Long-Term Trends and Its Best Functional Form Estimation of Yearly Maximum and Minimum Temperatures at Cotonou City by Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise Method

Atmospheric and Climate Sciences 2022年第1期12卷 31-42页

The understanding of the long-term trend in climatic variables is necessary for the climate change impacts studies and for modeling several processes in environmental engineering. However, for climatic variables, long-term trend is usually unknown whether there is a trend component and, if so, the functional form of this trend is also unknown. In this context, a conventional strategy consists to assume randomly the shape of the local trends in the time series. For example, the polynomial forms with random order are arbitrarily chosen as the shape of the trend without any previous justification. This study aims to 1) estimate the real long-term nonlinear trend and the changing rate of the yearly high temperature among the daily minimum (YHTaDMinT) and maximum temperatures (YHTaDMaxT) observed at Cotonou city, 2) find out for these real trend and trend increment, the best polynomial trend model among four trend models (linear, quadratic, third-order and fourth-order polynomial function). For both time series, the results show that YHTaDMinT and YHTaDMaxT time series are characterized by nonlinear and monotonically increasing trend. The trend increments present different phases in their nonmonotone variations. Among the four trend estimations models, the trend obtained by third-order and fourth-order polynomial functions exhibits a close pattern with the real long-term nonlinear trend given by the Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (ICEEMDAN). But, the fourth-order polynomial function is optimal, therefore, it can be used as the funct

Dynamics and Diurnal Variations of Surface Radiation Budget over Agricultural Crops Located in Sudanian Climate

引用

Atmospheric and Climate Sciences 2013年第1期3卷 121-131页

作者： Basile Kounouhéwa Ossénatou Mamadou Gabin Koto N’gobi Cossi Norbert Awanou Laboratoire de Physique du Rayonnement (L.P.R) Faculté des Sciences et Techniques (FAST) Université d’Abomey-Calavi Cotonou Bénin

Energy exchange between land and atmosphere are important in climatic processes. In this paper, the seasonal dynamics and diurnal variations of surface radiation components of agricultural crops are investigated. One year data are used to emphasize the separate contribution of each radiation balance component. From the energy budget equation and FAO empirical model, we compare the clear sky solar radiation and the incoming short wave radiation in order to highlight aerosols and water vapor role in the studied area. The analysis show two important results: 1) The relevance of the short wave radiation in the net radiation budget especially in the wet season and 2) The variations of the long wave radiation were small. Analyses provide an understanding of net radiation seasonal variations in the northern part of Benin.

Analysis and Predictability of Dry Spell Lengths Observed in Synoptic Stations of Benin Republic (West Africa)

American Journal of Climate Change 2021年第4期10卷 597-618页

作者： Médard Noukpo Agbazo Joseph Adébiyi Adéchinan Gabin Koto N'gobi Joseph Bessou International Chair in Mathematical Physics and Applications (ICMPA-UNESCO Chair) Université d’Abomey-Calavi Abomey-Calavi Bénin Laboratoire de Physique du Rayonnement (LPR) Université d’Abomey-Calavi Abomey-Calavi Bénin Département de Physique Faculté des Sciences et Techniques Université Nationale des Sciences Technologies Ingénierie et Mathématiques (UNSTIM) Abomey Bénin Agence Nationale de la Météorologie du Bénin (METEO BENIN) Cotonou Bénin

The complex behavior and predictability of the Dry Spell Lengths (DSL) series obtained in Benin synoptic stations, from 1951 to 2010 are analyzed in this paper using a fractal approach. The synoptic stations are located in Cotonou, Bohicon, Save (subequatorial climate), and Parakou, Natitingou, Kandi (Sudanian climate). The DSLs are computed by considering four thresholds level, R0 = {1.0, 1.5, 2.0 and 5.0} mm/day. The fractal trace is estimated for dry spell density by the mean of the “Dry Spell Spell” (DSS) n-index. The rescaled range method is used to determine the predictability of DSL. By analyzing the DSS, results show that low DSS n-index values (n-index 0.4) occur preferentially in the southern part. Therefore, during 1951-2010, the Sudanian region presents frequent wet spells, alternated with short dry spells than in the subequatorial one. However, a high degree of long dry spell persistence, followed by short dry events is observed in the subequatorial region than in the Sudanian one. The longest DSL is observed in the subequatorial region, especially in Cotonou. Except for the Kandi station, the DSLs series obtained at synoptic stations are characterized by persistence. Therefore, autoregressive processes could be applied to the DSL series. Generally, the physical process governing dry spells observed at Save, Natitingou, and Bohicon are consistently predictable than the process governing the stations of the Cotonou and Parakou. However, at Kandi station, the DSL process approximates the usual Brownian motion, and it is, therefore, unpredictable or difficult to predict.

Newborn Umbilical Cord Care in Parakou in 2013: Practices and Risks

引用

Open Journal of Pediatrics 2016年第1期6卷 124-135页

作者： Joseph Agossou Marcelline Hounnou-d’Almeïda Julien Didier Adédémy Alphonse Noudamadjo Doué Yasmine Gounou N’gobi Blaise Ayivi Department of Mother and Child Faculty of Medicine University of Parakou Parakou Benin Department of Mother and Child Faculty of Health Sciences University of Aboomey-Calavi Cotonou Benin

Objective: The objective was to study umbilical care practices and risks in Parakou (North Benin). Patients and method: It was a cross-sectional and descriptive study carried out within a community from June 1 to August 31, 2013. It focused on all the infants born at the maternity of Parakou Health Center and their mothers. Results: Two hundred and ten newborns were included i.e. 101 boys and 109 girls. In 80.9% of cases, inappropriate substances had been applied to umbilical cord. Umbilical cord care quality was adjudged as poor, acceptable and good in 58.6%, 31.9% and 9.5% of cases respectively. A bacterial umbilical infection had been noted in 59.5% of newborns. Only 4.8% had sterile umbilical wound. The commonest bacteria were: Staphylococcus aureus (58.1%), Staphylococcus saprophiticus (53.3%), Escherichia coli (44.8%) and Pseudomonas aeruginosa (14.3%). The factors associated with umbilical infection were: low educational status of mother (p = 0.026), low-income occupation of mother (p = 0.021), customary practices to accelerate umbilical cord fall off (p = 0.007), short time to cord falling off lower than 6 days (p = 0.015). Conclusion: Umbilical cord care involves high risk for bacterial infection in our context. Strong actions must be taken within the community in order to reduce that risk.
