摘要：In the past, data assimilation has been performed in the context of perfect model. The role of model error has become more prominent in the last years. This model error comes from many sources including: sub-grid parameterisations, numerical discretisation, lack of understanding of some physical process, and the so-called representation error arising from the mismatch in resolution between observations and models.Since its origin is so varied, model error can come in all types and flavours. We have been exploring the time structure in model error and the consequences of its misrepresentation.
