Difference Between Low and High Pressure Systems | …

2013/2/23· The key difference between low and high pressure systems is that low pressure systems are zones where the air is rising while high pressure systems are zones where the air is sinking. More importantly, low pressure systems create moist weather, cloudy conditions, and changing weather, whereas high pressure systems support low humidity, dry and warm, fair weather.
