Detailed explanation-1: -High pressure systems are generally associated with warm and dry conditions. Low pressure systems take the air at the surface and force it up high into the atmosphere. This process causes air to cool and condense, which is how we get clouds. Thunderstorms and winter storms are associated with low pressure systems.
Detailed explanation-2: -A high-pressure center of dry air is called an anticyclone. Winds move in the clockwise direction around high-pressure centers. This is due to the effect of the Earth spinning on its axis. When cool air sinks, it reaches the Earth’s surface and moves out parallel to the ground.
Detailed explanation-3: -High pressure systems can be cold or warm, humid or dry. The origin of a high-pressure region determines its weather characteristics.
