North Pacific internal tides from the Aleutian Ridge: Altimeter observations and modeling

摘要

Internal tides radiating into the North Pacific from the Aleutian Ridge near Amukta Pass are examined using 7 years of Topex/Poseidon altimeter data. The observations show coherent southward phase propagation at the M_2 frequency over a distance ofat least 1100 km into the central Pacific. Barotropic and baroclinic models are applied to study this internal tidal signal.
