Trend of the meteorological characteristics and reaction of the daily discharge to snow melt in the small mountain basin

Year, pages: 2018, 42 - 48

The changes in precipitation and air temperature have been observed at majority of the meteorological stations all over the world during the last decades. Some of the meteorological stations with long observation series are influenced by urbanization and changing conditions of the air temperature monitoring. In the paper we analysed the air temperature and precipitation development on anthropogenic uninfluenced stations Podbanske (SK) and Kasprowy Wierch (PL) using the non-parametric Mann-Kendall trend test (MK) and Şen innovative trend method. At the end of the article we tried to confirm or reject the hypothesis about the increase of air temperature during the spring season in the mountain Bela River basin up to Podbanske station. We were analyzing the mean daily discharge series at gauging profile Bela–Podbanske for the period of 1928–2014. We were assuming that the supposed increase of the spring air temperature in the Bela River basin should be proven by earlier arrival of the snowmelt in the basin. The beginning of the flow response to melting snow we defined as the Julian day, when the discharge exceeds a certain threshold. Results of the comparison of both trend tests can be regarded as similar, documented that there is no significant change in this Julian day during the time period 1928–2014.
