A short feather indicates 5 knots, while a larger one shows 10 knots. The direction in which the triangles point is the direction in which the front is moving. Weather symbols are graphical representations of a range of atmospheric conditions commonly used during meteorological forecasts to display current and predict future weather conditions. 448 commits. Temperature, pressure and winds are all in balance and the atmosphere is constantly changing to preserve this balance. On some weather maps, you may notice lines surrounding and encircling the "highs" and "lows." These lines are called isobars because they connect areas where the air pressure is the same ("iso-" meaning equal and "-bar" meaning pressure).

A col is the name for the area of light variable winds that lies between two neighbouring pressure systems. In terms of the wind direction, air moves around high pressure in a clockwise direction and low pressure in an anticlockwise direction, so isobars also tell us the direction and speed of the wind.
