Is it true that there is less humid in the air in the winter compared to other three seassons, why?
It is NOT true there is less humid [sic] in the air in the winter compared to other three seassons. The relative humidity (RH) can be 100% in winter when the dew point is 30°F. The RH can be 100% in spring or fall when the dew point is 50°F. The RH can be 100% in summer when the dew point is 70°F. There's more water vapor in the air at 70°F than there is at 30°F; yet both can have an RH of 100%. --- Evey other answer in this thread is clueless.
Yes,because its colder.Humid normally means the air feels thick and heavy with moisture.Winter is colder,so this moisture freezes and falls to the ground.
Yes. Warm air can hold more moisture than colder air.
Not always, but yes. High pressure weather systems often ha s colder air with less relative humidity, while low pressure weather systems with warmer air have higher humidity. However, in warmer and more humid areas of the US, like New Orleans, fog is a big problem. For people who commute tithe north shore if Lake Pontchartrain, they are escorted by levee board police along the Causeway twin bridges. It did not used to to be two bridges. Lake Pontchartrain may. It be deep, but people drown in it every year.
the cold condenses the humidity/moisture OUT of the air ..............................
