DYNAMIC METEOROLOGY AND HYDROGRAPHY. 



On the other hand, we can choose dynamic height as argument and register 

 temperature, density, and pressure for certain standard heights. This is made 

 in table F, the four sections of the table representing the same four cases as in 

 table E.

The two tables show essentially different features. The first has the important 

 property of being finite, which gives a great practical advantage, while the second 

 continues infinitely to infinite heights. It is important to remark also that the 

 division of the atmosphere into isobaric sheets, as in table E, represents practically 

 a division into sheets of equal mass, and thus, from certain points of view, of equal 

 importance, while the division into equipotential sheets as in table F corresponds 

 to a division into sheets of decreasing masses upward, and thus of decreasing 

 importance.
