Pune, 3 June 2024
An International Workshop on Stratosphere-Troposphere Interactions and Prediction of Monsoon weather EXtremes (STIPMEX) is being organised at Indian Institute of Tropical Meteorology (IITM), Pune during 2-7 June 2024.
A formal inauguration program of the ‘STIPMEX’ workshop was conducted on Monday, 3rd June 2024 in the virtual presence of Dr. M. Ravichandran, Secretary, Ministry of Earth Science.
On this occasion Dr. R. Krishnan, Director, IITM, Guests of Honours Dr. Rolf Müller, Director, Atmospheric Processes And their Role in Climate (APARC), Dr. Estelle De Coning, Head, WMO World Weather Research Programme (WWRP), Marc von Hobe, Member APARC SSG were present.
Around 300 participants from India and 30 different countries of Asian, European, American, and African continents are attending the International workshop. During the Inauguration program, an online Compendium of Abstract also released.
Dr R Krishnan, Director, IITM, extended a warm welcome to all the distinguished delegates and to the conference participants from 30 different countries.He stated the importance of the conference as it is integrating the scientific community of weather and climate. Dr. Krishnan also focused on new initiatives and insights for future pathways of forecasting extreme events.
Dr M Ravichandran, Secretary MoES, Govt of India, in his inaugural address (virtual) as a Chief Guest, highlighted the advancements in technology & techniques offering promising solutions in forecasting extreme weather events & also apprised the event’s focus on stratospheric chemistry & monsoon extremes. He emphasized on the recent changes/trends in stratosphere-troposphere coupling process, Asian summer monsoon and stratospheric chemistry and also highlighted challenges in forecasting extreme weather and the need of accurate and timely prediction of extreme weather events. Finally, he conveyed his best wishes for success of the conference.
Guest of Honor Marc von Hobe, Dr. Estelle De Coning appretiated & thanked IITM and MOES for organizing a landmark event like STIPMEX in India. Dr. Suvarna Fadnavis presented the Vote of Thanks.

about STIPMEX:
Over the past few decades Asia including the Indian region has been experiencing extreme weather systems causing unprecedented damage to public property and loss of life such as the unprecedented heavy rainfalls in Kerala during Aug 2018 and 2019, extremely heavy rainfall over Tamil Nadu in December 2023 etc. The current major concern of our society has become to find ways to manage the enhanced frequency of extreme events affecting human lives and property. The NWP models have shown significant improvement in skill over past few decades but predicting a localized extreme event with longer lead, still remains an open question.
Recent research reveals that the stratospheric processes are important for improving the predictability of the troposphere including monsoon. However, the complexities of the underlying mechanisms of stratosphere-troposphere coupling processes are difficult to incorporate in the model. Stratospheric chemistry controls the magnitude and distribution of many important forcing agents in the troposphere. Influence of stratospheric variability such as sudden stratospheric warmings and their subsequent impact on the troposphere or the quasi-biennial oscillation and its associated teleconnections show an association on Indian summer monsoon rainfall variability. The impact of stratospheric aerosols, and, water vapor are also important for the Indian summer monsoon due to their contributions to radiative forcing. The deliberation in the STIPMEX workshop by the experts from the stratospheric and tropospheric community will bridge the gap of inclusion of stratospheric and tropospheric processes in the model for better prediction of monsoon extremes.
To emphasize this aspect, the workshop will focus and deliberate on all aspects of extreme weather prediction and the latest state-of-the-art model from the leading operational centres of the world such as ECMWF, Germany, NCEP, USA, JMA, Japan, etc. The researchers/experts on the chemistry of stratosphere-troposphere modeling, and observations e.g. aircraft, Lidar, and Radars measurements in the high altitude regions over the monsoon region from the USA, parts of Europe, Japan, and India will discuss the improvement of the model and predictions. The deliberation will bring out the gaps in the current prediction systems and also provide the much-needed pathways for addressing the issue of the prediction of extremes in coming years. The understanding of stratospheric and tropospheric processes will throw insights which may further be helpful in making the NWP models more realistic prototype of the real atmosphere and may help in improving its prediction skill.
The reason for conducting the International workshop on stratosphere-troposphere interactions and Prediction of Monsoon weather Extremes was to make the most of the expertise from two communities (1) stratosphere-troposphere interactions and (2) Prediction of Monsoon weather Extremes attending the STIPMEX workshop and discuss the way forward for the improvement of predictions of weather extremes.
