The analysis of climatic variability/weather trends (past and future) in eastern U.P.

Author(s): Ajit Singh, AK Singh, UP Sahai, SP Singh and Smarpal Singh
Abstract: Underneath these trends is that of decadal scale variability in the Pacific basin at least induced by the Interdecadal Pacific Oscillation (IPO), which causes decadal changes in climate averages. On interannnual timescales El Ni˜no/Southern Oscillation (ENSO) causes much variability throughout many tropical and subtropical regions and some mid-latitude areas. During the course of the 21st century global-average surface temperatures are very likely to increase by 2 to 4.5 OC as greenhouse gas concentrations in the atmosphere increase. By concentrating on changes in climate means, the full impacts of climate change on biological and human systems are probably being seriously underestimated. Here, we briefly review the possible impacts of changes in climate variability and the frequency of extreme events on biological and food systems, with a focus on the developing world. We present new analysis that tentatively links increases in climate variability with increasing food insecurity in the future. Climatic variability & weather trend analysis were made for past and future based on the historical data results reveal that. Future rainfall scenario of eastern U.P. Showed much varying trends in monthly rainfall and was observed that in eastern U.P. rainfall will increase during south west monsoon period up to 2080 but the month of August will face sharp decline in rainfall. Projected trends in temperature and rainfall over eastern U.P. reveal that rainfall will not significantly affect the yield of rice crop as compared to temperature. The rate of increase of maximum temperature in eastern U.P. will be higher during 2050 to 2080 (2-4 0C) as compared to 2020-2050 (1-2 0C).
