  1. 1. Data-driven analysis of water and nutrient flows: Case of the Sava River Catchment and comparison with other regions

    Författare :Lea Levi; Vladimir Cvetkovic; Georgia Destouni; Roko Andričević; Ronny Berndtsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; River catchment; Transboundary; Hydro-climatic change; Total nitrogen; Total phosphorus; CMIP5; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : A growing human population and demands for food, freshwater and energy are causing extensive changes in the water and biogeochemical cycles of river catchments around the world. Addressing and investigating such changes is particularly important for transboundary river catchments, where they impose additional risk to a region’s stability. LÄS MER

  3. 2. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models

    Författare :Thanh Le; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar forcing; volcanic forcing; greenhouse gases radiative forcing; Granger causality; near-surface air temperature; ENSO; IOD; CMIP5; North Atlantic;

    Sammanfattning : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. LÄS MER

  4. 3. Observed and simulated changes in extreme precipitation and cold surges in China: 1961–2005

    Författare :Tinghai Ou; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate extremes; Precipitation; Cold surge; Siberian High; CMIP5; reanalysis; atmospheric circulation;

    Sammanfattning : In the present work, precipitation and temperature related climate extremes are examined, with a focus on Mainland China. The objectives of this study are a) to identify targeted climate extremes and their changes during the last decades, and b) to examine the ability of current global climate models to reproduce identified patterns of change.

  5. 4. The Representation of Atmospheric Boundary Layer Processes in Global Climate Models

    Författare :Jenny Lindvall; Gunilla Svensson; Rodrigo Caballero; Andrew R. Brown; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; The atmospheric boundary layer; Global climate models; Diurnal cycle; Flux towers; Diurnal temperature range; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The atmospheric boundary layer is the lowest part of the atmosphere, which is in direct contact with the surface. It is here, in this turbulent layer, that the exchange of heat, moisture and momentum between the surface and the atmosphere takes place. LÄS MER

  7. 5. Land-atmosphere interactions and regional Earth system dynamics due to natural and anthropogenic vegetation changes

    Författare :Minchao Wu; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :land-atmosphere interactions; RCA-GUESS; LPJ-GUESS; Vegetation dynamics; Fire;

    Sammanfattning : Observation and modelling studies have indicated that the global land surfaces have been undergoing significant changes in the past few decades, driven by both natural and anthropogenic factors, such as changes in ecosystem productivity, fire and land use. Land surface changes can potentially influence local and regional climate through land-atmosphere interactions. LÄS MER
