This present study analyzes the rainfall trends and temperature patterns in the zone in order to determine the current climatic trends. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation. Epochal patterns of Indian summer monsoon rainfall It is well known that Indian summer monsoon rainfall displays multi-decadal variations in which there is a clustering of wet or dry anomalies (Pant and Kumar, 1997). I am happy to note that just like in 2016, when the national HDR focused on ‘Human Security and Human Development in Nigeria’ and underlined the imperative of Human Security across the board, the focus of this Report on Nigeria’s North East is equally timely. It decreases from the south to the north, the rainfall comes late and not evenly spread across the rainy season and consequently has adverse effect on agricultural activities (Iloeje, 1981).

The underlying cause of most droughts can be related to changing weather patterns such as low rainfall, reduced cloud cover and greater evaporation rates In the central area, where the rainy season is longer, the sunshine hours decrease for a longer period. On the Annual and Seasonal Pattern of Rainfall Fluctuations in Sub-Saharan West Africa. This belief widely held in some circles does not really follow this pattern due to other climatic factors. In northern Nigeria, the peak monthly mean rainfall amount of 91 mm was observed in August and rainfall amount was very low in January (0.0 mm), February (0.0 mm), March (0.0 mm) and December (0.0 mm). Rainfall Pattern in Nigeria It is a common believe that all water on the earth comes from the rain and stored as surface water such as rivers, ponds, oasis, or underground water as spring and water table etc. Based on weather reports collected during 2005–2015. rainfall years are in both the modelling and the validation periods.

This seasonal variation of rainfall is the focus of this research. The rainfall pattern has also enhanced wind erosion/desertification, soil erosion and coastal flooding in the north, east and coastal areas of Nigeria respectively. Generally, man’s comfortability depends mostly on the weather condition which largely depends on radiation from the sun and rainfall .Over the years, different kinds of radiation are considered.
