Discussion of 'Meteorological Drought Quantification with Standardized Precipitation Anomaly Index for the Regions with Strongly Seasonal and Periodic Precipitation' by Kironmala Chanda and Rajib Maity

摘要

In the original paper, Chanda and Maity proposed a new meteorological drought index, called standardized precipitation anomaly index (SPAI), mimicking the general methodology of the most popular drought index, called standardized precipitation index (SPI).
