what is a weather Map?

Posted in Weather Maps

Weather Map is typically a graphical representation of various factors involving atmospheric conditions such as wind strength/direction diagrams, Temparature maps, Low/High Pressure indications etc.

Wind strength is inversely proportional to the distance between isobars — the closer the lines, the stronger the winds. This rule does not apply in the tropics where the effect of the earth’s rotation is weak. For this reason, tropical meteorologists usually replace isobars with streamline arrows which indicate wind and direction without directly relating to the pressure gradient.

Shaded areas on weather maps show where there has been rain in the previous 24 hours, and wind direction is shown with arrows that have a series of barbs on their tails to indicate speed.
