Research ArticleOpen accessEvery word in the titleAnalysis of the 16-20 February 2025 Damaging Heavy Rainfall in BotswanaOliver MosesHeavy rainfall that occurred from 16-20 February 2025 over most of Botswana caused, for example, flash flooding, fatalities, and widespread displacement, with the most severe impacts in the Gaborone-Mochudi region in the southeastern parts of the country. The drivers of this event are poorly understood; hence, this study analyses the rainfall characteristics using CHIRPS and station data. It also analyses … …American Journal of Applied Sciences, Vol. 23, Issue 1 · 24 Aug 2026 · 1,111 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEfficient Rainfall Forecasting Using Sequential Momentum-Based Artificial Neural Networks for Urban Flood ManagementSherin K K, G. SuganthiUrban floods cause severe disruption in densely populated cities and damage essential public infrastructure. Rapid urbanization and weak drainage systems further increase the risk during heavy rainfall. Accurate short-term rainfall forecasting is required to support early warning and reduce losses. This research focuses on improving rainfall prediction accuracy using an Artificial Neural Network trained with a new optimizer named Sequential … …Journal of Computer Science, Vol. 22, Issue 4 · 9 Apr 2026 · 1,539 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparative Analysis of Five Decomposition Techniques for Monthly Rainfall Time Series from 1991 to 2020 in Guinea (West Africa)Noukpo Médard Agbazo, Oumar Keita, Alpha Oumar Baldé et al.The selection of an optimal time series decomposition’ technique is crucial for enhancing rainfall prediction by using sophisticated methods as deep learning hybrid approaches. This study evaluates the effectiveness of five times series decomposition techniques in analyzing monthly rainfall datasets across Guinea geographical regions (Lower-Guinea (Boké, Conakry, Kindia), Middle-Guinea (Labé, Mamou), Upper-Guinea (Faranah, Kankan) and Forest-Guinea (Nzérékoré)) and identifies the … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 27 Jan 2026 · 3,040 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Selected Low-Risk Insecticides and Rainfall Rate on Bemisia tabaci Population and Pepper Yellow Leaf Curl Indonesia Virus Incidence on ChiliAndi Nasruddin, Iftitah Kartika Amaliah, Nurul Arfiani et al.Pepper Yellow Leaf Curl Indonesia Virus (PepYLCIV) is a damaging chili disease in Indonesia. Chili growers depend on synthetic insecticides to control the disease by suppressing its vector population, Bemisia tabaci Genn. This study assessed the efficacy of several low-risk insecticides in suppressing the B. tabaci population and PepYLCIV incidence during the dry and rainy seasons. Treatments consisted of different … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 26 Jan 2024 · 5,826 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTrend Analysis of Some Indices of Extreme Rainfall EventsOlumuyiwa Idowu Ojo, Femi Dakaye, Masengo Francois IlungaClimate change events results in increased temperature, changing rainfall patterns, floods and droughts. These will not only affect human but also affect how environment responds to the events. In this study, analyses of the trend change of 10 indices of Extreme Rainfall Events were carried in three stations of middle belt of Nigeria namely Jos, Lokoja and Makurdi using the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 1 Jan 2018 · 7,865 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleThe Rainfall Factor of Climate Change Effects on the Agricultural Environment: A ReviewOlumuyiwa Idowu Ojo, Masengo Francois IlungaThe study of the climatic elements is vital for sustainable development of agriculture of a region. Particularly, rainfall temporal analyses for trends, fluctuations and periodicities are necessary as such can indirectly furnish the status of an environment. A trend may be quite instructive for different segments of the human and natural systems. Extreme weather events that can lead to events … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 26 Oct 2017 · 8,335 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInteractions of Aerosol Optical Depth and Cloud Parameters with Rainfall and the Validation of Satellite Based Rainfall ObservationsMd Monirul Islam, Md Mainul Islam Mamun, Md Zahidul Islam, Mumnunul KeramatAerosol-cloud interactions influence the global precipitation patterns that influence significantly the Earth's climate system. Anthropogenic aerosols alter the clouds and their optical properties. The present study has investigated the Aerosol Optical Depth (AOD), cloud parameters and rainfall interactions for three different monsoon periods (2008-2010) and also compared the satellite rainfall with ground based observations, by using MODIS and TRMM datasets. … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 24 Jun 2017 · 7,751 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModeling of Rainfall Characteristics for Monitoring of the Extreme Rainfall Event in Makassar CityWahidah Sanusi, Usman Mulbar, Hendra Jaya et al.Flooding is a common problem that occurs in some regions of Indonesia, including Makassar city. In the planning of flood control, rainfall variables are very necessary as the frequency, intensity and duration of rainfall. The relationship of these variables can be expressed in a curve Intensity-Duration-Frequency (IDF). The objectives of this study are to identify the best fitting distribution of … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 10 Apr 2017 · 7,797 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTIME SERIES MODELING OF MONTHLY RAINFALL IN ARID AREAS: CASE STUDY FOR SAUDI ARABIANidhal SaadaStochastic techniques are essential in planning and management of water resources systems especially in arid and semi-arid areas where water is scarce. The forecasting of future events requires identifying proper stochastic models to be used in this process. For this purpose, a Periodic ARMA (PARMA) model and a temporal disaggregation models were used in this study to investigate weather they … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 3 May 2014 · 7,204 accessesView PDFCite
