sections along the lake, according to the canal theory. Figure 192 shows 

 a clockwise rotation of the M 2 high water around Lake Baikal, but with 

 extraordinarily rapid transitions in the centre of the lake. Therefore, the tide 

 wave corresponds almost exactly to a standing wave with the phase 21 h 

 at the south-west end and a phase of 7 h at the north-east end. A com-

Fig. 192. Theoretical M 2 tide wave in Lake Baikal. At each end of each cross-section 

 is indicated the time of high water in lunar hours referred to the centre meridian of 

 the lake; and the numbers below indicate the amplitude in mm. O is the position of 



Penrtschannja Bay. 



parison of the theoretical amplitude with the amplitude derived from the 

 harmonic analysis shows (see Table 72) that the former is nearly twice as 

 large, whereas the phases are almost exactly the same. The difference between 

 the times of high water for M 2 at both ends of the lake is not 6 but 5 lunar 

 hours, which can be considered as a consequence of the bend in the lake. 

 Similar conditions exist for the K t tide; only the amplitudes here are in better 

 agreement with the observed values. The fact that the observed amplitudes
