Trends and multi-annual variability of water temperatures in the river Danube, Serbia

摘要: The relationship between air (Ta) and water temperature (Tw) is very important because it shows how the of a body might respond to future changes in surface Ta. Mean monthly Tw records three gauging stations (Bezdan, Bogojevo i Veliko Gradiste) were analysed alongside mean discharge (Q) for same stations. Additionally, Ta series from two meteorological (Sombor correlated with variations over period 1950–2012. Locally weighted scatter point smoothing (LOWESS) was used investigate long-term trends raw data, Mann–Kendall (MK) trend test. Trend significance established using Yue–Pilon's pre-whitening approaches determine climate data. Also, rescaled adjusted partial sums (RAPS) method detect dates possible time series.
