How to read a weather map H = high pressure, L = low pressure

Isobars are labeled with a number = air pressure (hectopascals)

Air pressure is higher near the centre of a high pressure weather system

Air pressure is lower near the centre of a low pressure system

Isobars that are closely spaced mean strong winds (low pressure systems)

Isobars that are spaced far apart indicate calm weather (high pressure systems)
