This study aims to evaluate trends and structural shifts in monthly rainfall across 24 locations in Nigeria spanning 51 years (1960-2010). Utilizing the Mann–Kendall test statistic (MK) for trend identification and the cumulative sum method for detecting changes in structure, cyclic patterns, and random components within distributions, the analysis incorporated descriptive statistics, including the coefficient of variation, skewness, kurtosis, and the Jarque–Bera test with associated p-values. Descriptive statistics can behave unusually where abnormal rainfall patterns are common. Despite the nonparametric nature of MK, it occasionally yielded varying values and dissimilar trends between total annual rainfall and total seasonal rainfall, as well as between average annual rainfall and average seasonal rainfall, attributed to high variability. Consequently, a statistically significant trend in total rainfall amounts might not correspond to the trend in mean rainfall amounts. Notably, statistically significant trends may sometimes be accompanied by similar significant structural shifts at every location. However, such trends and shifts are generally more frequent in the northern arid regions, specifically between 9.14°N and 12.53°N. For instance, a statistically significant change in total annual rainfall of 11.15 mm/year was observed in Kano (12.03°N), accompanied by an increasing structural shift around the 40th year of analysis. Conversely, a total annual rainfall significant trend of -3.01 mm/year occurred at Jos (9.52°N), though it was not among the 9 locations with significant structural shifts. Analysis of this nature helps in tackling water-related issues and understanding atmospheric phenomena"},{"@xml:lang":"sl","#text":"Padavine – z različnimi časovnimi razponi – vplivajo na vremenske vzorce, življenjske razmere in okolje. Namen te raziskave je oceniti trende in strukturne premike v mesečni količini padavin na 24 lokacijah v Nigeriji v obdobju 51 let (1960–2010). Z uporabo Mann–Kendallove testne statistike (MK) za identifikacijo trenda in metode kumulativne vsote za odkrivanje sprememb v strukturi, cikličnih vzorcih in naključnih komponentah znotraj porazdelitev je analiza vključevala opisno statistiko, vključno s koeficientom variacije, asimetrijo, sploščenostjo in testom Jarque–Bera s pripadajočimi p-vrednostmi. Opisna statistika se obnaša nenavadno, kadar se pojavljajo posebnosti pri padavinah. Kljub neparametrični naravi MK je ta občasno dala različne vrednosti in različne trende med skupno količino letnih padavin in skupno količino sezonskih padavin, pa tudi med povprečno količino letnih padavin in povprečno količino sezonskih padavin, kar se pripisuje veliki variabilnosti. Posledično statistično pomemben trend skupnih količin padavin ne ustreza trendu srednjih količin padavin. Statistično pomembne trende lahko včasih spremljajo podobni pomembni strukturni premiki na vsaki lokaciji. Vendar so takšni trendi in premiki na splošno pogostejši v severnih sušnih regijah, zlasti med 9,14°N in 12,53°N. Statistično pomembna sprememba skupne letne količine padavin 11,15 mm je bila opažena v Kanu (12,03°N), ki jo je spremljal naraščajoči strukturni premik okoli 40. leta analize. Po drugi strani pa se je značilen trend povprečne letne količine padavin -3,01 mm/leto pojavil v Josu (9,52°N), čeprav ta ni bil med devetimi lokacijami z značilnimi strukturnimi premiki. Tovrstna analiza pomaga pri reševanju vprašanj, povezanih z vodo, in razumevanju atmosferskih pojavov"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-422T46X4","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-422T46X4"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-422T46X4/f54e3986-4eec-46a0-8acf-af265d7e5815/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by-nc-sa/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za gradbeništvo in geodezijo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-422T46X4/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-422T46X4"}}}}
