摘要

利用各种干旱指数来监测和检测干旱及其可能的影响。水文气候参数，包括降雨量、温度和土壤湿度，在识别干旱现象方面很重要。在本研究中，采用了10个显著指数（SPI、SPEI、scPDSI、CZI、MCZI、RAI、RDI、DI、PNI和ZI）来监测土耳其杰伊汉盆地的干旱事件。利用八个气象站对这些指标的适用性及其与历史干旱相对应的表现进行了检验。除了scPDSI，其他指标在1个月的时间尺度上表现出很强的相关性，在3、6、9和12个月的不同时间尺度上，只有SPI、SPEI和RDI之间的相关性很高。虽然SPI、SPEI和RDI在1个月的时间尺度上在感知干旱严重程度类别方面表现出很强的相关性，但在较长的时间尺度下，SPEI与其他两个指数的相关性较低。

Drought monitoring in Ceyhan Basin, Turkey

Various drought indices are utilized to monitor and detect drought and its probable effects. Hydro-climate parameters, including rainfall, temperature and soil moisture, are important in identifying drought phenomena. In this study, 10 notable indices (SPI, SPEI, scPDSI, CZI, MCZI, RAI, RDI, DI, PNI and ZI) have been employed to monitor drought events in the Ceyhan Basin, Turkey. The applicability of these indices and their performances corresponding to historical droughts were examined by employing eight meteorological stations. Apart from the scPDSI, other indices have shown a strong correlation for 1-month time scale, and at different time scales of 3, 6, 9 and 12 months, only the correlation between the SPI, SPEI and RDI was observed to be high. While the SPI, SPEI and RDI have demonstrated a strong correlation in perceiving drought severity categories for 1-month time scale, for longer time scales the correlation of the SPEI with the other two indices was low.
