The Standardized Precipitation Index (SPI) is a standardized measure of the variability precipitation and widely used for drought assessment around world. In general, probability distribution to calculate SPI in many studies Gamma. addition, monthly time-scale applied assess based on atmospheric moisture supply over medium-to-long term. However, distributions other than Gamma are various region...

The Mediterranean region is an area particularly susceptible to water scarcity and drought. In this work, drought has been analyzed in Italy using multiple timescales of the standardized precipitation index (SPI) evaluated from Integrated Multi-satellitE Retrievals for Global Precipitation Measurement product 2000 2020. particular, characteristics (severity, duration, intensity) have estimated ...

This paper examines past drought and assesses future drought scenarios for the Arkansas Red River Basin using two common drought indexes, the Standardized Precipitation Index (SPI) and Palmer Drought Severity Index (PDSI). Historical climate data within the 1900–2009 time frame were used to derive the past drought index estimates. The projected climate data under two greenhouse gas emission sce...

Drought is a slow-onset phenomenon that evolves over season or even years. affects people more than any other natural disaster due to its widespread and significant negative impacts. Population growth associated water demand add further stress on resources, especially in periods of drought. indices represent single value resulting from processing considerable amount data. These provide short me...

Drought is a natural disaster. Because a significant impact on the agricultural and economy sector, it affects the lives of local residents. With Using of the remote sensing, drought can be studied through its effects on plants and agriculture resulting in more accurate and effective results found for modeling drought. In this study, the efficiency of agricultural drought indicators for estimat...

Three main sea surface temperature (SST) oscillations in the Atlantic and Pacific oceans have shown to play a key role modulating rainfall variability over northern Mexico. Nevertheless, only few studies explored these teleconnections under climate classification approach. In this study, effects of Decadal Oscillation (PDO), Oceanic El Niño Index (ONI) Multidecadal (AMO), precipitation dry semi...

• Asymmetric effects of precipitation anomalies on beech growth were detected with forest inventories. More extreme had disproportionally large diameter growth. Growth reductions in dry extremes 3 times greater than increases wet extremes. Stand basal area, the social status a tree and species diversity significantly affect In temperate forests, precipitation-productivity relationships have usu...

Weather-pattern, or weather-type, classifications are a valuable tool in many applications as they characterize the broad-scale atmospheric circulation over a given region. This study analyses the aspects of regional UK precipitation and meteorological drought climatology with respect to a new set of objectively defined weather patterns. These new patterns are currently being used by the Met Of...

     Drought is a disaster phenomenon especially in arid and semi-arid areas. Vegetation and its production play a main role in the social and economic issues in every country. In this study, Standardized Precipitation Index (SPI) and Normalized Difference Vegetation Index (NDVI) data have been used to monitor drought and the vegetation condition in Sonqor Abad in, Kermanshah province.  Meteoro...
