Abstract

TOPEX/Po seidon altimeter data from October 1992 to June 2002 and Levitus(1998) are used to calculate the energy flux of M₂ internal tides in the Pacific Ocean,basing on inter naltides dynamical equation.M₂ internal tides,that yield energy transmission,are extracted from temporarily coherent internal tide signals in the altimeter data.The method is testified by the field measurements of ADCP current velocities in the South China Sea.The results show that satellite-derived M₂ tide components agree with the field data very well.Computation results indicate that the total energy flux of M₂ internal tides along the margin of Pacific Ocean is about 58.4 GW,in which 30.2 GW is from the North Pacific and 28.2 GW is from the South Pacific.However,the total energy flux of M₂ internal tides from the margin of East Pacific is 17.8 GW and 40.6 GW from the margin of the West Pacific.(160°W is taken as the boundary of the East Pacific Ocean and West Pacific Ocean)
