Drought Situation

- Invasi: in Sardegna e Sicilia il quadro è complessivamente migliorato. In Puglia e Basilicata la situazione rimane invece più eterogenea, con alcuni bacini in netta ripresa e altri che continuano a presentare condizioni di sofferenza.
- I grandi laghi del Nord chiudono il mese su livelli generalmente in linea o leggermente inferiori alla media. Nella prima parte di Giugno, dopo una fase di recupero registrata all’inizio, i livelli hanno ripreso a diminuire.
Previsioni per i prossimi mesi
Le previsioni stagionali dei maggiori centri europei indicano, per il trimestre Luglio-Settembre, una maggiore probabilità di temperature superiori alla norma su gran parte dell’Europa, con il segnale più marcato sul Mediterraneo centrale e sui settori continentali europei. Per quanto riguarda le precipitazioni, c’è una divisione geografica che vede, con una probabilità compresa tra il 40% e il 50%, condizioni più secche della norma sull’Europa settentrionale e orientale, inclusa la bassa Scandinavia e la Gran Bretagna, mentre sul Mediterraneo emerge un segnale opposto, con probabilità comprese tra il 40% e il 60% di condizioni più umide e piovose della norma.Drought WebGIS
A WebGIS application based on open source solutions customized to integrate different datasets and share maps and graphs of drought indices with researchers, decision-makers and other stakeholders.
Different functions allow to select sections of territory or visualize the trend of the indices in a specific pixel.
Maps and graphs can also be downloaded in png format.
Please Note: Due to the size of the images, it is possible to download sections of the vegetation indices smaller than the whole geographic window.
Please Note: due to problems concerning the Terra MODIS satellite, the TCI and VHI indices are available until the 9th of November 2022. They will be replaced soon with new products.
Drought Scan
The Drought Scan (DS) is an operational climate service for users with different profiles — technicians, researchers, irrigation consortia, and water authorities — who need a clear, consistent, and scalable assessment of drought conditions at the river-basin scale, using tools that are easy to use yet scientifically robust.

Drought
is a complex phenomenon
The challenge
Increasing environmental resilience
A Scientific Proactive approach
Technical support and timely information
A frequent phonomenon
After flooding, it is the second natural disaster that affects the population.
Long term impact
The impact on the environment and human activities can show up late and persist even after the end of the drought event.
High variability
Its intensity and spatial extent are extremely variable.
A creeping phenomenon
With respect to other natural extreme events, drought is characterised by a slow and often difficult to define onset and a long-lasting evolution.
Drought Observatory: the reason why

- direct climate-based indices.
- indirect vegetation-based indices
Spatial Data Infrastructure
SOA | OGC | PostgreSQL
A Service-Oriented Architecture (SOA) based on Open Geospatial Consortium (OGC) standards. Database-centred architecture, with PostgreSQL DataBase Management System.
Innovative Approach
The geographic data flows (from the download of remote sensing and climatic data to the storage of final indices) and all the related geoprocessing functions are integrated in a single environment.
Advanced Statistical Procedures
The integration of the PL/R (R Procedural Language) wrapper into the procedural language of PostgreSQL (PL/pgSQL) allowed the creation of advanced statistical procedures using R engine.
