Events and Highlights 2017-2018

Vineet wins the Best Poster Award at the IMS Annual Monsoon Workshop, Pune, Mar 2018

Congrats to Vineet Kumar – the cyclone guy – from our Climate Lab team for the best poster award at the IMS Monsoon Workshop. The study looked into the ocean-atmosphere conditions which determined the track and sudden intensification of cyclone Ockhi.

IndOOS Review at Jakarta, Indonesia, Mar 2018

The decadal review of the Indian Ocean Observation System (IndOOS) was held at Jakarta, Indonesia, during 18-23 March 2018. The review evaluated the climate variability and changes in the Indian Ocean, and proposed a revision of the observation network to address emerging scientific issues. The review was held along with the IIOE-2/SIBER/IOGOOS meetings and the 14th Annual Meeting of the Indian Ocean Region Panel, co-chaired by Roxy Mathew Koll.

IPCC SROCC Second Lead Author Meeting at Quito, Ecuador, Feb 2018

The IPCC authors met at Quito in Ecuador to develop the Special Report on Ocean and Cryosphere in a Changing Climate (SROCC). Roxy Mathew Koll is dealing with the chapter on extremes and abrupt changes in the ocean, and managing the risks. The meeting in Quito, the second of four lead author meetings for the report, will lead to the preparation of the First Order Draft which will be circulated for expert review in May 2018. The report will be finalized in September 2019.

Co-Chair of the CLIVAR Indian Ocean Region Panel

Roxy Mathew Koll takes charge as the Co-Chair of the CLIVAR Indian Ocean Region Panel for the period 2018-2021. The CLIVAR Panel provides scientific and technical oversight for implementation of the sustained ocean observing system for the Indian Ocean and coordinates research on the role of the Indian Ocean on the climate system. Roxy will serve the CLIVAR panel along with Co-Chair Prof. Lisa Beal of Rosenstiel School of Marine and Atmospheric Science, University of Miami.

IITM Silver Jubilee Award

Roxy Mathew Koll and Co-Authors Aditi Modi, Swapna Panickal and Vinu Valsala got the Silver Jubilee Award for the Best Research Paper in 2016, for the paper “A reduction in marine primary productivity driven by rapid warming over the tropical Indian Ocean”, published in Geophysical Research Letters.

Nature Climate Change features our study on extreme rains as a Research Highlight

Graham Simpkins, Nature Climate Change Editor writes – 

In late August and early September, 30 million people were affected by widespread flooding in India due to extreme rainfall. Such events have become increasingly common in recent decades, but coincide somewhat counter-intuitively with a long-term reduction in mean precipitation and a corresponding decline in the frequency of rain-bearing depressions.

Roxy Mathew Koll from the Indian Institute of Tropical Meteorology and colleagues quantify changes in extreme rainfall across the Indian sub-continent, and further diagnose the mechanisms responsible for such enhanced hydroclimatic variability in the region… [Read More] [pdf]

A threefold rise in widespread extreme rains over India

Widespread extreme rain events across central India have tripled since 1950, reports a study led by Dr. Roxy Mathew Koll and his team at the Indian Institute of Tropical Meteorology (IITM), and published in Nature Communications. These severe weather events result in large-scale floods and catastrophic loss for life and property across central and northern India – Gujarat, Maharashtra, Madhya Pradesh, Chhattisgarh, Telangana, Odisha, Jharkhand, Assam and parts of Western Ghats – Goa, north Karnataka and South Kerala. The study finds that the rise in extreme rains are due to increasing fluctuations (variability) in the monsoon winds (westerlies), in a changing climate [Read more].

The study on extreme events, due to its impact on the large-scale floods and catastrophic loss for life and property across India, received huge attention in the media, with national television channels airing it at prime-time, and many newspapers and magazines covering it as front-page headlines [See our media section].

Lead Author of the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC)

Roxy Mathew Koll IPCC interview in Deccan Chronicle on ocean sciences and droughtRoxy Mathew Koll has been selected as a Lead Author of the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). The Intergovernmental Panel on Climate Change (IPCC) provide regular assessments for policymakers of the scientific, technical and socio-economic aspects relating to climate change. In the SROCC, Roxy will be dealing with a chapter on extremes and abrupt changes in the ocean, and managing the risks.

Panini wins the Best Poster Award at the OSICON ’17 Conference, Thiruvananthapuram, Aug 2017

Best Poster Award at OSICON 17 for Panini DasguptaPanini Das Gupta won the Best Poster Award for his research on “Interannual Variability and changes in the initiation and lifecycle of Madden Julian Oscillation”, at the OSICON 17 Conference in Thiruvananthapuram, September 2017.

The IndOOS Review, First Meeting at Perth, Australia, Feb 2017
IOGOOS/IOP/SIBER/IRF/IIOE-2 Meeting and Bio-Argo WorkshopThe Indian Ocean Observing System (IndOOS) data is used in addressing societal and economic needs, in weather and seasonal climate forecasting and in the production of routine ocean-maps, re-analyses and predictions. Along with US, Japan, Australia and other countries, India is a major stakeholder in implementing the Indian Ocean observing systems. The major challenge for IndOOS at this time is to find and focus the resources of individual nations to achieve a coherent completion of the IndOOS plan, in particular to sustain the observing system and to build capacity to enable participating agencies to assimilate this data into operational forecasting models. In order to achieve this, an IndOOS Review meeting was hosted by UNESCO – Intergovernmental Oceanographic Commission (IOC) at Perth, Australia in Feb 2017. From IITM, Roxy Mathew Koll and R. R. Rao contributed in preparing a plan and white paper report for the IndOOS Review. [CLIVAR Indian Ocean Panel].
