In the context of the MoU between IRDR and WWRP/WCRP’s SERA Working Group, R. Klein attended and spoke at the workshop on Sub-seasonal to Seasonal (S2S) predictability of monsoons, held on 22 – 24 June 2015 at the National Institute of Meteorological Research Jeju, Republic of Korea.

Presenters – notably a good number of early career scientists – covered monsoon regions from around the world, including South America. The workshop discussed recent advances and current issues covering sub-seasonal to seasonal prediction of monsoons, with an emphasis on lead times of 2 to 4 weeks on:

(a) prediction of the onset and cessation of the monsoon,

(b) prediction of high-impact weather events and dry and wet spells during the monsoon season; (c) use of coupled ocean-atmosphere models for monsoon prediction;

(d) statistical prediction; and

(e) prediction of monsoon impacts at local scale for applications.

Next to this specific framework the workshop explored experiences and opportunities for closer engagement with user communities, and for the co-design of research. It was in this segment of the programme that future closer collaboration was seen as most promising, just as for the other two Thorpex legacy projects.
