Forecasting SPEI and SPI Drought Indices Using the Integrated Artificial Neural Networks
The presented paper compares forecast of drought indices based on two different models of artificial neural networks. The first model is based on feedforward multilayer perceptron, sANN, and the second one is the integrated neural network model, hANN. The analyzed drought indices are the standardized precipitation index (SPI) and the standardized precipitation evaporation index (SPEI) and were ...
متن کاملRegionalization Analysis of SPI and SPEI Drought Indices for Karoon Basin
The current study was conducted to compute SPI and SPET drought indices due to their multi-scale concept and their ability to analyze different time-scales for selected meteorological stations in Karoon Basin. Regionalization of SPI and SPEI Drought indices based on clustering analysis was another aim of this study for hydrological homogenizing. Accordingly, to run test through data and determi...
متن کاملTemporal-Spatial Variation of Drought Indicated by SPI and SPEI in Ningxia Hui Autonomous Region, China
The Ningxia Hui Autonomous Region of China (Ningxia) is an important food production area in northwest China severely affected by drought. The Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) were calculated based on monthly meteorological data to explore climate change and variation in drought intensity, duration, frequency, and spatial exte...
متن کاملcomparison of spi and spei indices to meteorological drought assessment using r programming (case study: kurdistan province)
drought indices are commonly used to quantify and assess drought characteristics. the standardized precipitation index (spi), and recently introduced standardized precipitation-evapotranspiration index (spei) are considered as universal meteorological drought indices which allow comparisons of drought conditions across different climate regions. the spi captures anomalies in precipitation, wher...
متن کاملDetermining the most appropriate probability distribution function for calculate and compare the SPEI and SPI drought index in Tehran
Introduction: The study of drought as a natural phenomenon that affects the lives of most people is very important. According to researchers in the field of drought, rainfall, temperature, evaporation, wind and relative humidity have been shown to play an important role in drought. The low variety of data required and the simplicity of calculating the SPI index led to its widespread use. The ef...
