Sea Surface Energy Fluxes' Response to the Quasi‐Biweekly Oscillation: A Case Study in the South China Sea

Abstract The South China Sea (SCS) owns the world's strongest quasi‐biweekly oscillation (QBWO) in boreal summer, but mechanism is still unclear. This case study summarizes two modes of QBWO over summer SCS 2019 by using empirical orthogonal function on 10–20‐day bandpass‐filtered outgoing longwave radiation fields. maximum positive irradiance anomalies for are 90 W m −2 . upward solar and downward own about 4%–8% magnitude, surface shows a weak response. turbulent heat fluxes' responses to display different spatial patterns compared fluxes. Their changes mainly ascribed wind Mode1 air‐sea thermal contrast Mode2. We also discuss cause impact sea fluxes QBWO.
