The application of piecewise ITA method in Oxford, 1870–2019

In this study, the trends, stabilities of temperature, and rainfall data have been analyzed in detail for hydrometeorology time series recorded since 1870 Oxford city England. The innovative trend analysis (ITA) method has used to identify analyze piecewise trends selected series. To compare results, modified Mann–Kendall (MMK) Sen’s slope (SS) methods applied each as a ITA application. obtain reliable objective conclusions, ± 5% 10% percentage lines considered application method. provides more detailed information compared studies literature such MMK. Identification that implies climate change is taken into consideration by approach future design purposes. available with record length 150 years divided sub-series 30 considering last 30-year period which began be discussed due its significant effects. As result, when are examined different partial series, it seen temperature increase 1990–2019 much higher than past 120 years. highest average occurred 1900–1929 periods, their amounts nearly similar.
