Intraseasonal variability in the Makassar Strait thermocline

Intraseasonal variability in the Makassar Strait thermocline

Intraseasonal variability [ISV] in the Makassar Strait thermocline is examined through the analysis of along-channel flow, regional sea level anomaly and wind fields from January 2004 through November 2006. The dominant variability of 45–90 day in the Makassar Strait along-channel flow is horizontally and vertically coherent and exhibits vertical energy propagation. The majority of the Makassar...

Intraseasonal Kelvin wave in Makassar Strait

[1] Time series observations during 2004–2006 reveal the presence of 60–90 days intraseasonal events that impact the transport and mixing environment within Makassar Strait. The observed velocity and temperature fluctuations within the pycnocline reveal the presence of Kelvin waves including vertical energy propagation, energy equipartition, and nondispersive relationship. Two current meters at...

The Makassar Strait Tsunamigenic Region, Indonesia

The Makassar Strait region has had the highest frequency of historical tsunami events for Indonesia. The strait has a seismic activity due to the convergence of four tectonic plates that produces a complex mixture of structures. The main tsunamigenic features in the Makassar Strait are the Palu-Koro and Pasternoster transform fault zones, which form the boundaries of the Makassar trough. Analys...

Dynamics of Intraseasonal Sea Level and Thermocline Variability in the Equatorial Atlantic during 2002–03

Satellite and in situ observations in the equatorial Atlantic Ocean during 2002–03 show dominant spectral peaks at 40–60 days and secondary peaks at 10–40 days in sea level and thermocline within the intraseasonal period band (10–80 days). A detailed investigation of the dynamics of the intraseasonal variations is carried out using an ocean general circulation model, namely, the Hybrid Coordina...
