  1. 1. Urban Trees : A case study in central Umeå

    Magister-uppsats, Umeå universitet/Institutionen för geografi

    Författare :Maria Sundelin; [2023]
    Nyckelord :Urban trees; canopy cover; i-Tree Canopy;

    Sammanfattning : Urban trees are crucial to a healthy environment. The benefits range from good air quality to storm water management and public health. The aim of this thesis was to study urban trees in Umeå city. Umeå is in a process of densification and has a vision to increase in population to 200 000 by the year 2050. LÄS MER

  3. 2. Analysis of High and Low Rossby Wave Phase Speed Events Over Northern Mid-Latitudes

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Emma Rosengren; [2022]
    Nyckelord :Rossby waves; phase speed; atmospheric blocking; storm track; windstorms; Rossbyvågor; fashastighet; atmosfärisk blockering; lågtrycksbana; vindstormar;

    Sammanfattning : The large-scale, mid-latitude circulation in the upper troposphere is dominated by Rossby waves. The jet stream flows along the wave structure and surface cyclones can be found ahead of the troughs of the waves, propagating eastward. LÄS MER

  4. 3. Analysis of Observed Discrepancies in Precipitation Measurements in the Complex Terrain of East-Iceland

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Páll Ágúst Þórarinsson; [2021]
    Nyckelord :Precipitation; precipitation measurements; weather observation; complex terrain; weather regimes; Iceland; Nederbörd; nederbördmätningar; väder observationer; komplex terräng; vädersituationen; Island;

    Sammanfattning : Spatial distribution of precipitation in complex terrain can be very uneven and there are many factors to consider when studying it. The goal of this study was such a problem; to analyse the difference in observed annual precipitation in the complex terrain of Seyðisfjörður, a fjord in East-Iceland. The study was carried out in three parts. LÄS MER

  5. 4. Study on future storm surge around Suo-nada Sea

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Ayano Sonoda; [2019]
    Nyckelord :storm surge; Suo-nada Sea; numerical simulation; FVCOM; Technology and Engineering;

    Sammanfattning : Japan lies on an area frequently hit by typhoons while city functions are clustered along the flat coastal areas, hence Japan has experienced lots of storm surge disasters up to the present. Coastal areas along the Suo-nada Sea also have the vulnerability against storm surge and in the past Typhoon 18 in 1999, Typhoon 16 and 18 in 2004 made remarkable damages in the areas. LÄS MER

  7. 5. Evaluation of X-band Weather Radar Data in Urban Hydrology

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Alva Kalm; Camilla Hedell; [2019]
    Nyckelord :Urban hydrology; X-band radar; Bias correction; Error analysis; Neural network; Scania.; Technology and Engineering;

    Sammanfattning : Throughout history it has always been crucial to accurately measure, track, and predict precipitation. This has been done using various methods with varying degrees of precision. As the world evolves and as urban areas expand, it has become more apparent that there is a need for a more efficient way to observe and record precipitation. LÄS MER
