摘要： Strong sea surface temperature fronts in open seas are known to affect the atmosphere. Shelf-sea fronts in winter have comparable strengths, yet their impacts on winds have not been studied. In January of 2012, a persistent, narrow band of cloud stretching 600–1,000 km was observed along the front of East China Sea (ECS). Numerical and analytical models show that the cloud was formed atop a recirculating cell induced by the front and, more generally, that β-plumes of low and high pressures emanate and spread far from fronts. Consistent with the theory, observations show that in ECS at inter-annual time scales, strong fronts co-vary with on-shelf convergent wind, strong northeasterly monsoon, and alongshelf alignment of clouds with low clouds near the coast and higher clouds offshore. Our results suggest that shelf-sea fronts are potentially an important dynamic determinant of climate variability of East Asia. 其他題名： Clim Dyn 出版者： Berlin/Heidelberg: Springer Berlin Heidelberg 出版日期： 2015-10-01 出處： Climate dynamics, 2015-10, Vol.45 (7-8), p.2047-2068 資源來源： Agricultural & Environmental Science Collection 版權： Springer-Verlag Berlin Heidelberg 2015 識別號： ISSN: 0930-7575 識別號： EISSN: 1432-0894 識別號： DOI: 10.1007/s00382-014-2455-3
