The previous concise review of (mostly) observational studies reveals that the present knowledge of the Zhoushan upwelling is unsatisfactory and has focused on seasonal variations. In this study, a sea surface temperature (SST) gradient-based upwelling detection algorithm was used. The Level 3 daily and hourly SST data from the geostationary satellite Himawari-8 were used to explore statistical features, seasonal variations, and short-term variations of the Zhoushan upwelling. Despite the duration period being like in previous studies, there is a new finding that the location of the upwelling center has a significant monthly migration. The statistical results show that the potential upwelling spots are clustered in the location with large topographic gradients and can be divided into four aggregation areas: between Gouqi Island and Lvhua Island, off Shengsi Island, around the Zhongjieshan Islands, and off the Taohua-Liuheng Islands. The core area of the Zhoushan upwelling is located at 122\u00b0E\u2013123\u00b0E, 29.5\u00b0N\u201331.15\u00b0N with an irregular ellipse extending from southwest to northeast. The continuous cloud-free satellite images display that the lifecycle of the short-term variations was about 24 h and included two stages: intensification and decay. Meanwhile, the surface upwelling center has onshore\u2013offshore movement under the advective transport of local tidal currents. A preliminary discussion suggests that the quasi-24 h periodic variations may be caused by the competing effect between tidal mixing and the stratification in the water column.<\/jats:p>","DOI":"10.3390\/rs14143261","type":"journal-article","created":{"date-parts":[[2022,7,6]],"date-time":"2022-07-06T21:15:52Z","timestamp":1657142152000},"page":"3261","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Surface Upwelling off the Zhoushan Islands, East China Sea, from Himawari-8 AHI Data"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8931-4975","authenticated-orcid":false,"given":"Wenbin","family":"Yin","sequence":"first","affiliation":[{"name":"College of Marine Science and Technology, Zhejiang Ocean University, Zhoushan 316022, China"}]},{"given":"Youzhi","family":"Ma","sequence":"additional","affiliation":[{"name":"College of Marine Science and Technology, Zhejiang Ocean University, Zhoushan 316022, China"}]},{"given":"Dian","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Marine Science and Technology, Zhejiang Ocean University, Zhoushan 316022, China"}]},{"given":"Shuangyan","family":"He","sequence":"additional","affiliation":[{"name":"Ocean College, Zhejiang University, Zhoushan 316021, China"}]},{"given":"Daji","family":"Huang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Tropical Marine Ecosystem and Bioresources, Fourth Institute of Oceanography, Ministry of Natural Resources, Beihai 536000, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"L\u00fc, X., Qiao, F., Xia, C., Zhu, J., and Yuan, Y.
