  2. 2. Climate and dengue fever : early warning based on temperature and rainfall

    Författare :Yien Ling Hii; Nawi Ng; Joacim Rocklöv; Rainer Sauerborn; Sven Britton; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dengue fever; temperature; rainfall; forecasting model; early warning; epidemic; dengue risk index; folkhälsa; Public health;

    Sammanfattning : Background: Dengue is a viral infectious disease that is transmitted by mosquitoes. The disease causes a significant health burden in tropical countries, and has been a public health burden in Singapore for several decades. Severe complications such as hemorrhage can develop and lead to fatal outcomes. LÄS MER

  3. 3. On Sahelian-Sudan rainfall and its moisture sources

    Författare :Abubakr A. M. Salih; Qiong Zhang; Michael Tjernström; Alessandra Giannini; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Sudan; Sahel; rainfall; land use; deforestation; moisture sources; moisture transport; Lagrangian; moisture tagging; regional model; climate modeling; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The African Sahel is one of the most vulnerable regions to climate variability at different time scales. It is an arid to semi-arid region with limited water resources. The summer rainfall is one of these sources, but it exhibits pronounced interannual variability. This thesis presents several aspects of Sahelian Sudan rainfall. LÄS MER

  4. 4. The Use of Press Archives in the Temporal and Spatial Analysis of Rainfall-Induced Landslides in Tegucigalpa, Honduras, 1980-2005

    Författare :Elias Garcia-Urquia; Kristofer Gamstedt; José Cepeda; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; press archives; landslide database; urban landslides; critical rainfall intensity; antecedent rainfall; rainfall frequency contour lines; matrix method; landslide susceptibility index; Tegucigalpa; Honduras; Hurricane Mitch; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Sammanfattning : The scarcity of data poses a challenging obstacle for the study of natural disasters, especially in developing countries where the social vulnerability plays as important a role as the physical vulnerability.  The work presented in this thesis is oriented towards the demonstration of the usefulness of press archives as a data source for the temporal and spatial analysis of landslides in Tegucigalpa, Honduras for the period between 1980 and 2005.

  5. 5. Water erosion modeling using fractal rainfall disaggregation- a study in semiarid Tunisia

    Författare :Sihem Jebari; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reservoir siltation; regionalization; fractal analysis; Atlasic mountain range; erosive events; semiarid area; soil loss; Tunisia.; Soil erosion; semiarid; Tunisia; rainfall; fractal; diaggregation;

    Sammanfattning : In the Tunisian semiarid area, water erosion processes have led to negative economic and environmental consequences in a context of limited water resources. To characterize and predict these degradation phenomena, a comprehensive high-resolution data base on erosive rainfall, together with siltation records for 28 small reservoirs were analyzed. LÄS MER
