3 important questions on Air - Wind - High pressure and low pressure - isobars
How do you identify a high pressure area?
In a high pressure area the air pressure is higher than the pressure elsewhere. The weather in that area is generally calm and sunny. In spring and autumn there is a risk of fog.
How do you identify a low pressure area?
In a low pressure area the air pressure is lower than the pressure elsewhere. When a low pressure area occurs, we have changeable weather, with a lot of wind and precipitation.
How do you know if we are going to get nice weather of bad weather?
If the air pressure rises we will get a high pressure area, therefore we will get nice weather. If the air pressure drops, we will get a low pressure area and the weather will get worse.
