When a parcel of air rises or descends without water vapor added to or removed from the parcel..
When a parcel of air rises or descends without water vapor added to or removed from the parcel,which one is constant?And which one is changing
Why?
absolute humidity,specific humidity,mixing ratio,actual vapor pressure,saturation vapor pressure,relative humidity

Why?
absolute humidity,specific humidity,mixing ratio,actual vapor pressure,saturation vapor pressure,relative humidity
翻译基本上就是楼上那个,但是如果你这个是meterology的话,如果我没猜错的话应该是问,一部分空气在水分不变的情况下,上升和下降,哪些下列哪些数值不改变?但是要注意在大气之中,elevation的变化要使空气的温度和体积改变,但是其所具有的内能不变.vapor pressure and saturation vapor pressure和温度有关,所以以下根据定义,只有specific humidity是常数,如果温度和体积改变了变的话其他都要变.
回答：
1.Absolute humidity on a volume basis is the quantity of water in a particular volume of air.
2.Relative humidity is defined as the ratio of the partial pressure of water vapor (in a gaseous mixture of air and water vapor) to the saturated vapor pressure of water at a given temperature.
3.Specific humidity is the ratio of water vapor to air (including water vapor and dry air) in a particular mass.
