厄尔尼诺/拉尼娜事件对内蒙古自治区气候的影响
Effects of El Nino/La Nina Events on Climate in Inner Mongolia Autonomous Region
摘要
Abstract
Based on the meteorological data collected in Inner Mongolia Autonomous Region during the past 50 years,we analyzed the characteristics of climate change in Inner Mongolia Autonomous Region since 1961 and attempted to establish the relationship between El Nino/La Nina events and the variables including annual precipitation,temperature and natural disasters.The results showed that compared to the normal years,annual precipitation of the El Nino years was 31.45 mm and that of La Nina years was 14.69 mm less by average,indicating a significant influence by the ENSO events on the regional climate.In contrast,annual temperature increased by an average of 0.12 ℃ in the El Nino years,and by an average of 0.22 ℃ than in the La Nina years,indicating that the ENSO events caused significant warming in the study area.Generally speaking,ENSO events increased the possibility of drought disaster,and moreover,the El Nino years had even higher possibility of drought than the La Nina years.Consequently,El Nino/La Nina events were often unfavorable for the agricultural and animal husbandry production of Inner Mongolia Autonomous Region.关键词
