<b>JGR\_Unusual Seasonal Variability of Submesoscale Dynamics in the Arabian Sea</b>

Submesoscale processes in the ocean typically peak in winter, driven by mixed-layer instability and intensified atmospheric forcing, as observed in most global oceans. However, this study reveals the Arabian Sea as a unique exception, exhibiting distinct seasonal variability in submesoscale activity.海洋次中尺度过程（submesoscale processes）通常在冬季达到活动峰值，其驱动机制为混合层不稳定与增强的大气强迫，这一现象在全球多数海域均有观测记录。然而本研究发现阿拉伯海是一个独特的例外，其次中尺度活动呈现出显著的季节变化特征。
