2020 ASP Colloquium - The Science of Subseasonal to Seasonal (S2S) Predictions

No longer accepting applications, the application period has passed.



Coronavirus (COVID-19) information

-April 2, 2020-

The National Center for Atmospheric Research's highest priority is the safety, health, and well-being of our Colloquium attendees.

Due to the COVID-19 pandemic we made the difficult decision to postpone the ASP Colloquium - The Science of Subseasonal to Seasonal (S2S) Predictions to summer of 2021. 

Applications will be reviewed this fall and selected candidates will be notified. There is no need to resubmit an application for 2021. 

We are very sorry for not being able to offer a colloquium this summer and hope to see you soon at NCAR!   

Please see the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) regarding the Coronavirus outbreak (COVID-19) both in the United States and abroad. 


Every year, the Advanced Study Program hosts a summer colloquium designed for graduate students on subjects that represent new or rapidly developing areas of research for which good course material may not yet be available. The colloquium brings together lecturers and graduate students to NCAR and generally includes about 25 student participants, and several lecturers from NCAR and the community at large.


In 2020, the Advanced Study Program is hosting "The Science of Subseasonal to Seasonal (S2S) Predictions."

Organizers: Judith Berner (NCAR) and Aneesh Subramanian (CU Boulder)
Scientific organizing committee:Yaga Richter (NCAR), Elizabeth Barnes (Colorado State University), 
Donata Giglio (CU Boulder),Neena Mani Joseph (IISER Pune, India), Arun Kumar (NOAA/CPC), Kathy Pegion (GMU),Carolyn Reynolds (NRL), Sam Shen (SDSU), Yuhei Takaya (JMA-MRI, Japan), Frederic Vitart (ECMWF),Duane Waliser (JPL/CalTech), and Chidong Zhang (PMEL/NOAA)

This colloquium will be held at the National Center for Atmospheric Research (NCAR) in Boulder, CO, USA. July 6-24 2020

This Summer Colloquium is intended to bring experts from academia and operational centers together with graduate students and early-career scientists to discuss predictions on the subseasonal to seasonal timescale. S2S science bridges the prediction gap between weather and climate and forecasts on this timescale are highly sought after by the energy, water management, agriculture, and other sectors.

This colloquium is intended for advanced graduate students or post-docs whose expertise includes atmospheric and adjacent sciences. It will feature lectures from domestic and international experts on the fundamental processes leading to S2S predictability such as the Madden-Julian Oscillation, sudden stratospheric warmings, and interactions with the land and cryosphere.

Approximately 25 students will be selected to participate in the colloquium. Travel costs (air fare, lodging, ground transportation, etc.) will be covered for all selected participants. However, selected participants must pay a fee to cover workshop refreshments.

Expected Outcome
This colloquium will provide attendees with an integrated conceptual understanding of numerical modeling, initialization strategies, ensemble configuration and applications of S2S-predictions. Attendees will also gain hands-on experience by applying probabilistic verification and process-based S2S diagnostics to numerical simulation output.

Scientific workshop

As part of the colloquium a scientific workshop will take place July 13-17, 2020 as part of which invited speakers will present the latest results and challenges in this fast moving field.
