How: Dry air (~79% Nitrogen, ~20% Oxygen) is heavier than water vapor (H20) Dry air mixed with water vapor is lighter than pure dry air High water vapor/high humidity = drops in barometric pressure Also: High pressure areas next to low pressure areas will lead to lots of wind Sudden pressure drops also signal a tornado for example Clear skies/weather is seen by higher pressure or an increase of ~3 kPa Issues: Weather prediction also is dependent on humidity and wind direction App Note AN3914 AnalysisOutput dP > +0.25kPaSun Symbol -0.25kPa >dP >0.25kPaSun/Cloud Symbol dP <-0.25kPaRain Symbol Pcomp (MPL115A Pressure) (kPa) PWeather (Ideal weather) (kPa) SimpleweatherdiffWeather type 96.696.85-0.25Sun/Cloud 96.496.85-0.45Rain 97.496.850.55Sun 96.9296.850.07Sun/Cloud Example:
