The amount of clouds in the sky is a strong indication of the level of pressure in a given area. This is because areas that are influenced by high pressure usually have few clouds and, at times, have no cloud at all and therefore have little or no probability of precipitation.
On the other hand, areas with low pressure influence present high cloudiness, with a strong presence of clouds. These areas are often called the cold front and have a high chance of precipitation.
A high-pressure area, high or anticyclone is a region where the atmospheric pressure at the surface of the planet is greater than its surrounding environment. Winds within high-pressure areas flow outward from the higher pressure areas near their centers towards the lower pressure areas<span> further from their centers.</span>
