摘要: Abstract Tidal observations and a numerical model locate the resonant period of Bay Fundy at value lying between 12.5 12.7 h, close to that tidal component N 2 (12.66 h), which is created by monthly variations in distance Moon. The nodal modulations major M (12.42 alter its amplitude ±4% over span 19 years, do influence frictional characteristics system turn affect period. A large shifts this closer : reflected are synchronous with those . In contrast S (12 away from resonance, reduced an increased vice versa.
