Abstract:

Published Article<br>The objective of this study was to characterize meteorological droughts in the Central Region of South Africa, Modder River Basin, C52A quaternary catchment using two popular drought indices: Standardized Precipitation Index (SPI) and Standardized Precipitation-Evapotranspiration Index (SPEI) and to compare the two indices. Drought events were characterized based on their frequency, duration, magnitude and intensity. The indices were computed for the time-scales that are important for planning and management of water resources, i.e. 3-, 6- and 12-month time-scales. The bas

Abstract:

This research is focused on space-time analysis of droughts, based on rainfall data. In order to obtain time series of droughts, the Standardized Precipitation Index (SPI), a rainfall based drought index was used. The spatial analysis of the phenomenon was based on the regional analysis with L-moments. For the time series studies, the continuous wavelet transform was used. This technique shows up as an alternative to Fourier analysis, to identify periodicities in time series and to find variations of these frequencies over time. Also was sought to investigate possible influences of El Niño Sou

A seca que assola o norte de Minas Gerais é um desencadeante de severos impactos socioambientais. Mudanças na distribuição das precipitações, ou mesmo a redução no volume de chuvas é fator suficiente para a desorganização da atividade econômica regional. Neste contexto, este trabalho analisou a distribuição espaço-temporal da seca/estiagem no norte de Minas Gerais, entre 2003 a 2014. A metodologia consistiu na elaboração de série temporal de anomalia padronizada de NDWI utilizando imagens de reflectância MOD13Q1/MODIS.

Abstract:

Anthropogenic activities including urbanization, rapid industrialization, deforestation and burning of fossil fuels are broadly agreed on as primary causes for ongoing climate change. Scientists agree that climate change over the next century will continue to impact water resources with serious implications including storm surge flooding and a sea level rise projected for North America. To date, the majority of climate change studies conducted across the globe have been for large-sized watersheds; more attention is required to assess the impact of climate change on smaller watersheds, which ca

Abstract:

Meteorological drought indices are commonly calculated from climatic stations that have long-term historical data and then converted to a regular grid using spatial interpolation methods. The gridded drought indices are mapped to aid decision making by policy makers and the general public. This study analyzes the spatial performance of interpolation methods for meteorological drought indices in the United States based on data from the Co-operative Observer Network (COOP) and United States Historical Climatology Network (USHCN) for different months, climatic regions and years.

Drought is a global and recurrent natural phenomenon, the inevitable consequence of meteorological variability. This natural hazard brings about devastating effects because water is one of the most fundamental commodities for human survival, and a lack of water can result in varying consequences, from mere inconvenience to life threatening instances. Drought cannot be prevented but its effects can be mitigated through the design of appropriate water resource infrastructure and management strategies. The goal of this thesis is to model the spatial and temporal characteristics of drought occurre

Abstract:

The South African Weather Service (SAWS) has reported a decline in the number of rainfall observation stations due to inadequate financial resources to meet maintenance costs. This reduction in rainfall stations complicates the calculation of the rainfall-based Standardised Precipitation Index (SPI) drought index mainly owing to the sparse distribution of these stations and the high variability of rainfall. The SPI is used to inform short-term drought mitigation and relief decisions. This study investigates the determination of a spatially improved Standardised Precipitation Index (SPI) using
