Persistence is an important characteristic of many complex systems in nature, related to how
long the system remains at a certain state before changing to a different one. The study of …

Agricultural drought affects the regional food security and thus understanding how
meteorological drought propagates to agricultural drought is crucial. This study examines …

Drought can negatively impact agricultural productivity, not only by reducing water
availability for plant growth, but also by disrupting soil microorganisms involved in nutrient …

Several studies have been conducted on droughts, precipitation, and temperature, whereas
none have addressed the underlying relationship between nonlinear dynamic properties …

Using multifractal detrended fluctuation analysis (MF-DFA), the pre-monsoon rainfall and
Indian summer monsoon rainfall (ISMR) from 1871 to 2016 are examined in this work for …

Abstract Detrended Fluctuation Analysis (DFA) is the most popular fractal analytical
technique used to evaluate the strength of long-range correlations in empirical time series in …

Tropical countries, like Nigeria, depend on rainfall for agriculture, power generation,
transportation and other economic activities. Drought will hinder the performance of these …

This study addresses into the critical issue of drought as a natural disaster, especially in
regions characterized by arid and semi-arid climates like Turkey. The primary aim of this …

We analyze trend and persistence in Standardized Precipitation Index (SPI) time series
derived from monthly rainfall data at 133 gauging stations in Pernambuco state, Brazil, using …

Affected by climate change and high‐intensity human activities, the precipitation series is
characterized by nonlinear complex fluctuations. In order to accurately quantify the …
