Table 14 A (continued). Distances in dynamic meters from the earth's surface to the nearest standard 

 isobaric surfaces., the average virtual temperature of the sheet being C. and the pressure at 

 the station being given in niillinieters of mercury. 



Dynamic 

 Example : meters. 



Height of station above sea- level 39 



Table 14A gives for the 1000 m-bar surface and the pressure at the station of 762.0 mm 123 



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

 perature -|- 25; table 12 m gives for this temperature and the height 123 the correction + 11 



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