PRECIPITABLE WATER IN A SATURATED PSEUDOADIABATIC 

 ATMOSPHERE 



327 



If all the water vapor in a column of air were precipitated, the depth of water which 

 would accumulate is defined as the depth of "precipitable water" of the column. The 

 chart 1 below gives the precipitable water (inches) of a column between the 1000-mb. 

 surface and any pressure surface aloft in a saturated pseudoadiabatic atmosphere 

 (Table 78) as a function of the 1000-mb. temperature of the pseudoadiabat (pseudo-wet- 

 bulb potential temperature, °C. or °F.). Altitude lines represent heights above the 

 1000-mb. surface in a pseudoadiabatic atmosphere.
