“…Because the climate change had a large impact on water management, our investigations were realized also in large river basins. Similar idea have given birth to investigations in the Yangtze River [ZHANG et al 2014], as well as in the Betwa Basin in India [SURYAVAVANSHI et al 2014].…”

No. 27 p. 3-13. AbstractThe variability of the mean annual air temperature and precipitation totals in three periods: 1848-2010, 1951-2010 and 1981-2010 was investigated in the large Warta River basin, being the area with lowest rainfall in Poland. For the purposes of research, nine meteorological stations with the longest measurement series were selected. Air temperature increase in this river basin was similar than in neighbouring countries. In the last 30 years this trend kept increasing. The precipitation in the whole studied period was slightly increasing in the northern part of the Warta River basin, but decreasing in the southern part. The mean annual precipitation totals in the catchment area did not change visible. In the period 1981-2010, the precipitation totals show a small increase in the winter and spring and a decrease in summer. A negative influence of this climate change was not visible in the Warta River discharge. The main objectives of this study were the collection long-term records of air temperature and precipitation in the Warta River basin, and the statistical analysis of climate variability.

“…also went on to identify the change point into the time series. Long term historic changes in the climatic variables of the Betwa basin was studied with the help of MMK test by Suryavanshi et al (2014) which gave mixed results. Some stations in the basin observed decreasing rainfall and increasing trend for all stations in minimum temperature whereas, winter season witnessed increasing trend both in maximum and minimum temperature (op.…”

Present study evaluates the vegetation responses towards the rainfall variability in the Gomati basin during 1901-2015. To accomplish the same, high resolution observed daily gridded rainfall data from India Meteorological Department (IMD) was analysed using non-parametric trend test. The long-term rainfall showed significant decreasing trend (α=0.05) which varied from -0.96 to -4.89 per year. Identified trends in rainfall were then evaluated in tandem with the basin-wide changes in the vegetation signatures during the recent extreme years (two pairs of dry and wet years). Each pair of extreme years was assessed for its seasonal Normalised Difference Vegetation Index (NDVI) related to the seasonal rainfall variations with special emphasis to rice and wheat yields (major crops). Contribution of spatio-temporal occurrences of rainy days with that of the heavy rainfall events was also analysed. The findings suggest that the prevalent basin-wide longterm rainfall deficiency intensified during the extreme dry years e.g. 2002 and 2009 and impacted the health of vegetation in the basin. Vegetation of the basin was found closely related with rainfall variability; regular and well distributed occurrences of rainy days benefited the basin's vegetation as well as the yields of rice and wheat crops.

“…In case of presence of serial correlation in the hydrological time series increase the probability that the non parametric test will detects the significant trend (Kulkarni and Von Storch 1995). However, this approach has been widely used in several earlier works related to long-term climatic variation (Rodhe and Virji 1976;Nicholson and Palao 1993;Türkes et al 2002;Partal and Kahya 2006;Hamed 2009;Suryavanshi et al 2014;Kundu et al 2014Kundu et al , 2015. To test the persistence in the climatologically time series, normalized anomaly of the time series are used.…”

“…Change in climate over the India by southwest monsoon causes drastic change in hydrological parameters such as precipitation, evaporation and streamflow, would have a significant impact of agricultural production, water resources management and overall economy of the country (Dvorak et al 1997;Lal 2001;Eckhardt and Ulbrich 2003;Gosain et al 2006;Jiang et al 2007;IPCC 2007;Kalra et al 2008;Jain and Kumar 2012;Sonali and Kumar 2013). Therefore, trend analysis of long-term hydrologic, as well as climatic data has been extensively used to assess the potential impacts of climatic change and variability (Rupakumar and Hingane 1988;Rao and Kumar 1992;Chen et al 1992;Hingane 1995;Pant and Kumar 1997;Kadioglu 1997;Sadhukhan et al 2000;Lu et al 2004;Arora et al 2005;Gadgil and Dhorde 2005;Tomozeiu et al 2006;Singh et al 2008;Subash et al 2011;Jain and Kumar 2012;Suryavanshi et al 2014;Kishore et al 2016).…”

The present study has been carried out for longterm trend analyses of past climatic variables using nonparametric tests (MK test, sequential Mann-Kendall and Theil-Sen's slope) for the Giridih district in Jharkhand (India). In addition, sequential Mann-Kendall test were used to see change with time. However, in the serially correlated series, pre-whitening has been used before employing the MK test. The long-term trend analysis based on meteorological station to exhibit a trend in annual and seasonal precipitation for the study area. It was found that there was no significant trend observed in monsoon and summer session for maximum and minimum temperature. Whereas, a significant increasing trend in the region was observed for the winter season. Hence, rainfall is concerned; there was a significant decreasing trend of 2.04 mm/year observed during the monsoon season. There were good agreements with all climatic variables corresponding to the statistical analysis.
