EVERYDAY SCIENCE

Detailed explanation-1: -High pressure generally means clear skies and drier conditions. In contrast, low pressure generally means some sort of precipitation.

Detailed explanation-2: -High pressure often means dry weather with sunshine. Low pressure often means clouds and precipitation. High pressure is associated with sinking air.

Detailed explanation-3: -Under high pressure you can generally expect sunny skies and calm weather. Low pressure is what causes active weather. The air is lighter than the surrounding air masses so it rises, causing an unstable environment. Rising air makes the water vapor in the air condense and form clouds and rain for example.

Detailed explanation-4: -Stormy Conditions. High and low pressure systems produce opposing weather conditions. High pressure systems are generally associated with fair weather, while low pressure systems bring clouds, precipitation and sometimes stormy conditions.

Detailed explanation-5: -High pressure days generally have clear skies because sinking air prevents clouds from forming. Low pressure causes air to flow up slowly. As air rises, it cools and water vapor within the air is unable to remain a gas.
