Prototype of a drought monitoring and forecastingsystem for the Tuscany region

A system for drought monitoring and medium–long time forecasting in the Tuscany region (central Italy) is briefly introduced, which is based on ground and satellite data (1km spatial resolution and 16-day temporal resolution). It is also shown how information about current conditions and the future evolution of a drought event is periodically delivered on the LaMMA Consortium website, in collaboration with the Institute […]

A Counting Process Approach for Trend Assessment of Drought Condition

This paper discusses some methodological aspects of the historical analysis of drought, particularly the trend assessment. The Standardized Evapotranspiration Index (SPEI) is widely used as a measure of drought condition. Since different SPEI thresholds allow classifying the risk into moderate, severe, and extreme, the drought occurrence becomes a counting process. In this framework, would a […]
