Droughts are difficult to detect and monitor. Drought indices, most commonly the Palmer
Drought Severity Index (PDSI), have been used with limited success as operational drought …

In the Rocky Mountain region between central Montana and central New Mexico,
sedimentologically isolated nonmarine basins were produced by basement deformation during the …

The development of new tools that provide timely, detailed-spatial-resolution drought information
is essential for improving drought preparedness and response. This paper presents a …

The Standardized Precipitation Evapotranspiration Index ( SPEI ) was computed based on
the monthly precipitation and air temperature values at 609 locations over China during the …

ABSTRACT. Hypercalcemia and hypercalciuria in sarcoidosis are thought to result from the
endogenous overproduction of an active vitamin D metabolite. We employed primary …

The Palmer Drought Severity Index (PDSI) has been used for more than 30 years to quantify
the long-term drought conditions for a given location and time. However, a common critique …

Recent droughts in the United States have highlighted the nation’s current and increasing
vulnerability to this natural hazard. Drought-related impacts are also becoming more complex, …

The Standardized Precipitation Index (SPI) was developed to detect drought and wet periods
at different time scales, an important characteristic that is not accomplished with typical …

Severe drought is a recurring problem for the United States, as illustrated by widespread
economic, social, and environmental impacts. Recent drought episodes and the widespread …

The effect of the length of record on the standardized precipitation index (SPI) calculation
was investigated by examining correlation coefficients, the index of agreement, and the …
