Our atmosphere is divided into layers of air which exerts pressure on the ground, at the earth. The higher the distance from the ground, lower the pressure of the air exerted by it. (i.e why astronauts float above the atmosphere with no pressure or gravitation pull). Atmosphere gets heated up by the sun and so the ground. This causes the moisture to evaporate and the air above the ground becomes warmer and both rise up. Warmer air are less dense, lighter in weight and have a tendency to hold more water. This warmer air rises up above the cold air (which is heavier or highly denser). The areas which witness such type of phenomenon are called as low pressure areas. At a later stage, the warmer or low pressure air, above the cold high pressure air, gets cooled, condensed and causes precipitations. Low pressure air is usually marked with cloudy and windy sky. Hence we say that Low pressure areas gets torrential rainfall. Whereas in high pressure areas, one would witness dry and clear sky (due to lack of condensed air or clouds)
Low pressure
Air.
Winds are typically stronger near a low pressure area because air flows from high pressure to low pressure, creating faster wind speeds. In contrast, near a high pressure area, the air is descending and spreading out, resulting in lighter winds.
Diffusion occurs when an area of high pressure meets an area of low pressure. They mix together and create an equilibrium, all particles spread out equally.
Air mass - refers to any area of high or low pressure. A front - is the point at which an area of high pressure meets an area of low pressure.

low
high pressure most likely
an area of high pressure to an area of low pressure. This movement occurs naturally as the atmosphere seeks to equalize pressure imbalances. The flow of air from high to low pressure is what creates our wind patterns.

Wind
High pressure means there is going to be rain in that area. Low means the opposite.
