Inland, it decreases to around 130 cm (50 inch) over most of central Nigeria and only 50 cm (20 inch) in the extreme north. Rainfall and temperature data were collected from Ikeja, Benin, Ibadan, Ilorin, Kaduna and Kano, in Nigeria. The Sahel climate or tropical dry climate, is the predominant climate type in the northern part of Nigeria. check climate change (Pat-Mbano and Alaka , 2012), and this certainly is exposing its citizenry to enormous risks and vulnerabilities associated with climate change and variability. The rainy season in the northern part of Nigeria last for only three to four months (June–September).

The warmest month is May with an average maximum … Rainfall amount, pattern, duration each year, have a serious impact on the condition of biodiversity, forest and wildlife in the study area. However, a comprehensive research hypothesis was formulated for the study. This study examines the length of the growing season in Nigeria using the daily rainfall data of Ikeja, Ondo, Ilorin, Kaduna and Kano. 220 Rising temperatures, more erratic rainfall (causing both droughts and floods) and rising sea levels along Nigeria’s southern coast have contributed to large-scale changes in the agricultural Rainfall data for one hundred years (1914-2013) of Aminu Kano International Airport synoptic meteorological station obtained from Nigerian Meteorological Agency Table 1. Nigeria whose sources of livelihood is rainfall dependent [7]. One of them is the sea equatorial air, which in the summer brings wet winds from the coast, and then a low pressure zone appears over the desert, and the other is a continental tropical one, and it is transported from the Sahara by a dusty dry … Here are some average weather facts we collected from our historical climate data: On average, the temperatures are always high. His analysis indicated that in the first decade of 1971-1980 anomalies between -0.2 and -1.6 were predominant, spending (Federal Government of Nigeria, 2013). Rainfall variation is projected to continue to increase. Cumulative percentage mean rainfall was employed to generate the rainfall onset and retreat dates series, while the method of stepwise multiple regression analysis was used to construct the required … The durations and intensities of rainfall have increased, producing large runoffs and flooding in many places in Nigeria (Enete IC, 2014). This study makes use of the annual rainfall data of forty years (1978-2017) for South-South, Nigeria which was collected from the Annual rainfall amounts decrease in a gradient moving south to Annual rainfall totals are lower compared to the southern and central part of Nigeria.

ODEKUNLE* Department of Geography, Obafemi Awolowo University, Ile-Ife, Nigeria Received 15 May 2003 Revised 8 December 2003 Accepted 16 December 2003 ABSTRACT This study examines the length of the growing season in Nigeria using the daily rainfall … There was a sharp difference between … Climate change is increasingly becoming a serious challenge to Nigeria's socioeconomic development. Minimum temperature (Tmin), maximum temperature (Tmax) and evaporation recorded increases of 2.47, 1.37 and 28.37 %, respectively, but a reduction of 19.58 % in rainfall … Lower rainfall in the north, for example, reduces the availability of trees and … locations in Nigeria, in terms of Latitude, Longitude and Altitude (m), are presented in Table 2. Rainfall is the most important natural factor that determines the agricultural production in Nigeria, particularly in the South western part of Nigeria. It captures the impact of climate change on men and women in characteristic disaster areas of the South-Eastern and North- The variability of rainfall and the pattern of extreme high or low precipitation are very important for agriculture as well as the economy of the state. Obot et al. Our study revealed periodicities of 2.3 and 2.25 years in wet and dry seasons and periodicities of 2 to 5 years on seasonal and annual timescales. Given the current precarious situation in Northern Nigeria rainfall is highly unpredictable, where the importance of analysis of rainfall variation in drought characterization can-not be over emphasized [8] [9]. The widespread poverty, the fact that Nigeria’s economy depend on climate-sensitive sectors mainly rain fed agriculture, poor infrastructure, heavy disease burdens, high dependence on and unsustainable exploitation of natural resources, and conflicts render the country especially vulnerable to impacts of drought. solar radiation and rainfall. Rainfall in nigeria pdf Rainfall in Nigeria is characterized by both latitudinal and longitudinal variations. The basic objective of this investigation is the determination of the spatial distribution of rainfall in Plateau State. 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. 2.1 Documentation of Nigeria’s Vulnerability to Climate Change 16 2.2 Nigeria’s Primary Crops 17 3.1 Sources and Quality of Data Used in the Analysis 28 The rainfall data used consists of data from the year 2007 to 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. 2219 Figure 1.

The paper seeks to examine the perception and awareness of climate change in Osogbo metropolis. This study examined the extent of climate change in Kano through rainfall data analysis. contrast between the SST locations and rainfall stations in Nigeria, surface location of ITD and land surface temperature of rainfall stations in Nigeria. Nigeria is also highly vulnerable to the effects of climate change, which is already having direct impacts across the Sahel region. In the south, annual average temperatures range from 17–37°C and in the north from 12–45°C.
