Zanesljivost napovedi proizvodnje energije kombiniranih vetrnih in sončnih elektrarn
Alenka Senica, Nedjeljka Žagar, Mark Žagar
Magistrsko delo
Oznake: obnovljivi viri energije;vetrna energija;sončna energija;verifikacija vremenskih napovedi;mejna plast;vetrovi;sevalnost;obsevanost;
Za enostavnejši prehod iz fosilnih goriv na obnovljive vire energije in s tem nizkoogljično družbo potrebujemo zanesljive napovedi o hitrosti in moči vetra, obsevanosti oziroma moči sončnega sevanja. Te napovedi omogočajo načrtovanje obratovanja vetrnih, sončnih ali kombiniranih elektrarn in integra ...

Assimilation of spaceborne Doppler wind lidar observations in a mesoscale model
Matic Šavli, Nedjeljka Žagar
Doktorska disertacija
Oznake: meteorology;weather prediction;satellite wind observations;Aeolus satellite;Doppler lidar;horizontal line-of-sight winds;limited area modelling;data assimilation;Kalman filter;
A continuous improvement of weather prediction is the most important activity of the most of meteorological research. Numerical Weather Prediction (NWP) is the initial value problem, in addition dependent on the quality of numerical model. The NWP improvements rely substantially on the quality at ...

Coupling of the aerosols, moisture and winds in 4D-Var data assimilation for Numerical Weather Prediction
Žiga Zaplotnik, Nedjeljka Žagar
Doktorska disertacija
Oznake: meteorology;numerical weather prediction;variational data assimilation;4D-var;wind tracing;tropical data assimilation;humidity;aerosols;
The increasing amount of remotely sensed data on atmospheric trace constituents has been provided by satellites in recent years as well as numerous vertical temperature and moisture profiles in form of radiances. This trend is going to continue with the launch of the Aeolus and EarthCARE satellites. ...

Normal-mode analysis of the role of tropics in global atmospheric predictability
Katarina Kosovelj, Nedjeljka Žagar
Doktorska disertacija
Oznake: meteorology;numerical modeling;general atmospheric circulation;atmospheric predictability;normal modes;Madden-Julian oscillation;
Tropical circulation features associated with convective heating affect the extratropical variability trough various teleconnections. Some properties of this tropical-extratropical coupling are addressed in this thesis. The novelty of the applied methodology is the modal decomposition technique that ...

ǂAn ǂintermediate-complexity model for four-dimensional variational data assimilation including moist processes
Žiga Zaplotnik, Nedjeljka Žagar, N. Gustafsson
Izvirni znanstveni članek
Oznake: meteorologija;atmosferska dinamika;vlažnost zraka;veter;meteorology;atmospheric dynamics;moisture;wind;
This article presents a new Moist Atmosphere Dynamics Data Assimilation Model (MADDAM), an intermediate‐complexity system for four‐dimensional variational (4D‐Var) data assimilation. The prognostic model equations simulate nonlinear moisture advection, precipitation, and the impact of condensational ...

Vpliv vertikalne turbulentne difuzije v modelu CAMx na izračunane koncentracije onesnaževal
Luka Matavž, Nedjeljka Žagar, Rahela Žabkar
Magistrsko delo
Oznake: meteorologija;onesnaženost zraka;napovedovanje kakovosti zraka;vertikalna turbulentna difuzija;numerično modeliranje;
Napoved kakovosti zraka je odvisna od meteoroloških pogojev, posebej v planetarni mejni plasti (PBL). Zato so modeli za kakovost zraka sklopljeni s meteorološkimi modeli. Od posebnega pomena za uspešnost napovedi kakovosti zraka je parametrizacija turbulence v mejni plasti, tako v meteorološkem mode ...
