    摘要:

    本文研究了2017年春季孟加拉湾小型暖池对热带气旋Maarutha(4月14-17日)以及热带气旋Mora(5月27-30日)的影响.利用卫星遥感和现场观测数据分析发现,尽管春季孟加拉湾热带气旋确实能引起海洋上层冷却效应,但是其冷却强度受到暖池强度的影响.本文进一步对比孟加拉湾小型暖池对两个热带气旋的响应情况,发现当春季小型暖池的温度大于31℃(热带气旋Mora期间),暖池效应能有效抑制海洋上层混合层的加深,降低热带气旋引起的潜热通量损失带来的冷却效应,并在一定程度上加强了热带气旋.

    Abstract:

    Two tropical cyclones (TCs) during spring 2017 have been selected as case studies to examine the effect of spring mini-warm pool (MWP) on TCs in the Bay of Bengal (BoB).The TC Maarutha existed over the BoB from 14th to 17th April of 2017,while TC Mora existed from 27th to 30th May of 2017.Existing datasets have been utilized to analyze major factors which influence TC activity in the region.It is identified that the TC-induced sea surface temperature (SST) cooling is evident during spring,but SST is relatively high just before the landfall of the TC Mora in the BoB.This observed warmer conditions are primarily due to the existence of spring MWP in the BoB.When the spring MWP is stronger (SST> 31℃),TC Mora induced mixing does not have any major influence on removing of the TC energy.In addition,the study reveals that the spring MWP suppresses the TC-induced negative effect by deepening the mixed-layer,decreasing cyclone heat potential and latent heat flux during spring in the BoB.
