The drought index (Keetch-Byram Drought Index, or KBDI for short) is created from both observed and calculated daily precipitation and surface temperatures.
This study first introduces a recent variation of Palmer's model, i.e. the standardized Palmer drought index (SPDI) as a hybrid of a Palmer drought index (PI) and a standardized drought index (SI).
We found that the area burned by managed fire peaked when the drought index was low and was reduced when the drought index was high.
Among the parameters considered are wind direction, speed and gusts, relative humidity, drought index and atmospheric stability.
Therefore, an annual drought index is defined by the ratio of actual to potential transpiration.
This might be attributed to the temperature effect on evapotranspiration and therefore on drought index.
Two resiliency metrics are developed and applied with the drought index time series.
A new drought index is introduced that explicitly considers both water supply and demand.
Drought Monitoring, from NOAA – the Palmer Drought Index, provides access to several drought monitoring products and historical records.
This study compares Percent of Normal (PN), Rainfall Decile based Drought Index (RDDI), statistical Z-Score, China-Z Index (CZI), Standardized Precipitation Index (SPI), and Effective Drought Index (EDI) to identify droughts in a semi-arid closed basin (Konya), Turkey.
The four drought indices are the Palmer Drought Severity Index (PDSI), the Reconnaissance Drought Index (RDI), the Standardized Precipitation Evapotranspiration Index (SPEI) and the Standardized Palmer Drought Index (SPDI).
