Feasibility Analysis and Improvement of Comprehensive Meteorological Drought Index in Chongzuo
For the “unreasonably worse drought” showed by the comprehensive meteorological drought index, this paper proposes a non-linear unequal weight calculation method and an improved comprehensive meteorological drought index (CI<sub>43</sub>), and analyzes the applicability of CI<sub>4...

| description | For the “unreasonably worse drought” showed by the comprehensive meteorological drought index, this paper proposes a non-linear unequal weight calculation method and an improved comprehensive meteorological drought index (CI<sub>43</sub>), and analyzes the applicability of CI<sub>43</sub> in drought monitoring and evaluation based on historical data at 12 metrological stations in Chongzuo from 1961 to 2015. The results showed that: ① The monitoring results by CI and CI<sub>43</sub> are relatively close on the drought monitoring process. The improved CI<sub>43</sub> avoids effectively the unreasonably worse drought showed by CI; ② The corrected drought grade standard of CI<sub>43</sub> avoids the overestimating or underestimating the drought grade, so the evaluation results by CI<sub>43</sub> are more scientific and reasonable; ③ The monitoring results by CI<sub>43</sub> on the occurrence, development and relief of drought are more consistent with the actual drought. Therefore, we can concluded that the CI<sub>43</sub> is more suitable for drought monitoring and evaluation in Chongzuo. |
