摘要

本研究对印度东部地区 2021-2050 年和 2051-2080 年两个未来气候期的旱季(1 月至 5 月)和雨季(6 月至 9 月)与 1980-2012 年当前气候期进行了趋势分析和偏差校正。研究采用了 2.6、4.5、6.0 和 8.5 等不同的代表性浓度路径(RCPs)来评估研究地区的未来趋势。结果表明,与 2051-2080 年期间的基线温度相比,由于辐射力(4-8.5 W/m2)的增加,RCP 的增加会使所有地区的温度(最高温度和最低温度)升高。此外,偏差校正后的降雨量与基线相比呈下降趋势,而两个时间片(2021-2050 年和 2051-2080 年)的 RCP 值显示,与旱季相比,雨季的降雨量分散程度较低。

Bias Correction and Trend Analysis of Temperature and Rainfall in Eastern India

Bias Correction and Trend Analysis of Temperature and Rainfall in Eastern India

In this study trend analysis and bias correction have been done for dry (January–May) and wet (June–September) seasons under two future climate period 2021–2050 and 2051–2080 with respect to the current climate period 1980–2012 in Eastern India. The different representative concentration pathways (RCPs) of 2.6, 4.5, 6.0, and 8.5 were used to assess the future trend of the study area. Results indicate that the increasing RCP increases temperature (maximum and minimum) in all regions due to higher radiative forces (4–8.5 W/m2) with respect to the baseline temperature during the period 2051–2080. Further, the bias-corrected rainfall has a declined trend with respect to baseline, and RCP’s values for both the time slices (2021–2050 and 2051–2080) showed less scattering in the amount of rainfall for the wet season in comparison to the dry season.
