DYNAMIC METEOROLOGY AND HYDROGRAPHY. 



Table 17 M (continued). Change of topographic charts of isobar ic surfaces into isobar ic 



charts in level surfaces. 



III. Height of the Soo m-bars Surface (Dynamic Meters). 



IV. Height of the 700 m-bars Surface (Dynamic Meters). 



Example 2. Given the topographic and the isothermic chart of the 700 m-bars surface. Required the isobaric 

 chart in level 3000 dynamic meters. 

 Table 17 m (rv) shows that 



The isobaric curve 700 m-bars is identical with the level curve 3000 dynamic meters. 



The isobaric curve 695 m-bars goes through the points of intersection of the isothermic curve 60 C. with 

 the level curve 2956 dynamic meters ; of the isothermic curve 50C. with the level curve 2954 

 dynamic mtters: and so on. 

 The isobaric curve 690 m-bars goes through the points of intersection of the isothermic curve 60 C. 

 with the level curve 2912 dynamic meters ; of the isothermic curve 50 C- with the level curve 

 290S dynamic meters ; and so on.
