摘要

地下层温度反演（SLTI）是孟加拉湾冬季发生的一个突出物理过程。BoB在冬季（季风过后）也会出现强烈的气旋。锡德是2007年11月11日至15日发生在BoB的5级气旋。本研究强调了SLTI对SST增温的影响。本文利用观测和建模来介绍SLTI在气旋后表层变暖中的作用。在没有SLTI的情况下，气旋会导致表面冷却。然而，在具有SLTI的表层的情况下，<；在前海湾附近观察到0.5°C的SLTI现象。模型结果和观测结果表明了表层的夹带和变暖的作用。

Role of subsurface layer temperature inversion in cyclone induced warming in the northern Bay of Bengal

Subsurface Layer Temperature Inversion (SLTI) is a prominent physical process occurring in the Bay of Bengal (BoB) during winter. BoB also witnesses intense cyclones during winter (post-monsoon). Sidr is a category-5 cyclone that occurred in the BoB during 11–15 November 2007. The present study emphasises bringing out the effect of SLTI on SST warming. This paper uses observations and modelling to present SLTI's role in surface layer post-cyclone warming. In the absence of SLTI, the cyclone induces surface cooling. However, in the case of a surface layer with SLTI, instead of cooling, sea surface warming of < 0.5 °C is observed near the head bay, where SLTI is prominent. Model results and observations suggest the role of entrainment and warming of the surface layer.

期刊介绍： Dynamics of Atmospheres and Oceans is an international journal for research related to the dynamical and physical processes governing atmospheres, oceans and climate. Authors are invited to submit articles, short contributions or scholarly reviews in the following areas: •Dynamic meteorology •Physical oceanography •Geophysical fluid dynamics •Climate variability and climate change •Atmosphere-ocean-biosphere-cryosphere interactions •Prediction and predictability •Scale interactions Papers of theoretical, computational, experimental and observational investigations are invited, particularly those that explore the fundamental nature - or bring together the interdisciplinary and multidisciplinary aspects - of dynamical and physical processes at all scales. Papers that explore air-sea interactions and the coupling between atmospheres, oceans, and other components of the climate system are particularly welcome.
