the pressure gradient, the faster air will move from high to low pressure areas, thus.

These can be found by looking for a big number, like 1020mb in the centre of a loose circle on a weather chart.

This simple feature of synoptic charts allows us to determine the likelihood of snow based on all the other information the chart shows us like wind direction and frontal systems. The weather map, also known as a synoptic (summary or overview) chart, is a simple representation of the weather patterns at the earth's surface, showing the locations and movements of the different systems. Therefore a wind direction of 180 is blowing from the south. Isobars close together strong winds back next.
