Asymmetric Cloud‐Shortwave Radiation‐Sea Surface Temperature Feedback of Ningaloo Niño/Niña

Research on the Ningaloo Coast reveals an asymmetric cloud-shortwave radiation-sea surface temperature (SST) feedback mechanism, where positive SST anomalies trigger a negative feedback due to increased high cloud cover from deep convection, while negative SST anomalies induce a positive feedback linked to low cloud cover under subtropical high influence. This asymmetry arises because the region's relatively high SSTs are near the convective threshold. The study analyzed observational and reanalysis data to uncover this dynamic, shedding light on how cloud-SST interactions differ in eastern boundary regions.
