Detailed explanation-1: -A low-pressure system usually brings clouds and precipitation, while a high-pressure system brings cool dry air and clear skies. A low-pressure system usually brings warm dry air and clear skies, while a high-pressure system usually brings warm moist air and precipitation.
Detailed explanation-2: -A high pressure system is associated with cooler temperatures and clear skies. A low pressure system is associated with warmer weather, storms or precipitation.
Detailed explanation-3: -In a depression (low pressure), air is rising and blows in an anticlockwise direction around the low (in the northern hemisphere). As it rises and cools, water vapour condenses to form clouds and perhaps precipitation.
Detailed explanation-4: -Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward toward these areas. This causes air to rise, producing clouds and condensation. Low-pressure areas tend to be well-organized storms.
