  1. 1. Advancing understanding of tropical forest carbon dynamics through improved allometric models for palms: A case study with Prestoea montana in Puerto

    Magister-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Paschalis Chatzopoulos; [2021]
    Nyckelord :Above ground biomass; allometry; Luquillo Forest Dynamics Plot; Palms;

    Sammanfattning : Tropical forests are major components of Earth’s carbon stocks, but their diversity and structural complexity pose major challenges for making accurate estimates of their above ground biomass (AGB). Palms, in particular, are prominent and unique components of many tropical forests that have anatomical and physiological differences from dicot trees which affect their height - diameter allometry and consequently, our ability to accurately estimate their AGB.

  3. 2. Hindcast of the wave climate in Öresund : modelling of wave climate over 50 years using WAM with wind measurements input

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Laury Renac; Sara Schömer Ericsson; [2014]
    Nyckelord :Wave climate modelling; WAM; Öresund; Earth and Environmental Sciences;

    Sammanfattning : Öresund is a very dynamic economic area with numerous projects, there is a great need of a deeper understanding of the wave climate. The wave measurements currently available are scarce and they do not cover the whole area. LÄS MER

  4. 3. Wave atlas along the south-eastern coast of Sweden : A 6-year simulation of waves using local wind measurements from meteorological stations around the Baltic Sea

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Sebastian Irminger Street; [2011]
    Nyckelord :Baltic Sea; wave modelling; WAM; forcing through wind measurements; wave climate; Technology and Engineering;

    Sammanfattning : A wave atlas describing the monthly wave climate at 5 locations along the Swedish SE coast was desired. Using the WAM wave model to hindcast the waves between Jan 1st 2004 and Dec 31st 2009 the parameters significant wave height, direction of wave propagation and spectral wave peak period were extracted from the time series and assembled in a wave atlas.

  5. 4. Wind Speed Prediction using Global and Regional Based Virtual Towers in CFD Simulations

    Magister-uppsats, Institutionen för kultur, energi och miljö

    Författare :Roger Moubarak; [2011]
    Nyckelord :Global-Regional Global Model; Era Interim; StormGeo; WRF; ECMWF; Data Series; WindSim; Hindcast;

    Sammanfattning : Wind farm assessment is a costly and time consuming process when it is planned by traditional methods such as a met mast. Therefore, new models have been established and used for the wind farm assessment to ease the process of wind farm planning. These models are Global-regional models which add to cost efficiency and time saving. LÄS MER

  7. 5. Validation of the WAM-model over the Baltic Sea

    Uppsats för yrkesexamina på grundnivå, Institutionen för geovetenskaper

    Författare :Caroline Berg; [2008]
    Nyckelord :WAM-model; waves; ERA40; RCA; hindcast; Meteorology; WAMDI; spectral energy balance equation; bias; rms; buoy; ; Sinificant wave height; direction; peak period; Baltic Sea;

    Sammanfattning : In order to understand how waves influence the exchange of momentum, latent heat and other parameters, between the ocean surface and the atmosphere, one can use models. A coupling between a wave model and an atmospheric regional climate model, for the Baltic Sea, will be performed at the Meteorology Institute in Uppsala University. LÄS MER
