Cotidal Charts f-Plane Solutions Pacific Ocean near Hawaii
2009/3/7
The tidal constituents K1, O1, P1, Q1, M2, S2, N2, K2 derived from sea level records at six sites spanning the Hawaiian Islands show a systematic variation in amplitude and phase from site to site tha...
Eastern Boundary Conditions and Weak Solutions of the Ideal Thermocline Equations
Boundary Conditions Weak Solutions Ideal Thermocline Equations
2009/1/13
It is argued that the ideal fluid thermocline equations have “weak” (i.e., nondifferentiable) solutions that satisfy no mass-flux boundary conditions at the East. This conclusion is based on a local a...
