The GLOBO model contribution to the Stratospheric Nudging And Predictable Surface Impacts (SNAPSI) project produced by the modelling team at the Institute of Atmospheric Sciences and Climate, Bologna, Italy (CNR-ISAC).

The SNAPSI project is a model intercomparison project to study the role of the stratosphere in subseasonal forecasts following stratospheric sudden warmings and the representation of stratosphere-troposphere coupling in subseasonal forecast models.
