【摘要】 为了研究气象干旱指数对西南干旱的监测状况,本文利用西南地区90个气象站台的观测资料,基于一种改进的综合气象干旱指数的计算方法,分析了西南地区近40年的干旱气候特征。本文主要是从干旱发生频率、干旱发生等级的特征、干旱日数的演变特征以及四个季节的特征三大方面进行分析。更多还原

【Abstract】 In order to study meteorological drought index for the Southwest drought monitoring the situation, we use observations Southwest 90 weather stations stations, an improved method of calculation based on integrated meteorological drought index, analyzes the Southwest arid climate characteristics for nearly 40 years. This article is mainly occurring from drought frequency, level of features drought, drought in the evolution of the number of features and characteristics of the four days of the season were analyzed three aspects.更多还原
