    The current study aimed at investigating cycles and the spatial autocorrelation pattern of anomalies of thunderstorms in Iran during different periods from 1961 to 2010. In this analysis, 50-year periods (1961–2010) of thunderstorm codes have been ...
  • Valsson, Trausti (University of Iceland Press, 2006)
    Hnattræn hlýnun (global warming) er eitt mest umrædda málefni í heiminum í dag, enda er hlýnunin þegar farin að hafa gífurlegar afleiðingar. Mikil gögn liggja fyrir um hvernig þættir veður- og náttúrufars eru að breytast. Gefur bókin gott yfirlit yfir ...
  • Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Olafsson, Haraldur (International Society for Aeolian Research, 2016-02-15)
    Iceland has the largest area of volcaniclastic sandy desert on Earth or 22,000 km2. The sand has been mostly produced by glacio-fluvial processes, leaving behind fine-grained unstable sediments which are later re-distributed by repeated aeolian events. ...

    Drought has severe impacts on human society and ecosystems. In this study, we used data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) and Tropical Rainfall Measuring Mission (TRMM) sensors to examine the drought effects on ...
  • Guðlaugsdóttir, Hera; Steen-Larsen, H.C.; Sjolte, J.; Masson-Delmotte, V.; Werner, M.; Sveinbjörnsdóttir, Árný (Elsevier BV, 2018-11)
    The volcanic fingerprint on the winter North Atlantic atmospheric circulation and climate is analyzed in six ensemble runs of ECHAM5/MPI-OM covering 800–2000 CE, both for equatorial and Northern Hemisphere (NH) eruptions. Large volcanic eruptions ...
  • Carneiro, Camilo; Gunnarsson, Tomas Gretar; Alves, Jose (Frontiers Media SA, 2020-06-04)
    For many migratory species, migration can represent a significant part of the annual cycle and the strategies used to move between the breeding and non-breeding areas vary considerably. Weather conditions are important during migration, particularly ...
  • Belart, Joaquín M. C. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2018-11-29)
    The mass balance of a glacier is strongly connected to climate. At high latitudes, mass balance is typically controlled by snow accumulation during the winter and the glacier ablation during the summer. In Iceland, direct mass balance observations ...
  • Guðlaugsdóttir, Hera; Sjolte, Jesper; Sveinbjörnsdóttir, Árný; Werner, Martin; Steen-Larsen, Hans Christian (Informa UK Limited, 2019-07-19)
    Equatorial volcanic eruptions are known to impact the atmospheric circulation on seasonal time scales through a strengthening of the stratospheric zonal winds followed by dynamic ocean-atmosphere coupling. This emerges as the positive phase of the North ...
  • Olafsson, Haraldur; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Magnúsdóttir, Agnes Ösp (MDPI AG, 2016-06-03)
    Particulate matter mass concentrations and size fractions of PM1, PM2.5, PM4, PM10, and PM15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. Images from a camera network were used to estimate the ...
  • Falk, Martin; Hagsten, Eva (MDPI AG, 2018-07-26)
    Recently, several winter seasons in the European Alps have been unexpectedly warm. In the Austrian mountains, December 2015 was the warmest since weather records began, with a temperature deviation of +6.6 °C compared to the long-term average. By use ...
