Description:

It has been known for decades that advection of a cloud ‐topped marine boundary layer (CTBL) over warmer sea surface causes the strati ﬁcation (or decoupling) of the CTBL via the entrainment feedback, a mechanism commonly known as “deepening ‐warming ”decoupling that is typical in subtropics. This study focuses on the opposite direction of advection, that is, low ‐level warm air advection (LLWAA), and its impacts on the decoupling degree of a CTBL. Our hypothesis is that LLWAA stabilizes a CTBL, causing a decoupling of the CTBL. It is tested for three LLWAA episodes observed during the Measurements of Aerosols, Radiation, and CloUds over the Southern Ocean
