1. 1. Global Climatology and Regional Modeling of Coastal Low-Level Jets

   Författare :Muhammad Raza Ranjha; Michael Tjernström; Gunilla Svensson; Branko Grisogono; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coastal low-level jets; climatology; regional modeling; boundary layer; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : Localized coast-parallel wind-speed maxima at low altitude, known as coastal low-level jets (CLLJs) have important ramifications to the coastal climate and a number of human activities. This thesis documents the existence of the CLLJs around the globe including their mesoscale structure, dynamics and spatio-temporal variability. LÄS MER

3. 2. Relationships between Atmospheric Circulation and Wind Erosion in Southern Sweden and Australia

   Författare :Marie Ekström; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Physical geography; geomorphology; Geologi; fysisk geografi; physical geography; Geology; sea level pressure; atmospheric circulation; erosivity; wind erosion; wind climatology; Scania; Australia;

   Sammanfattning : Wind erosion is a serious threat to soil resources as it causes depletion of the fine fractions that may result in a less fertile soil. Wind erosion encompasses several processes of which many are related to climate variables. To date, there is little work performed on how wind erosion relates to climate and climate change. LÄS MER
