Titli was the cataclysmic storm to afflict Indian coast during 2018. Tropical cyclones may inflate nutrients on the surface layer of the ocean by entrainment and mixing, as a result, the upper oligotrophic and euphotic layers may be recharged with rich nutrients resulting in triggering phytoplankton blooms and significant increase in primary production. The biological response using the chlorophyll concentration from Oceansat-2 OCM and the Net Primary Productivity from MODIS-A to this cyclone and its relation with the cyclone intensity has been studied. Role of physical oceanography parameters has been studied using multiple satellite-derived parameters like SST, TCHP, SLA, Ekman pumping velocity, wind stress and wind vectors and eddies during the passage of cyclone Titli. The results showed an increase in the surface chlorophyll concentration from 0.08 (before) to 0.32 mg m⁻³ (after), whereas NPP enhanced from 457 to 1313 mgC m⁻² day⁻¹ with an SST drop of ~2.58°C (30.25°–27.67°C). The study confirms that the physical parameters are the key components that influence the biological response in addition to the cyclone intensity.

Titli是 2018 年影响印度海岸的灾难性风暴。热带气旋可能通过夹带和混合使海洋表层的营养物质膨胀，因此，上部贫营养和富光层可能会补充丰富的营养物质，从而引发浮游植物大量繁殖和初级生产的显着增加。利用 Oceansat-2 OCM 的叶绿素浓度和 MODIS-A 的净初级生产力对该气旋的生物响应及其与气旋强度的关系进行了研究。已使用多个卫星衍生参数（如 SST、TCHP、SLA、Ekman 泵送速度、风应力和风向量以及旋风Titli通过期间的涡流）研究了物理海洋学参数的作用. 结果显示表面叶绿素浓度从 0.08（之前）增加到 0.32 mg m ^-3（之后），而 NPP 从 457 增加到 1313 mgC m ^-2天^-1，SST 下降约 2.58°C (30.25 °–27.67°C）。研究证实，除了气旋强度之外，物理参数是影响生物反应的关键因素。
