The need for serially complete data may cause problems.

Historical Palmer Drought Indices

Palmer was tasked with developing a method to incorporate temperature and precipitation data with water balance information to identify droughts in crop-producing regions of the United States.

Erinc, Climatology and its Methods. Materials and methods actual hydrological conditions in a single number. Each of these drought indexes, their strengths and limitations are explained P briefly in the following section.

A serially complete record of temperature and precipitation data is required. Moreover, the presence of multiple time steps in drought indices make it harder to decide the best time step to show the drought conditions.

Proceedings of an Expert Group Meeting. The SPI is calculated by transforming the long-term mean precipitation for a given area in such a way that the mean equals zero.

Oladipo, A comparative performance analysis of three meteorological drought indices, J. Droughts coupled with water scarcity are becoming a serious threat to the economic growth, social cohesion and political stability.

Worldwide prevalence and duration of drought increases due to climate change and increasing water demands. The comparative results t — Mean temperature of the driest month show that PDSI index indicates more humid conditions than Erinc and De Martonne indices.

Several drought indices are used in drought assessment and monitoring based on rainfall data NDMC ; Hayes ; Wilhite et al. De Martonne aridity index classification in Central Anatolian Region. For example, the widely used Palmer Drought Severity 2. De Martonne method shows Ia — De martonne annual drought index small inconsistencies in the evaluations inside the water- T — Long years mean temperature sheds.

New York, Mc Graw-Hill The Erinc Index is generally consistent in the p — Total precipitation of the driest month evaluation of the watersheds. It is conceivably the most complex natural hazard.

No single definition or method of determining the onset, severity, and end of drought works under all circumstances or in all regions. It can affect large areas and may have serious impacts which depend on the severity, duration, and spatial extent of the precipitation deficit European Commission ARIMA models can be used as a forecasting tool of the future drought trends.

45, 被如下文章引用: TITLE: Characterizing, Monitoring and Forecasting of Drought in Jordan River Basin. The paper describes a new software package for automated estimation, display and analyses of various drought indices – continuous functions of precipitation that allow quantitative assessment of meteorological drought events to be made.

The Palmer drought index, sometimes called the Palmer drought severity index and often abbreviated PDSI, is a measurement of dryness based on recent precipitation and temperature.

It was developed by meteorologist Wayne Palmer, who first published his method in the paper Meteorological Drought [2] for the Office of Climatology of the U.S.
