how does pressure affect weather
Quick Answer. Air pressure affects the weather by influencing the movement of air around the planet; areas of low pressure generally develop clouds and precipitation, while areas of high pressure tend to bring clear, sunny weather conditions. Air pressure refers to the force exerted by the atmosphere on the surface of the Earth.
Whether large or small, when air parcels meet, we get fronts. The differences in the temperature, pressure, density and moisture content of the air masses makes one front slide over the other one, which can affect weather patterns by creating cloudy skies, thunderstorms and gusty winds.
