Jonas Spaeth

Scientist – ocean and sea ice variability and predictability
Research, Earth System Predictability, Extended Range

Summary:
Jonas is a research scientist in the sub-seasonal to seasonal prediction team, working within the ACCIBERG project. He investigates the potential benefits of stochastically perturbed parametrization (SPP) schemes for sea ice and is broadly interested in how large-scale teleconnections influence forecast uncertainty, reliability and skill across the climate system.
Professional interests:
  • sub-seasonal to seasonal predictability
  • ensemble spread and reliability
  • teleconnections with the stratosphere, sea ice and ocean
  • scientific coding and statistical methods
