Different weathers
Low Pressure Systems
High Pressure Systems
Low Pressure: Also known as:
• Lows
• Depressions
• Cyclones
(Pressure is lowest in the centre)
High Pressure: Also known as:
• Highs
• Anti-cyclones
Weather of a low pressure system:
Strong Winds (blowing in towards the
centre)
Much cloud (caused by warm air rising
and condensation)
Much Precipitation (condensation causes
clouds which usually leads to rain.)
Weather of a high pressure system:
Light winds (blow away from the centre)
No cloud (no ascending air, no
condensation, no cloud)
Dry weather (less clouds = less rain)
(Pressure is highest in the centre)
