1. Boundary Layer Parametrization in Numerical Weather Prediction Models
Abstract : Numerical weather prediction (NWP) and climate models have shown to have a challenge to correctly simulate stable boundary layers and diurnal cycles. This aim of this study is to evaluate, describe and give suggestions for improvements of the descriptions of stable boundary layers in operational NWP models. Two papers are included. READ MORE

2. Data assimilation for numerical weather prediction systems : a 25 year perspective
Abstract : This thesis deals with the assimilation of meteorological observations in numerical weather prediction models. A selection of research and development contributions by the author during 25 years is included and discussed in the light of international development efforts up to the present time. READ MORE

4. Artificial intelligence in weather and climate prediction : Learning atmospheric dynamics
Abstract : Weather and climate prediction is dominated by high dimensionality, interactions on many different spatial and temporal scales and chaotic dynamics. This makes many problems in the field quite complex ones, and also state-of-the-art numerical models are - despite their immense computational costs - not sufficient for many applications. READ MORE

5. On the choice of initial state in numerical weather prediction models
Abstract : This thesis deals with the problem of initializing numerical weather prediction models based on the primitive equation system. The normal mode approach is used i.e. the variables are projected on the eigensolutions of the linearized model equations. READ MORE
