Landspout across Novi Beograd, 24 may 2012: Synoptic analysis

Abstract

In this study we have analysed a case of the landspout across Novi Beograd on 24 May 2012. We have used a synoptic analysis method in the research and the description of the landspout event is based on visual evidence and photographs. According to the available data, it can be concluded that there were favourable conditions for a landspout development since there was a process and an increased amount of instability. The landspout occured within the northeast stream which moved over Belgrade and further toward the southeast and west. Based upon synoptic data analysis, it can't be said that there was a cold air advection. Surface air was warm enough, but not the air in the upper layers of the atmosphere. The conditions for a landspout development were favourable - high relative air humidity and increased vertical and horizontal air currents.

U radu je prikazan slučaj pojave trombe 24.05.2012. na Novom Beogradu. U istraživanju je korišćen metod sinoptičke analize, a opis pojave trombe temelji se na vizuelnom opažanju i fotografijama. Prema raspoloživim podacima može se zaključiti da su uslovi za razvoj trombe bili povoljni, jer je postojao i proces i povećana energija nestabilnosti. Tromba se javila u sklopu severoistočne struje koja se premeštala preko Beograda dalje na jugozapad i zapad. Na osnovu analize sinoptičkog materijala, ne može se reći da se radilo o advekciji jako hladnog vazduha. Bilo je dovoljno toplote u prizemlju, ali ne i po visini. Postojali su povoljni uslovi za nastanak trombe - visoka vlažnost vazduha, izražena vertikalna i horizontalna strujanja.
