DYNAMIC METEOROLOGY AND HYDROGRAPHY. 



Table 16 T&.. Temperature corrections for the extrapolation of virtual-temperature 



diagrams [based upon statistics). 



Belo-v the earth's surface. 



Examples. 



(1) Spring, mean pressure. Required the virtual temperature 1761 



dynamic meters above the earth's surface : 



Given virtual temperature at the earth's surface 4-12-8 



Table 16 gives for spring, mean pressure, 1761 dynamic 



meters 8.2 



Required virtual temperature 4- 4.6 



(2) Summer, high pressure. Height of station 391 dynamic meters above 



sea-level. Virtual temperature at the station +7.1. Required the 

 virtual temperatures in standard heights. These are found as shown 

 in the annexed scheme.
