  abstract = {{T}he regional {INDESO} model configured in the {I}ndonesian seas from 2008 to 2016 is used to study the mechanisms responsible for the variability of the currents in the {S}ulawesi {S}ea of the {I}ndonesian seas. {T}he model simulation compares reasonably with the seasonal to interannual variability of the moored current meter observations in the upper 350m or so of the {M}aluku {C}hannel during 2015 and 2016. {T}he interannual variability of the currents in the eastern {S}ulawesi {S}ea in the model is found to be associated with both the {P}acific and {I}ndian {O}cean remote forcing. {L}ag correlation analysis and a theoretical linear wave model simulation suggest that both the equatorial {K}elvin waves from the {I}ndian {O}cean and the coastally trapped {K}elvin waves from the western {P}acific along the {P}hilippine coast can propagate through the {I}ndonesian seas and arrive at the {M}aluku {C}hannel. {I}n particular, from mid-2015 to 2016 the {I}ndian {O}cean {K}elvin waves are found to significantly impact the sea level anomaly variability in the {M}aluku {C}hannel. {T}he results indicate the importance of {I}ndo-{P}acific planetary waves to the interannual variability of the currents in the {S}ulawesi {S}ea at the entrance of the {I}ndonesian seas. {P}lain {L}anguage {S}ummary {T}he {I}ndonesian seas provide a tropical connection for the climate systems over the tropical {P}acific and {I}ndian {O}ceans, the dynamics of which are not clear so far. {T}his study uses a high-resolution computer model to simulate the currents measured by an acoustic current meter attached to a deep ocean mooring in the {M}aluku {C}hannel of the northeastern {I}ndonesian seas. {B}ased on the successful simulation, the dynamics of the interannual variations of the circulation in the {M}aluku {C}hannel are studied using the model and a simplified theoretical linear model. {T}he interannual currents and sea level variability in the {M}aluku {C}hannel are found to be affected by both the {I}ndian {O}cean {K}elvin waves and the {P}hilippine coastal {K}elvin waves. {I}t is found that the {I}ndian {O}cean {K}elvin waves dominate the sea level variability in the {M}aluku {C}hannel from mid-2015 to 2016. {I}n early 2015, the sea level variability in the {M}aluku {C}hannel is dominated by the coastal {K}elvin waves from the east {P}hilippine coasts. {T}he results are important for the understanding of the circulation at the entrance of the {I}ndonesian seas and of the {I}ndo-{P}acific interactions through the propagation of the planetary waves.},
