  1. 1. "Share weather" : Design and evaluation of a new concept for sharing weather information

    Författare :Katarina Elevant; Stefan Hrastinski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Already centuries ago, humans had observed the weather in their everyday lives, seeking ways to understand, comprehend, and predict it. Until the present day, weather has had tremendous impacts on our lives and with climate change human civilizations as well. LÄS MER

  3. 2. Microclimate Load: Transformed Weather Observations for Use in Durable Building Design

    Författare :Anneli Högberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microclimate load; weather observations; natural degradation conditions; durable design; transformation;

    Sammanfattning : This study investigates the microclimate load, i.e. conditions prevailing in the immediate atmospheric environment of a building, to establish the natural conditions of degradation for a building surface at a specific location. LÄS MER

  4. 3. Dynamical aspects of coherent eddies in the North Atlantic Ocean : Insights from Satellite Observations

    Författare :Arunraj Kondetharayil Soman; Léon Chafik; Johan Nilsson; Caroline Katsman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Eddy detection and tracking; Ocean heat content; Satellite altimetry; Lagrangian Trajectories; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Oceanic mesoscale eddies, often referred to as the “weather of the ocean”, have horizontal scales of O(10) − O(102) kilometers and timescales spanning days to months. These structures comprise a complex system of coherent eddies (meaning they retain their shape and structure over time and space), filaments, and spirals that influence the transport of heat, salt, and nutrients in the ocean.

  5. 4. The Problem of Partial Migration - the Case of the Blue Tit

    Författare :Anna Nilsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; Djurekologi; Animal ecology; Ekologi; Ecology; weather; personality; partial migration; metabolic rate; evolution of migration; dominance; Cyanistes caeruleus; climate change; blue tit; behavioural strategies; bird migration;

    Sammanfattning : In the evolution of bird migration, partial migration is assumed to be an important intermediate step between migration and residency. Partial migration is characterised by the existence of both migratory and resident individuals in a given population. LÄS MER

  7. 5. Space Weather Physics, Prediction and classification of solar wind structures and geomagnetic activity using artificial neural networks

    Författare :Peter Wintoft; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomi; cosmic chemistry; space research; Astronomy; solar magnetic fields; space weather; solar wind; magnesphere; artificial neural networks; geomagnetic activity; rymdvetenskap; kosmisk kemi; Fysicumarkivet A:1997:Wintoft;

    Sammanfattning : This thesis concerns the application of artificial neural network techniques to space weather physics. The networks applied include multi-layer error-backpropagation, radial basis function, and self-organized maps. LÄS MER
