  1. 6. A combined carbon and hydrogen isotope approach to reconstruct the SE Asian paleomonsoon : Impacts on the Angkor Civilization and links to paleolimnology

    Författare :Kweku Kyei Afrifa Yamoah; Rienk Smittenberg; Sarah Feakins; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Holocene; summer monsoon; biomarkers; hydrogen isotopes; lake sediment; peat; Thailand; geokemi; Geochemistry;

    Sammanfattning : Changes in monsoon patterns not only affect ecosystems and societies but also the global climate system in terms of heat energy and humidity transfer from the equator to higher latitudes. However, understanding the mechanisms that drive monsoon variability on longer timescales remains a challenge, partly due to sparse paleoenvironmental and paleoclimatic data. LÄS MER

  3. 7. Towards an improved understanding of precipitation variations over the Tibetan Plateau

    Författare :Hui-Wen Lai; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Third Pole; Tibetan Plateau; precipitation; Asian summer monsoon; westerly jets; Regional Climate Model; satellite observation;

    Sammanfattning : The Tibetan Plateau (TP) and surrounding regions are known as the ``Third Pole'' because of their polar-like environment and large reservoirs of fresh water. Due to the latter aspect, the TP is also considered the ``Water Tower of Asia'', providing essential water resources to the surrounding regions. LÄS MER

  4. 8. Reconstruction of the Southeast Asian hydro-climate using biomarkers and their hydrogen isotopic composition

    Författare :Yamoah Kweku Kyei Afrifa; Rienk Smittenberg; Barbara Wohlfarth; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geokemi; Geochemistry;

    Sammanfattning : Southeast Asia is characterized by a monsoonal climate, with distinct wet and dry seasons. This has great impact on societies, agriculture and infrastructures. LÄS MER

  5. 9. Paleoclimate and seasonality on Sumatra during the Late Glacial and Holocene : Insights from biomarkers and climate model simulations

    Författare :Lars Petter Hällberg; Malin Kylander; Frederik Schenk; Rienk Smittenberg; David Naafs; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Holocene; Late Glacial; biomarkers; organic geochemistry; climate model; hydrogen isotopes; stable isotopes; paleoclimate; alkanes; GDGT; brGDGT; H-GDGT; bacterial community shifts; paleothermometry; precipitation reconstruction; peat; geokemi; Geochemistry;

    Sammanfattning : Deep atmospheric convection in the Indo-Pacific Warm Pool (IPWP) is a key driver of the Hadley and Walker Circulations that modulate the Asian-Australian monsoons and the El Niño Southern Oscillation (ENSO). Temperature and rainfall seasonality, i.e. LÄS MER

  7. 10. Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change

    Författare :Juan Camilo Acosta Navarro; Ilona Riipinen; Annica M.L. Ekman; Hans-Christen Hansson; Risto Makkonen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; Air quality; Land use; General circulation; Atmosphere-Ocean interactions; Aerosol climate effects; Earth system modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. LÄS MER
