“…There have been many previous studies about drought indices; the study to investigate spatial and temporal characteristics as well as the trend of meteorological drought using a single drought index such as SPI or PDSI [7,8,9], the comparison between two drought indices in order to detect or analyse drought for the better performance of drought monitoring [10,11], in addition, the evaluation of several drought indices in order to get the best performance results [12,13,14].…”

Occurrence of drought is due to climate variability and climate change. Drought affected on agriculture, economic, social and environment. The suitable technique in detecting and monitoring drought events can provide useful information for prevention and mitigation planning from their impacts. The study objective was to investigate the change of rainfall and temperate as well as find out the appropriate drought index and its trend for the Northern part of Thailand. These drought indices were calculated by using meteorological data during 1951-2020 of 10 stations comparing with historical drought records between January and May during 2011-2016 in the same areas. The drought indices consisted of Standardized Precipitation Index (SPI), Deciles index and Moisture Available index (MAI) at 1-, 3- and 6-month timescales and Palmer Drought Severity Index (PDSI). It was found that PDSI was the most appropriate index. The Mann-Kendal test was used to investigate the trend of rainfall, temperature and PDSI. The results showed an increasing of temperature. There was no trend of drought intensity for long-term (40 years) periods but was in 4 stations for short-term (20 years) periods. The PDSI can be used for drought monitoring and predicting in advance by using numerical weather prediction products.

In the Egirdir Lake Basin (Turkey), the six drought indices (i.e., SPI, PNI, DI, CZI, RAI and ZSI methods) were calculated for the three stations at 57 years between 1965 and 2022 on a 1-month and 1-year time scale. A positive correlation was determined between the drought index values calculated by the SPI, RAI, ZSI and CZI methods for three meteorological stations, even if the calculation method remains conceptually very different. Extremely dry periods and compatible results were determined in similar years according to all drought analysis methods for 1-year time scale at all stations. The RAI index gave the highest overall drought value (− 4.5) over the 1-year time scale compared to other indexes. In the analyzes of all drought methods, a very high correlation was determined for each station on a 1-year time scale. The correlation between the drought indices determined by different methods increased depending on the time scale. According to the drought analysis, it has been determined that there are dry periods for long periods, especially in recent years. It has been determined that this situation is compatible with the level drops in Egirdir Lake.
