The most important impacts of climate change relate to temperature and precipitation. Precipitation is particularly important, because changes in precipitation patterns may lead to floods or droughts in different areas. Also, precipitation is a major factor in agriculture and in recent years interest has increased in learning about precipitation variability for periods of months to annual and s...
Temperature and rainfall are important meteorological variables in connection with changes the climate. Analyzing temperature is a necessary first step determining how climate change will affect us. Evaluating would accessibility of water environment. The main focus current study on shifting patterns Kharun Watershed, Chhattisgarh. Mann-Kendall (MK) test Sen's slope (SS) method used this to exa...
This study investigated trends in hydro-climate data (precipitation, maximum/minimum temperatures, and streamflow) for the period 1980–2016 around a semi-arid Hadejia-Nguru wetlands (HNWs) Northern Nigeria. Four meteorological stations (Bauchi, Kano, Hadejia, Nguru) three streamflow gauge statins (Hadejia, Katagum, Gashua) were used to cover HNWs’ catchment. The was checked normality using Ande...
Identification of trend and drought characteristics play an important role in the development and management of water resources. In this study, the spatio-temporal characteristics of SPEI index in short, medium, long and annual scales (SPEI3, SPEI6 and SPEI9) in Urmia Lake basin were investigated. for this purpose, temperature and precipitation data from 4 synoptic stations of Tabriz, Urmia,...
This article aims to review studies pertaining to trends in rainfall, rainy days and temperature over India. Sen’s non-parametric estimator of slope has been frequently used to estimate the magnitude of trend, whose statistical significance was assessed by the Mann–Kendall test. Spatial units for trend analysis vary from station data to sub-division to sub-basin/ river basins. There are differe...
