The Tropical Atmosphere Ocean (TAO) and Triangle Trans-Ocean Buoy Network (TRITON) buoys deployed in the tropical Pacific play a significant role in monitoring tropical Pacific conditions such as El-Niño/La-Niña in real-time. Earlier studies have illustrated the importance as well as irrelevance of moored buoy observations towards the prediction of sea surface temperature in the tropical Pacific Ocean. With the advent of Argo floats, have these moored buoy observations become redundant? In the present study, we address this question in the context of Indian summer monsoon rainfall (ISMR) prediction. The extreme monsoon year of 2018 was selected to test the above hypothesis. Without moored buoy observations being assimilated, the oceanic initial conditions and the seasonal forecasts had large oceanic temperature errors and forecasted a normal monsoon instead of a below-normal monsoon during 2018. Therefore, moored buoy observations are essential and should be assimilated to get realistic Pacific sea surface temperature (SST) and accurate ISMR predictions.

部署在热带太平洋中的热带大气海洋（TAO）和三角跨海浮标网络（TRITON）浮标在实时监测El-Niño/La-Niña等热带太平洋状况方面发挥着重要作用。较早的研究表明，系泊浮标观测对预测热带太平洋海表温度的重要性和不相关性。随着Argo浮标的出现，这些系泊浮标的观测是否变得多余了？在本研究中，我们在印度夏季季风降水（ISMR）预测的背景下解决了这个问题。选择2018年极端季风年来检验上述假设。没有被系泊的浮标观测所吸收，
