Recent observations and modeling in the Arabian Sea Laccadive High region

Abstract

Recent observations that include an airborne expendable bathythermograph (AXBT) survey and coincident satellite altimeter measurements together with a high‐resolution numerical simulation indicate that the Laccadive High, an anticyclonic circulating feature that forms off the SW coast of India during the NE monsoon, is comprised of multiple eddies. It is hypothesized that in addition to local and remote seasonal forcing, the Laccadive High region is influenced by an intraseasonal signal that originates in the Bay of Bengal.
