| Summary: | Sea level anomaly (SLA) data spanning from 1995 – 2015 were used to analyze the
characteristic of eddy current in Northwest Indonesian. An improved winding angle method are
used and were able to detect 2316 anticyclonic eddies (AEs) and 2023 cyclonic eddies (CEs). The
average eddy lifespan is approximately four weeks. Eddy in West Indonesian Ocean have a radius
ranging from 40 – 100 km and high number of mesoscale eddy (radius more than 100 km) detected
in northern area of West Indonesian Ocean (4° N - 10° N). The eddy kinetic energy (EKE)
increases proportionally with their radius, whereas eddy vorticity decreases proportionally with
their increasing radius. The seasonal cycles of eddy circulation in West Indonesian Ocean are
differ for both AEs and CEs, where AEs are dominated during east monsoon season (JJA) and
CEs came with longer periods from November to March, yet for both AEs and CEs they have
similar radius per month. During weak periods of both eddies, their meridional distribution are
differ; CEs tend to be formed in relatively lower latitude, while AEs were concentrated in relatively
higher latitude. |
