Answer 1

A high pressure center is characterized by descending and diverging air at the surface, leading to clear skies and stable weather. Weather maps illustrate these with a blue 'H' and grey isobars to denote areas of constant pressure.

Step-by-step explanation:

A high pressure center is generally characterized by descending air that diverges at the surface. As the air descends, it warms and inhibits cloud formation, often leading to clear skies and relatively stable weather conditions. Meteorologists use weather maps to predict weather, identifying these high pressure areas with a blue 'H' on maps. The areas around these high pressure centers are marked with grey lines called isobars, which represent locations of constant pressure. A large difference in pressure between two areas can lead to storm reports, as seen in the 2008 Super Tuesday tornado outbreak. High pressure regions have significant effects on weather and are superimposed on regular atmospheric circulation patterns, affecting both Earth's climate and other planetary atmospheres like those of Jupiter and Neptune.

Answer 2

A high pressure center is generally characterized by cool, dry weather. The movement is cause by the addition of forces due to gravity because their higher pressure compresses the column of air near the center of the area nto greater density and so greater weight compared to lower pressure, lower density and lower weight of the air outside the center.
