Most important for understanding atmospheric pressure is knowledge of the variations it is subjected to under the influence of various factors.
When we have an atmospheric pressure higher than 1013 Mb or hPa (high pressure or anticyclone) it is why the air is heavier, coming down colder and drier and gives us a good clue to say we can have a good time and / or cold.
The centers of high atmospheric pressure generate divergent air movement out of the center and also subsident (top to bottom) causing the air to become drier. High pressure plays the opposite role of low pressure: it dries the air, decreases cloudiness and conditions for rain.
