The merged TOPEX/POSEIDON and ERS‐1/2 altimeter data from 1993 through 2001 and
the Spectral Element Ocean Model (SEOM) have been used to investigate Indian Ocean
Kelvin waves (IOKWs), specifically their propagation and energy intrusion into Lombok
Strait. The altimeter data show the frequent occurrence of IOKWs in either April/May or
November/December for the years of 1993–2001 (except 1994) with intraseasonal wave
periods (phase speeds) ranging from 35 (1.5) to 90 days (2.9 ms− 1). From the altimeter …

The merged TOPEX/POSEIDON (T/P) and ERS-1/2 altimeter data during 10/14/1993–
2/12/2002 have been used to study Indian Ocean Kelvin waves propagation along the south
coast of Jawa, Bali, Lombok, and the Lesser Sunda Islands. The results show that the
occurrence of semiannual Indian Ocean Kelvin waves either in April/May or
November/December for all the year of 1993-2001 (except in 1994) with the intraseasonal
period and phase speed ranging from 35 to 90-day and 1.54 to 2.9 m/s, respectively.
