Abstract

Sofia is 1.5 million citizens city situated in a mountain valley and thus characterised with complex structure of the planetary boundary layer (PBL) caused by both terrain and urban features. Stagnant stable conditions lead to fogs and smog in winter, and dry climate leads to high PM concentrations in summer albeit the deep PBL. In this study we evaluated the dynamics given by two configurations of the Weather Research Forecasting (WRF) model against data from consecutive high vertical resolution radiosoundings during 5 days in Sofia under early autumn convective conditions in PBL (Sofia Experiment 2003). Statistical comparisons between modelled and measured parameters showed that WRF simulated relative humidity, temperature and wind direction better in the transition than in the afternoon hours, while the wind speed was insignificantly better simulated in the afternoons. We found that WRF with Mellor-Yamada-Janjic PBL scheme simulated relatively well the vertical profiles of all analysed parameters, except for wind direction which was poorly resolved in the lowest 1,000 m above ground.
