International Journal of Research and Innovation in Social Science (IJRISS) |Volume II, Issue III, March 2018|ISSN 2454-6186 www.rsisinternational.org Page 15 An Assessment of Rainfall Distribution Pattern and Climate Extremes in Southern Nigeria Ibeabuchi U, Egbu, A. U and Kalu, A. O. Modelling distribution of rainfall in South West Nigeria is examined. Thus, this study aimed at addressing this gap by describing the epidemiology … Nigeria. Working off-campus? The data was retrieved from the archives of the Nigerian Meteorological Agency in Lagos. The raining season in Nigeria does not start in the same months in different parts of Nigeria. The black rectangles represent the 25% and 75% quantiles and the white dot is the median. Monthly rainfall pattern over Nigeria takes its conventional mono-modal (Savanna and Sahel) and bi-modal (Guinea) distribution as shown in Fig. Temperature in Nigeria averaged 26.74 celsius from 1856 until 2013, reaching an all time high of 31.83 celsius in April of 2010 and a record low of 22.30 celsius in January of 1983. But when the noisiness of the data was reduced by using appropriate statistics for extreme distributions and by considering trends in total rainfall accumulation, they were able to show that the proportion of annual rainfall associated with extreme rainfall has increased from 17% in 1970–1990 to 19% in 1991–2000, to 21% in 2001–2010. Also, on July 15, the Nigeria Meterological Agency, NiMet, warned that many parts of the country were likely to experience flooding due to a shift in rainfall pattern caused by climate change. The results show that the greatest amounts of rainfall are obtained in the southern and western parts of the State and on the southern and western margins of … The cholera outbreak in 2018 in Nigeria reaffirms its public health threat to the country. As reported by the FAO, agriculture remains the foundation of the Nigerian economy, despite the presence of oil in the country. The study concludes that there is a significant increase of temperature in all the zones and there is no statistical trend of rainfall in SS. Average rainfall along the coast varies from about 180 cm (70 in) in the west to about 430 cm (170 inch) in certain parts of the east. Regional variations in fluctuations of seasonal rainfall over Nigeria. The good news is that the increased rains witnessed across Nigeria in 2018 are actually good to the farms. The need to have a quantitative means of modelling and predicting rainfall is very important for the purposes of Airplane movements, Agriculture, planning and policy formulation. Since this territory is located in an over-inflated zone, a peculiar high-mountain vegetation has formed here.

Inland, it decreases to around 130 cm (50 inch) over most of central Nigeria and only 50 cm (20 inch) in the extreme north.

In the southeast, the rainiest region, the decrease in rainfall in July and August doesn't occur: in Calabar, where 3,000 mm (120 in) of rain fall per year, rainfall remains around 400 mm (16 in) per month from June to September. Obot et al., (2011) studied the trends of rainfall in Abeokuta, Nigeria between 1981-2002. In their paper entitled „Analysis of rainfall distribution over Enugu during the little dry season (1990-2005)‟, Enete & Ebenebe (2009) showed that Aliyu Tambuwal Umar, Sani Abubakar Mashi, Mansur Matazu Bako, Investigation of Rainfall Characteristics in Sudano-Sahelian Region of Nigeria (1971–2006), Handbook of Climate Change Resilience, 10.1007/978-3-319-71025-9, (1-27), (2018). Projects & Operations ... Average Monthly Rainfall 1901 - 2009 (mm) The Climate Change Knowledge Portal is a hub of information, data and reports about climate change around the world. 11; The basic objective of this investigation is the determination of the spatial distribution of rainfall in Plateau State. The current trend will affect soil moisture, crop water requirement and subsequently lead to ecological change. Typical May-October rainfall in Nigeria ranges widely across the country. Typical May-October rainfall in Nigeria ranges widely across the country. The data was collected on 9 synoptic stations in the region. A. Yaro. A. S. Mmaduabuchi, 10-year running mean, linear trend line equation, second order polynomial, Cramer’s test and student’s t-test were used to achieve this aim. The aim of this study is to propose a model of Seasonal Autoregressive Integrated Moving Average (SARIMA) model to model and forecast the monthly frequency of the rainfall in Abuja, Nigeria for the period 1996 to 2018. 2Nigerian Meteorological Agency, Abuja, Nigeria. Rain water supply is the limiting factor to the growth and production of rice in Nigeria as reflected by geographical distribution of rice-growing areas over region of heavy rainfall. Table 3 lists the coefficients of determination (r 2) and regression equations of rainfall of moving averages, which depict the trend and inter-annual variations in rainfall in the various observation points in Nigeria between 1981 and 2009. Here you can query, map, compare, chart and summarize key climate … Conversely, rainfall variabilities are higher on the lowlands of the State than on the high Plateau. Also, on July 15, the Nigeria Meterological Agency, NiMet, warned that many parts of the country were likely to experience flooding due to a shift in rainfall pattern caused by climate change. About 1311 mm | … 20 stations having annual rainfall data of fifty-four (54) years were selected to perform frequency analysis. Temperature in Nigeria decreased to 25.14 celsius in August from 26.62 celsius in July of 2013.

(2014b) used the approach in its broader formulation, show-ing that the annual maxima distribution was heavy-tailed (positive value of the shape parameter of the GEV). (2009) studied monthly rainfall distribution in Nigeria between 1985-1994 and 1995-2004 and noticed some fluctuations in most months within the decades. Rainfall totals in central Nigeria varies from 1,100 mm (43.3 in) in the lowlands of the river Niger Benue trough to over 2,000 mm (78.7 in) along the south western escarpment of the Jos Plateau. Thus, this study aimed at addressing this gap by describing the epidemiology … Also, rainfall distribution in Nigeria differs from the South to the North.
