1. 1. Temporal Consistency of the UERRA Regional Reanalysis: Investigating the Forecast Skill

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

   Author : Adam von Kraemer; [2018]
   Keywords : Temporal consistency; reanalysis; forecast skill; UERRA; HARMONIE; Tidsmässig konsistens; återanalys; prognoskvalitet; UERRA; HARMONIE;

   Abstract : Weather forecasting has improved greatly since the middle of the 20th century, thanks to better forecasting models, an evolved weather observing system, and improved ways of assimilating the observation data. However, these large systematical improvements make it difficult to use the weather data for climatological studies. READ MORE

3. 2. An investigation of the surface fluxes and other parameters in the regional climate model RCA1 during ice conditions

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

   Author : Camilla Tisell; [2004]
   Keywords : RCA; ERA-40; surface fluxes; Baltic Sea;

   Abstract : In this study data from the regional climate model RCA1 is compared to measured data to investigate how good the model is during ice conditions and mainly how well the turbulent surface fluxes are described by the model. Comparisons of the sensible heat flux and the momentum flux as well as mean parameters are included. READ MORE

4. 3. An investigation of the accuracy and long term trends of ERA-40 over the Baltic Sea

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

   Author : Gabriella Nilsson; [2004]
   Keywords : Re-analysis; ERA-40 evaluation; turbulent fluxes; Baltic Sea climate;

   Abstract : Meteorological measurements from the research station at Östergarnsholm in the Baltic Sea between 1995 and 2001 are used to evaluate the ERA-40 data base over the Baltic Sea. This includes comparisons of mean parameters and turbulent fluxes. READ MORE
