rainfall trends and variability

Climate change in particular constitute a major menace to rainfall patterns which will directly or indirectly affects the ecosystems. According to the Department of Ecology 2015, state of Washington, climate change leads to rising levels of carbon dioxide and other heat-trapping gases in the atmosphere have warmed the Earth and are causing wide-ranging impacts, including rising sea levels; melting snow and ice; more extreme heat events, fires and drought; and more extreme storms, rainfall and floods. In addition, a change in the usual timing of rains or temperatures can affect when plants bloom and set fruit, when insects hatch or when streams are their fullest. MOTIVATION Long-term Trends and Variability of Rainfall Extremes in the Philippines Marcelino Q. Villafuerte II,1,2 Jun Matsumoto,1,3 Ikumi Akasaka1 and Hisayuki Kubota3 1 Dept. It is for this reason that this study was carried out to examine the nature and extent to which climate change has affected rainfall trends and variability in Jos. Managing climate risk in agriculture requires a proper understanding of climatic conditions, regional and global climatic drivers, as well as major agricultural activities at the particular location of interest. search your topic. They showed that there has been a progressive early retreat of rainfall over the whole country, and consistent with this pattern, they reported a significant decline of rainfall frequency in September and October which, respectively coincide with the end of the rainy season in the northern and central parts of the country. Rainfall patterns usually have spatial and temporal variability. This presentation is focused on the OpenMOOC project. The tropical rainfall regime experienced in Ibadan is bi-modal, convectional and follows the apparent movement of the sun while both length of rainy season and the yearly total rainfall, decreases with increasing distance from the equator. Variations in rainfall trends are still burning issues in the research frontiers. are highly sensitive to climate variability and climate change because of their close links to the natural environment. Studies have shown that climate variability is as a result of changing rainfall pattern (Goswami et al., 2006; Adger et al., 2003). Our analysis is focused on describing spatial and temporal variability of rainfall in . Crops and animals derived their water resources largely from rainfall. Global warming and climate change have been identified as the major factors influencing rainfall trend and variability. Crops and animals derived their water resources largely from rainfall. » ABSTRACT . Such changes will have dire consequences in various socio-economic sectors such as agriculture firms. Climate change analysis requires datasets that not only cover a long span of time, but are also homogeneous through time.

Ibadan’s wet season runs from March through October, though August sees somewhat of a lull in precipitation. As a result of the large inter-annual variability of rainfall, it often results in climate hazards, especially floods and severe and droughts with their devastating effects on food production and associated calamities and sufferings (Oladipo, 1993; Okorie, 2003; Adejuwon, 2004). Gregory, 1983 reported that changing spatial pattern of annual and rainy season monthly rainfall indicated a long run of dry years for sub-Saharan West Africa during the 1940s. The movement of the monsoon trough or inter-tropical convergence zone, brings rainy seasons to savannah climes (Laux et al, 2010, Mudita et al 2008). In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of the mountains. Found insideFor the very first time, this book provides updated, integrated and organized, theoretical and methodological information on regional climate change and the associated environmental and socio-economic impacts on a regional scale. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of the mountains. This can affect historically synchronized pollination of crops, food for migrating birds, spawning of fish, water supplies for drinking and irrigation, forest health, and more (Todd et al 2001; Dominic et al 2004; Adams & Faure 1997). Rainfall patterns usually have temporal and spatial variability. This book gives a coherent development of the current understanding of the fluid dynamics of the middle latitude atmosphere. Therefore study is relevant because it will assist researchers to understand the future consequences of rainfall variation due to climate change.
