On the Seiches of Lake Hamana. (Second paper)

摘要

This paper contains the following results:(1) The undulation of water with period of eleven minutes has been recorded by a tide-guage, installed sometimes at few places in Lake Hamanako. Comparing the observed amplitude of oscillation with our theory we found that they are not in agreement at the northern parts of this lake, near the mouth of Lake Inasahosoeko. He has discussed them as the mouth-effect of Lake Inasahosoeko, northern small part of this lake.(2) The principal cause of the seiches of eleven minutes is due to the Westerly gales blowing after the passage of cycloue, and the period of eleven minutes is difficult to explain by the undulation of water in a bay with narrow mouthes.
