Major Upgrade to Version 1.1.0 of the experimental Canadian Arctic Prediction System (CAPS) at the Canadian Meteorological Centre
On Tuesday June 28 2018, starting with the 1200 UTC run, the Meteorological Service of Canada's Canadian Meteorological Centre (CMC) upgraded the experimental Canadian Arctic Prediction System (CAPS) to version 1.1.0.
The changes included in this upgrade are summarized as follows:
- Introduction of two-way coupling with an ice-ocean model. In the CAPS-1.1.0 forecast system, surface conditions evolve through coupling with an Ice-ocean model. This Ice-ocean model is also used in RIOPS.
