Understanding the Mechanism of Currents through the Malacca Strait Study Case 2020 – 2022 : Mean state, Seasonal and Monthly Variation

Abstract The Malacca Strait is the importance waters for international shipping routes and more 200 cases of ship collisions in period 1970-2015 this strait. That related to some a shallow depth with many small islands strong current which making strait have highest risk certain seasons. CMEMS data used understanding mechanism current, illustrate pattern tranport volume. research uses descriptive statistical methods variability current. analysis patterns water level shows that during monsoon winds active, always moves Andaman Sea, we called southeast system. Northeast (NE) Southwest (SW) wind strongly influence formation system, causes varition sea hight eastern western Strait. During NE season, masses South China Sea are push away into Karimata Strait, causing part be higher than will increase speed. On other hand, SW from pushed decrease speed weaken. Numbers eddies phenomenon were found at each season. anticyclonic occurred almost every season centered 3° - 5° N, 97° 100° E. Meanwhile appear around northern Sumatra 4° 5°N, 99° 101°E Monsoon also existed second transition
