  1. 1. Optically Stimulated Luminescence Dating and Last Glacial Climate Reconstruction from the Lingtai Loess Section, Chinese Loess Plateau

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emma Lagerbäck Adolphi; [2016]
    Nyckelord :Last Glacial; optical stimulated luminescence dating; Chinese loess plateau; Lingtai; magnetic susceptibility; mass accumulation rate; climate reconstruction;

    Sammanfattning : High resolution dating of loess on the Chinese Loess Plateau (CLP) using Optically Stimulated Luminescence (OSL) has increased the understanding of past monsoon climate but also raised questions regarding dust mass accumulation rate (MAR), the presence of disturbances or gaps in the sediment record, a possible teleconnection between North Atlantic and East Asian monsoon climate, and whether these events are due to climate variability, local settings, or age model uncertainties. This study undertakes a detailed (<20cm sampling resolution) -OSL investigation of the Lingtai section to create an independent age model using linear regression, to reconstruct monsoon climate changes using magnetic susceptibility(MS) and grain size (GS) proxies, as well as to calculate MAR for the site.

  3. 2. Afrikas klimat - med fokus på Västafrika

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Eric Sönnert; [2014]
    Nyckelord :African easterly waves; climate; convection; ITCZ; monsoon; tropics; West Africa; Klimat; ITCZ; konvektion; monsun; ostliga vågor; tropikerna; Västafrika;

    Sammanfattning : Då de flesta människor i Västafrika, framför allt de som bor innanför kustzonen, livnär sig på jordbruk så är pålitliga väderprognoser och säsongsförutsägelser ett viktigt hjälpmedel i det dagliga arbetet och planeringen. I den här rapporten har en litteraturstudie gjorts för att öka kunskapen om de komplexa, både lokala och storskaliga, väderfenomen som ger upphov till nederbörd i området. LÄS MER

  4. 3. Investigations of a stalactite from Al Hota cave in Oman and its implications for palaeoclimatic reconstructions

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Donna Bou-Rabee; [2013]
    Nyckelord :vätskeinneslutningar; droppstenar; Arabien; Oman; Al Hota; monsoon; speleothem; cave; isotope; climate; monsun; ITCZ; Earth and Environmental Sciences;

    Sammanfattning : Speleothems and other cave sediments have proven to be valuable tools for climate reconstructions. They allow to reconstruct the changes of temperatures and precipitation over time even in arid areas where other types of sedimentary archives are scarce or even non-existent. LÄS MER

  5. 4. Statistical Characteristics of Convective Storms in Darwin, Northern Australia

    Magister-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Nyckelord :convective storms characteristics; precipitation; radar; monsoon; Australia;

    Sammanfattning : This M. Sc. thesis studies the statistical characteristics of convective storms in a monsoon regime in Darwin, northern Australia. It has been conducted with the use of radar. LÄS MER
