Temperature changes on the Earth and in Serbia and North Atlantic oscillation (NAO)

Abstract

In this paper connection between temperature changes and North Atlantic oscillation (NAO) has been investigated in the period from 1979 until 2006. Satellite temperature data from UAHMSU were investigated in relation to North Atlantic Oscillation index on the Earth, in Europe and in Serbia. Statistically insignificant correlation coefficient has been obtained for the area of Serbia. The analysis of periodicity of 2.8±0.5 year is in accordance with that one obtained by Landschieidt (2001). However, in order to give final conclusion regarding to climate change more parameters should be analyzed.

U radu je istraživana veza između temperature vazduha i Severno atlantske oscilacije (NAO) u svetu , u periodu od 1979. do 2006. godine. Ispitivana je veza između satelitskih podataka temperature vazduha UAHMSU i NAO indeksa na prostoru Srbije (17.5-22.5°E i 42.5-47.5°N ), u Evropi (10-45°E i 35-70°N) i svetu po pojasevima od po 10° geografske širine. Uočen je statistički nesignifikantan koeficijent korelacije za prostor Srbije. Analiza elementarne periodičnosti je pokazala da u posmatranom periodu prosečna dužina osnovne periode za MSU od približno 2.8±0.5 godina, odgovara periodičnosti varijanse NAO, koju je dao Landschieidt (2001). Ipak, u isticanju mogućih uzroka savremenih kolebanja klime trebalo bi istovremeno analizirati više parametara cirkulacije atmosfere.
