Here you can query, map, compare, chart and summarize key climate The Sahel climate or tropical dry climate, is the predominant climate type in the northern part of Nigeria. Examples of implications of high rainfall variability and low probability of receiving certain given threshold amounts of rainfall at different phenological stages of crop developments, are given. As reported by the FAO, agriculture remains the foundation of the Nigerian economy, despite the presence of oil in the country. Change in rainfall pattern is one of the observed and projected impacts of climate change across the Sudano-Sahelian region of Nigeria. An Assessment of Rainfall Distribution Pattern and Climate Extremes in Southern Nigeria : Choosing a probability distribution to represent the precipitation depth at various durations has long been a topic of interest in climatology and hydrology. The panels at the bottom are the violin plots and show the distribution of rainfall in each state. The climate in the Northern part of the country is different from the climate in Southern Nigeria. This study aims at studying the peak daily rainfall distribution characteristics in Nigeria, by using different statistical analyses such as Gumbel, Log-Gumbel, Normal, Log-Normal, Pearson and Log-Pearson distributions. 2018). Rainfall distribution in Nigeria between 1901 little increase in temperature between 1961 and 2018, temperature within the same period. 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. Such rainfall distribution in Nigeria has caused the appearance of the vegetation zones described below: 1. Eludoyin et al. In this post, we will tell you about the months of the rainy season in Nigeria. (2009) studied monthly rainfall distribution in Nigeria between 1985-1994 and 1995-2004 and noticed some fluctuations in most months within the decades. The aim of this paper is to examine the recent rainfall trends and variability in Sudano-Sahelian region of Nigeria from 1986-2015.

Analysis of temporal and spatial variability of total column ozone over West Africa using daily TOMS measurements. Average total May-October rainfall in Nigeria based on the 1981-2015 historical record (mm) Source: FEWS NET/USGS CHIRPS . Conversely, rainfall variabilities are higher on the lowlands of the State than on the high Plateau. The good news is that the increased rains witnessed across Nigeria in 2018 are actually good to the farms. 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. Monthly rainfall pattern over Nigeria takes its conventional mono-modal (Savanna and Sahel) and bi-modal (Guinea) distribution as shown in Fig. 3 (2020): FUDMA Journal of Sciences - Vol 4, No. 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. 10-year running mean, linear trend line equation, second order polynomial, Cramers test and students t-test were used to achieve this aim. Global Economic 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. The data was retrieved from the archives of the Nigerian Meteorological Agency in Lagos. These examples serve to substantiate the need for supplementary irrigation facilities in the Slate. According to Kppen and Geiger, this climate is classified as Aw. But The summers here have a good deal of rainfall, while the winters have very little. Furthermore, rainfall variabilities are higher at the beginning and at the cessation of rainfalls than in the middle of the rainy season. This paper examined rainfall temporal trend inter-annual and spatial distribution and the implication of mean annual rainfall on maize and rice yield in North Central Geopolitical Region of Nigeria. (2009) studied monthly rainfall distribution in Nigeria between 1985-1994 and 1995-2004 and noticed some fluctuations in most months within the decades. Effect of Climate Change on Agricultural Productivity in Nigeria: A Co-integration Model Approach. 1 (2020): FUDMA Journal of Sciences - Vol 4, No. Inland, it decreases to around 130 cm (50 inch) over most of central Nigeria and only 50 cm (20 inch) in the extreme north. 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 19701990 to 19% in 19912000, to 21% in 20012010. The climate is tropical in Ibadan. 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 high Plateau in particular. Since this territory is located in an over-inflated zone, a peculiar high-mountain vegetation has formed here. The projected trends revealed that there is going to be decreasing of temperature for Billiri station in SGS and an increasing trend of rainfall for Gombe station in NGS for the coming decades. Nigeria has many different climates, but is dominated by Aw.
