The final session on the Indian Ocean Observation System (IndOOS) Decadal Review was held at Port Elizabeth, South Africa, during 11-15 March 2019.

Roxy Mathew Koll and Lisa Beal, co-chairs of the Indian Ocean Region Panel (IORP) introduced the scientific and societal drivers and more importantly the core findings and actionable recommendations for a revised IndOOS. The review was held along with the IIOE-2/SIBER/IOGOOS meetings and the 15th Annual Meeting of the IOPR.

IPCC SROCC Fourth Lead Author Meeting at Kazan, Russia, Mar 2019

The IPCC authors met at Kazan in Russia to prepare the Final Draft of 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. 

Review on the impacts of anthropogenic climate change on the monsoon

We have recently published two review papers on the impacts of anthropogenic climate change on the Indian summer monsoon.

1. Indian summer monsoon: Extreme events, historical changes, and role of anthropogenic forcings by D. Singh, S. Ghosh, M. K. Roxy and S. McDermid in WIREs Clim Change, 2019, 10:e571, doi:10.1002/wcc.571 [pdf].

2. Impacts of Climate Change on the Indian Summer Monsoon by M. K. Roxy and S. T. Chaithra in Climate Change and Water Resources in India, edited by Vimal Mishra, and J. R. Bhatt, Ministry of Environment Forest and Climate Change, 2019, 21-37, ISBN: 978-81-933131-6-9 [pdf].

Interannual variability and trends of the Indian summer monsoon, showing the drought and flood years, along with El Nino and La Nina conditionsThe figure above shows the percentage departure of summer monsoon rainfall over central India (76-86°E, 19-26°N) during 1901-2018. Wet years (above 10% departure) are marked in dark blue color and drought years (below -10% departure) are marked in red color. El Niño and La Niña conditions for the summer season are marked using red and blue dots.

Science communication @ school

Vineet and team visits schoolVineet, Dr. Milind Mujumdar and team visited the Narayan Maharaj Madhyamik School at Narayanpur and introduced the students to the basics of weather and climate. The team from IITM gifted a digital thermometer to the school.

The digital thermometer has the facility to record indoor and outdoor daily maximum minimum temperature and relative humidity. The students will daily readings and send those readings to IITM. This will be a useful record since the location doesn’t have any weather stations nearby. The team is also planning to install a rain gauge at the school location before this monsoon.

A month’s rain in three days – Kerala Floods, BBC Radio

Interview with Roland Pease of BBC Radio, Science in Action Series. Starts at 0:53.

Roxy Koll, Climate Scientist at IITM, Pune and NRC Visiting Scientist at PMEL/NOAA, is interviewed on BBC World Service “Science In Action” discussing the widespread flooding in Kerala. Dr. Koll’s research has shown that monsoons have been getting weaker, delivering less rain on average, while extreme floods, have paradoxically become much more common.
