  2. 1. Boundary Layer Parametrization in Numerical Weather Prediction Models

    Author : Jacob Svensson; Gunilla Svensson; Michael Tjernström; Patrick Samuelsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Boundary-Layer Meteorology; Numerical Weather Prediction; Turbulence parametrization; COAMPS; IFS; meteorologi; Meteorology;

    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

  4. 2. Data assimilation for numerical weather prediction systems : a 25 year perspective

    Author : Nils Gustafsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; meteorologi; Meteorology;

    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

  5. 3. Ensemble Kalman filters in mesoscale limited-area numerical weather prediction

    Author : Andreas Grantinger; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meteorology; Meteorologi;

    Abstract : .... READ MORE

  6. 4. Artificial intelligence in weather and climate prediction : Learning atmospheric dynamics

    Author : Sebastian Scher; Gabriele Messori; Roberto Buizza; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    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

  7. 5. On the choice of initial state in numerical weather prediction models

    Author : Lennart Thaning; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    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
