19b 



Table IIM (continued). Distances in dynamic meters from the earth's surface to the nearest standard 

 isobar ic surface, the average virtual temperature of the sheet being o C. 



Dynamic 

 Example : meters. 



Height of station above sea level 39 



Table 11 M gives for the 1000 m-bar surface and the pressure of 10 15. 9 at station -J- 1 23 



Virtual-temperature diagram giving for the sheet between the station and the 1000 m-bar surface the average 



virtual temperature +25 , table 12 M gives for this temperature and the height 123 the correction + n 



Height of standard surface 1000 m-bars above sea level 173
