  1. 1. 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

  3. 2. Short- and long-term variability in future electricity systems – Ensuring the flexibility to manage the grid frequency and inter-annual variations

    Författare :Jonathan Ullmark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inter-annual variability; flexibility; frequency control; battery storage; Electricity systems modelling; capacity expansion planning;

    Sammanfattning : To achieve climate mitigation targets, the net climate impact from electricity generation must be drastically reduced in the near future, and eventually eliminated. The level of generation must also be increased to accommodate the increasing demand as the transport and industry sectors undergo electrification. LÄS MER

  4. 3. The Carbon Dioxide System in the Baltic Sea Surface Waters

    Författare :Karin Wesslander; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; carbon dioxide; pCO2; total alkalinity; pH; air-sea gas exchange; inter-annual; seasonal;

    Sammanfattning : The concentration of carbon dioxide (CO2) in the atmosphere is steadily increasing because of human activities such as fossil fuel burning. To understand how this is affecting the planet, several pieces of knowledge of the CO2 system have to be investigated. LÄS MER

  5. 4. The Effect of Snow on Plants and Their Interactions with Herbivores

    Författare :Mikaela Torp; Johan Olofsson; Christa Mulder; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Snow; arctic ecosystem; plant-herbivore interactions; phenology; nitrogen; phenolics; experimental manipulation; natural gradient; inter-annual variability; Biology; Biologi;

    Sammanfattning : The ongoing climate changes are predicted to accelerate fast in arctic regions with increases in both temperatures and precipitation. Although the duration of snow cover is generally expected to decrease in the future, snow depth may paradoxically increase in those areas where a large amount of the elevated precipitation will fall as snow.

  7. 5. Size-dependent predator-prey interactions, distribution and mortality in salmon: effects on individuals and populations

    Författare :Philip Jacobson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The biomass dynamics of populations is largely determined by the survival, growth, and reproduction of individuals. For fish and other animals, survival, growth, and reproduction depends on the amount of energy an individual obtains via feeding and are therefore food-dependent. LÄS MER
