indicate clearly the principles that are involved in their structure. 
Continuing the computations to higher levels, it is found that the 
temperature lines or isotherms, the pressure lines or isobars, and 
the velocity lines or vectors, coincide at every point in direction. 
In the lower levels these lines cross each other at various angles 
in the areas marked 1 to 26 on the sea level of Fig. 12, which 
shows the order of the computations : (1) The upper undisturbed 
circulation, where T. P. q coincide, belongs to the general 
circulation, and (2) the lower disturbed circulation, where 
T. P. q do not coincide, to the combined general and local circula 
tion; (3) the purely local circulation, the cyclone and anti 
cyclone proper, can be separated from the second by vector 
composition, since (2) is the resultant of (l) and (3). It is 
found that the disturbing circulation (3) is similar in configuration
