摘要: Abstract The formation mechanisms of the barrier layer (BL) and its seasonal variability in Arabian Sea (AS) are studied using a comprehensive dataset temperature salinity profiles from Argo other archives for AS. Relatively thick BL 20–60 m with large spatial extent is found central-southwestern AS (CSWAS), convergence zone monsoon wind, during peak summer (July–August) southeastern (SEAS) northeastern (NEAS) winter (January–February). Although SEAS has been reported before, observed late new findings this study. thickness (BLT) closely related to processes that occur monsoons. During both seasons, Ekman distribution low-salinity waters surface show dominant influence on observe...
