Yearly Variations of Terrestrial Phenomena and Solar Activities. ^5 



mentary to Type III, the middle and the external sectors being 

 occupied with the years of minimum temperature. An example 

 is given in Fig. 14. 



These results led me to revise the pressure diagrams and to 

 examine if a similar quadruple classification is not possible also in 

 that case. It was found that the marked sinuousity of the lines of 

 demarcation could be avoided in some cases if we allow the ex- 

 istence of the four analogous types. On carrying out the revision, 

 it was found however that the new classification affects the zonal 

 distribution of the Map of Fig. 1 in no considerable way, if we 

 take Types III and IV as the general cases of Types I and II 

 respectively, as is quite natural, and denote them by the same mark 

 O and X respectively. 



3) Relation between Pressure and Temperature. 



The relation between the pressure types and the temperature 

 types is of the paramount importance for the investigation of the 

 cause of the fact disclosed above. It is especially interesting to 

 see whether high pressures correspond to high or low temperatures. 

 For this purpose, the correspondence of pressure and temperature 

 types was examined for all stations for which the determination of 

 the type was possible for the both elements. Among the eighty 

 seven stations available, fourteen were put aside, as the classifica- 

 tion was more or less ambiguous. In forty six^^ among the 

 remaining seventy three stations, I or II pressure type is associated 

 with II or I temperature type respectively, while in twenty seven 

 stations^^ the contrary relation is found. It ma}" be observed that 

 of the latter twenty seven stations, eighteen are those belonging
