Abstract

Klimatske promjene utječu na poljoprivrednu proizvodnju, a time i na ekonomske prilike nekog područja. Promjene klime uključuju varijabilnost u količini oborina, intenzitetu vjetrova i porastu temperature. Oborine zabilježene na nekom području uglavnom potječu od vlage pristigle s područja mora i oceana, no smatra se da je čak jedna trećina oborina lokalnog porijekla proistekla od evaporacije („reciklirana vlaga“).
Regionalne studije za područje Mediterana pokazale su da u drugoj polovici 20-tog stoljeća postoji opći trend smanjenja količina oborina, a predviđanja su da će se taj trend nastaviti. Stoga su na primjeru otoka Visa, tijekom petogodišnjeg razdoblja, korištenjem HYSPLIT modela i primjenom kalkulacija za utvrđivanje izdizanja vlage zraka izračunate unazadne putanje zračnih masa, lokacije izdizanja vlage i udio reciklirane vlage zraka u ukupnoj količini oborina.

Abstract (english)

Climate changes directly affect agricultural production and economy of certain area. Changes of climate include variability of rainfall, wind intensity and increase of temperature. Precipitation collected on a specific location is mostly derived from sea and ocean moisture, although it is considered that approximately one-third of precipitation is derived from locally originated moisture by evaporation (recycled moisture).
Regional studies for the Mediterranean area have shown a general trend of decrease of amount of precipitation in the second half of 20th century. Furthermore, predictions show that this trend will continue. In order to investigate this we used HYSPLIT model to calculate back trajectories of air masses bringing precipitation over Vis Island, Croatia. Application of calculations for specific humidity allowed us to determine locations of moisture uptake and percentage of recycled moisture in precipitation.
