A team of scientists comprising Odisha-born Bishnupriya Sahoo and Jiya Albert and Prasad K Bhaskaran from IIT Kharagpur, with support from the Department of Science & Technology, Government of India under the Climate Change Programme (CCP), has devised a promising technique for early detection of development or strengthening of tropical cyclones in the atmospheric column prior to satellite detection over the Bay of Bengal (BoB) basin. A researcher in Physical Oceanography, Sahoo currently works as a Research Scientist at the Yantai Institute of Coastal Zone Research, China. She pursued her PhD at IIT Kharagpur in Physical Oceanography from 2014 to 2018. Sahoo had pursued her MSc in Mathematics at NIT, Rourkela and BSc and +2 Science at Rama Devi Women’s Autonomous College, Bhubaneswar. Her schooling took place at the Basipitha Government High School, Mayurbhanj. Early detection of tropical cyclones has wide socioeconomic implications. So far, remote sensing techniques have detected them the earliest. However, this detection was possible only after system developed as a well-marked low-pressure system over the warm ocean surface. A larger time gap between the detection and the impact of the cyclone could help preparation activities. Prior to the formation of cyclonic system over the warm oceanic environment, the initial atmospheric instability mechanism as well as the vortex development is triggered at higher atmospheric levels. These cyclonic eddies are prominent features in vertical atmospheric column encompassing disturbance environment with a potential to induce and develop into a well-marked cyclonic depression over warm ocean surface. They could be used for detection of prediction of cyclones. The method developed by scientists would identify initial traces of pre-cyclonic eddy vortices in atmospheric column and track its Spatio-temporal evolution. They used coarser grid resolution of 27 km for identification and finer resolution of 9 km to evaluate characteristics of eddy vortices. The study was conducted with cases of four post-monsoon severe cyclones. Phailin (2013), Vardah (2013), Gaja (2018), Madi (2013) and two pre-monsoon cyclones Mora (2017) and Aila (2009) that developed over North Indian Ocean. The team observed that method could bring about genesis of prediction with a minimum of four days (~ 90 h) lead time for cyclones developed during pre-and post-monsoon seasons. Initiation mechanisms of genesis of tropical cyclones occurs at upper atmospheric levels and are also detected at higher lead time for pre-monsoon cases, unlike post-monsoon cases. The study made a comprehensive investigation on behavior of eddies in an atmospheric column for non-developing cases and compared these findings with developing cases. The technique was found to have potential for an early detection of tropical cyclogenesis in atmospheric column prior to satellite detection over ocean surface.
