Rainfall and evapotranspiration are the two most popular climatic factors which have crucial function on agricultural production. Rainfall can be directly measured easily in an area but evapotranspiration is estimated from weather data. In this study reference evapotranspiration ETo was estimated using Penman–Monteith equation. Monthly rainfall and evapotarnspiration were plotted and compared i...

Drought is widely recognized as a phenomenon associated with scarcity of water. Proper evaluation and management rainfall crucial need to reduce the severity drought. Present work aims study spatial temporal fluctuation in eastern part Satara district Maharashtra using Rainfall Anomaly Index (RAI). Monthly annual data sixteen metrological stations were used for period between 1979 2013. RAI was...

quantitative measurement of meteorological drought, z score(z), rainfall anomaly (rai), standard precipitation (spi) indices and percent of normal precipitation (pnpi) based upon seasonal and annual rainfall data of the 15 meteorological stations of meteorological in hamedan province were used. also, in studying influences of drought on agriculture relative yield index of wheat was used. the re...

Examining the manifestations and effects of climate change is critically dependent on spatiotemporal analysis meteorological variables, particularly in areas where agriculture depends rainfall. The present study analyses temperature rainfall using Mann-Kendall Sen's slope estimator also identifies variations by Rainfall Anomaly Index (RAI). main purpose this to assess variation climatic variabl...

In this research, using technique for order-preference by similarity to ideal solution (TOPSIS) index, drought phenomenon is determined and ranked. For this purpose, using 5 atmospheric elements including temperature, wind, precipitation days, annual precipitation, precipitation concentration index (PCI), droughts occurred in Shiraz station for 20-year statistical period (1983-2003) have been d...

This study was designed to provide valuable insight into the temporal patterns of rainfall in Benin City, Edo State, Nigeria using data from 1991 – 2020 (30 years) collected Nigerian Meteorological Agency (NIMET), airport station, City. The were assessed based on 10 years interval (decade) identified as decadal A (1991-2000), B (2001-2010) and C (2011-2020). analysed descriptively charts graphs...

The objective of this research was to analyse hydrological variability by conducting an intensive analysis extreme events, under dry and wet conditions. Drought conditions were assessed using the Standard Precipitation Index (SPI) Rainfall Anomaly (RAI), while Soil Conservation Service (SCS) method used simulate flooding at four stations. SPI results indicated that amount rainfall within catchm...
