  1. 11. Impact of climate variability on dynamic groundwater storage in mid- to high latitude countries

    Författare :Michelle Nygren; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; time series analysis; groundwater statistics; Sweden; drought; cold region hydrogeology; groundwater memory;

    Sammanfattning : Climate change will alter the hydrological cycle, potentially changing dynamic groundwater storage and increasing groundwater drought risk. Climate influences groundwater storage directly via changes in groundwater recharge, but groundwater drought responsiveness further depends on groundwater system characteristics. LÄS MER

  3. 12. 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

  4. 13. On the intra-seasonal to decadal climate variability over South-Asia

    Författare :Faisal Saeed Syed; Heiner Körnich; Erik Kjellström; Jagadish Shukla; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; South Asia; monsoon; western disturbances; fog; climate variability; climate dynamics; teleconnections; ENSO; NAO; CGT; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : South Asia, a land of contrasting landscapes, seasons and climates, is highly vulnerable to climate variability over intra-seasonal to decadal time scales. In winter, precipitation over the western parts of south Asia and fog over the Indo-Gangetic (IG) plains are the two major climatic features. LÄS MER

  5. 14. Climate vulnerability assessment methodology : Agriculture under climate change in the Nordic region

    Författare :Lotten Wiréhn; Tina-Simone Schmid Neset; Björn-Ola Linnér; Giuseppe Feola; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agriculture; Assessment methodology; Climate change; Geographic Visualization; Indicator-based methods; Vulnerability; Bedömningsmetodologi; Geografisk Visualisering; Indikatorbaserade metoder; Jordbruk; Klimatförändringar; Sårbarhet;

    Sammanfattning : Food security and climate change mitigation are crucial missions for the agricultural sector and for global work on sustainable development. Concurrently, agricultural production is directly dependent on climatic conditions, making climate change adaptation strategies essential for the agricultural sector. LÄS MER

  7. 15. Inter-annual variability of rainfall in Central America : Connection with global and regional climate modulators

    Författare :Tito Maldonado; Björn Claremar; Eric J. Alfaro; Jorge A. Amador; Michael Taylor; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Precipitation; climate variability; El Niño Southern Oscillation; Tropical North Atlantic; Canonical Correlation Analysis; EC-EARTH; Caribbean Low-Level Jet;

    Sammanfattning : Central America is a region regularly affected by natural disasters, with most of them having a hydro-meteorological origin. Therefore, the understanding of annual changes of precipitation upon the region is relevant for planning and mitigation of natural disasters. LÄS MER
