GEOLOGY

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: -High-pressure system High-pressure systems are frequently associated with light winds at the surface and subsidence through the lower portion of the troposphere. In general, subsidence will dry out an air mass by adiabatic or compressional heating. Thus, high pressure typically brings clear skies.

Detailed explanation-4: -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. It forms tiny water droplets, making clouds in the sky.

Detailed explanation-5: -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.
