摘要: Abstract Fronts are ubiquitous phenomena in oceans, and they play a significant role marine hydrodynamics ecology. During the stratified season of shelf sea, coastal front is usually considered as single front, i.e., tidal mixing front. However, using high resolution (~1 km) Multi-scale Ultra-high Resolution (MUR) analysis sea surface temperature (SST) data, this study observes persistent double fronts along Yellow Sea coast summertime. The comprise well-known offshore nearshore has not been previously reported. climatological (2002–2017) monthly mean result shows that with two SST gradient peaks exceeding ~2 °C/100 km opposite directions basically remain unchanged from June to August, whereas frontal spacing decreases September. Analyses based on two-layer concept model suggest topographic slope could induce pattern fronts. frontogenesis thermal be associated different responses water column depths insolation. movement September related fast cooling intensified wind, important for determining (loose or tight). This new season, indicates significance satellite data. discovery implies influence during ecology environment might underestimated.
