1. Different weathers

2. Low Pressure SystemsHigh Pressure Systems Low Pressure: Also known as: Lows Depressions Cyclones (Pressure is lowest in the centre) High Pressure: Also known as: Highs Anti-cyclones (Pressure is highest in the centre) 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)
