  1. 1. Co-occurring Cold Extremes in North America and Unusually Warm Weather in Europe

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Petros Stergiou; [2023]
    Keywords : Extreme temperature events co-occurrence; cold spells; warm extremes; Europe; North America; Pan-Atlantic atmospheric teleconnections; Samtidiga extrema temperaturhändelser; kalla extrema; varma extrema; Europa; Nordamerika; Pan-Atlantiska atmosfäriska telekopplingar;

    Abstract : In this project, we identified and examined the 50 coldest extreme temperature eventsin North America (CENA) and the 50 warmest extreme temperature events insouthwestern Europe (WEEU) during the winter seasons from 1948 to 2023. For theanalysis, we utilized daily NCEP-NCAR reanalysis data for temperature, sea levelpressure (SLP), and 500hPa geopotential height (Z500). READ MORE

  3. 2. Regional Precipitation Study in Central America, Using the WRF Model

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Tito Maldonado; [2012]
    Keywords : WRF; Central America; precipitation; dynamical downscaling; regional models; reanalysis; cumulus parameterization schemes.; WRF; Centralamerika; nederbörd; dynamiska nedskalning; regionala modeller; reanalys; cumulus parametrisering system;

    Abstract : Using the regional climate model WRF, and the NCEP-NCAR Reanalysis Project data asboundary and initial conditions, regional precipitation was estimated by means of thedynamical downscaling technique for two selected periods, January 2000 and September2007. These months show very particular climatic characteristics of the precipitationregimen in Central America, like dry (wet) conditions in the Pacific (Caribbean) coast of theCentral American isthmus, in January, and wet (dry) conditions, respectively in each coast,during September.

  4. 3. Statistical analysis of wind data regarding long-term correction

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Christoffer Jonsson; [2010]
    Keywords : MATLAB; Measure-Correlate-Predict; Regression; NCAR NCEP; Seasonal dependence; Long-term Correction; Wind Analysis; MATLAB; Measure-Correlate-Predict; Regression; NCAR NCEP; Säsongsberoende; Långtidskorrigering; Vindanalys;

    Abstract : The procedure of determining if a site is suitable for wind power production requiresconvincing statistical data describing the long-term behavior of the average wind speed.This can be achieved by measuring the wind speed for a short time period, e.g. a year,and after that a Measure-Correlate-Predict (MCP) method can be performed.

  5. 4. Wind Climate Estimates - Validation of Modelled Wind Climate and Normal Year Correction

    University essay from Luft- och vattenlära

    Author : Martin Högström; [2007]
    Keywords : Modelled Wind Climate; MIUU-model; Normal Year Correction; Wind Energy;

    Abstract : Long time average wind conditions at potential wind turbine sites are of great importance when deciding if an investment will be economically safe. Wind climate estimates such as these are traditionally done with in situ measurements for a number of months. READ MORE

  6. 5. Downscaling of Wind Fields Using NCEP-NCAR-Reanalysis Data and the Mesoscale MIUU-Model

    University essay from

    Author : Mattias Larsson; [2006]
    Keywords : dynamic downscaling; wind field; NCEP NCAR reanalysis; MIUU-model;

    Abstract : The profitability from the production wind power energy is related to the quality of the wind speed forecasts. All wind predicting methods needs meteorological data, for the prevailing synoptic situation, as input. High quality input is wanted for a better result. READ MORE
