Description

Speaker: Iuliia Polkova (Univ. Hambourg)

Presentation covers initialization of climate predictions in general.
I will try not to bore audience with the analyses of skills or
mechanisms for predictability, though the presentation relies on such in already published papers. Instead…  it would be interesting to have an interactive conversation on initialization, even though it might not be everyone’s topic, and to talk about challenges of this field of research and maybe identify interesting directions also with input from the audience. As a teaser for discussion, I have collected some ideas behind different initialization and assimilation methods for decadal predictions and my speculations why they fulfilled or not fulfilled the expectations of their developers.  I also mention whether uninitialized predictions can replace initialized predictions and speculate about what we can try to learn from simpler climate models in terms of initialization and data assimilation. I suppose the presentation would be of interest for prediction system developers but hopefully not only. If someone wants to know how observations enter prediction systems and implications of this for the quality of predictions, they should drop by. Hopefully, we can have interesting discussions.
