This indicator measures drought conditions of U.S. lands. Average Drought Conditions in the Contiguous 48 States, – This chart shows annual values of the Palmer Drought Severity Index, averaged over the entire area of the contiguous 48 states. Positive values represent wetter-than-average conditions, while negative values represent. underwent correlation-based principal component analysis (PCA), and the first principal component was deseasonalized to arrive at a single ADI value for each month. ADI time series were compared against the Palmer Drought Severity Index (PDSI) to describe two important droughts in California, the – and – events, from a.
Soil moisture data is calibrated to a homogeneous climate zone. PDSI has been widely used to recognize long-term agricultural drought and hydrological drought, and to identify the abnormality of a particular drought in a region. Short-term droughts are calculated by the Palmer Z . A method for weekly monitoring of the Palmer Drought Index (PDI) by using four parallel month-long calculation chains in rotation (“ROLLING” method) was tested for the Kansas Northwest Climate Division and the South Carolina Southern Climate Division and compared to two other methods, a modified version of the Climate Prediction Center’s weekly Palmer Drought Index monitoring method Cited by:

It was developed by meteorologist Wayne Palmer, who first published his method in the paper Meteorological Drought for the Office of Climatology of the U.S. Weather Bureau. Based on the Palmer Drought Index, severe to extreme drought affected about 4 percent of the contiguous United States as of the end of Julyan increase of about 3 percent from last month.
About 9 percent of the contiguous U.S. fell in the severely to extremely wet categories.; About 9 percent of the contiguous U.S. fell in the moderate to extreme drought categories (based on the. Monthly maps of drought conditions in the contiguous U.S.
as measured by the Palmer Drought Severity Index, Palmer Hydrological Drought Index, Palmer Modified Drought Index, and Palmer Z-Index (Palmer, ) are provided for January —January Animations of any set of monthly maps for any period desired can be viewed by selecting the. The operational Palmer Drought Index (PDI) attempts to measure the duration and intensity of the long-term drought-inducing circulation patterns.
Long-term drought is cumulative, so the intensity of drought during the current month is dependent on the current weather patterns plus the cumulative patterns of previous months. The Palmer Drought Severity Index (PDSI) uses readily available temperature and precipitation data to estimate relative dryness.
It is a standardized index that generally spans (dry) to +10 (wet). Maps of operational agencies like NOAA typically show a range of -4 to +4, but more extreme values are possible.
DROUGHT INDICES – SPI • Different time scales reflect the impact of drought on the availability of the different water resources • Mckee et al. ()* define a criteria for a drought event for any of the time scales • Drought event occurs any time the SPI is continuously negative and reaches an intensity of File Size: 2MB.
The Palmer Drought Index (PDI) and Palmer Hydrological Drought Index (PHDI) shown on this web page represent a way of estimating the monthly PDI and PHDI on an operational weekly basis.
If the date of the maps is before the end of the month, then observed temperature and precipitation through the date of the map are combined with HOME > Monitoring and Data > U.S.

Palmer Drought Severity Index is a measure of dryness where negative values represent drought and positive values reflect excess rain. Palmer Z-Index. Time Series Box. Function: generate a time series of select variables from through the most recent complete month. The equation for the index was empirically derived from the monthly temperature and precipitation scenarios of 13 instances of extreme drought in western Kansas and central Iowa and by assigning an index value of -4 for these cases.
Conversely, a +4 represents extremely wet conditions. The index is able to identify the major drought events during the latter part of the twentieth century and shows good agreement with the time series of U.S.
