“…Minimum precipitation near the coastline is less than 600 mm east of Pollino and less than 700 mm east of Sila. These minima are a consequence of the shielding effect of the mountains because Mediterranean storms usually impinge Calabria from west to east (Federico et al, 2008(Federico et al, , 2009.…”

“…The two sub-regions are useful to assess, indirectly, if large-scale patterns play a role in the type of storms affecting the region. In a previous study (Federico et al, 2008) it was shown that: a) western Calabria is more exposed to storms originating in the lee of the Alps; and b) eastern Calabria is more exposed to African storms (originating in the lee of Atlas and propagating toward the central Mediterranean). So, correlations between large-scale patterns and precipitation over Calabrian sub-regions indirectly suggest a larger incidence of particular types of storms.…”

Abstract. This brief communication introduces a new quality-controlled precipitation database for Calabria, shows the precipitation trend for the period considered, and correlates daily rainfall with some common teleconnection patterns. The database consists of daily accumulated precipitation collected by 61 rain gauges from 1 January 1970 to 31 December 2006.The 37-year trend in yearly rainfall shows a decrease of 4.7 mm/y, with a 17% reduction in the yearly mean value.The correlation of the daily rainfall with large-scale patterns shows that the Mediterranean Oscillation Index (MOI a/c) is a useful predictor of daily precipitation over Calabria.

“…In such conditions breeze circulations develop along the coasts and inland, representing the dominant circulation. Winter cyclones and synoptic-scale circulations dominate in the cold season (form November to March; Bolle, 2012;Federico et al, 2008;Hurrell, 1995).…”

Three-model ensemble wind prediction in southern Italy

et al. 2016

Abstract. Quality of wind prediction is of great importance since a good wind forecast allows the prediction of available wind power, improving the penetration of renewable energies into the energy market. Here, a 1-year (1 December 2012 to 30 November 2013) three-model ensemble (TME) experiment for wind prediction is considered. The models employed, run operationally at National Research Council -Institute of Atmospheric Sciences and Climate (CNR-ISAC), are RAMS (Regional Atmospheric Modelling System), BOLAM (BOlogna Limited Area Model), and MOLOCH (MOdello LOCale in H coordinates). The area considered for the study is southern Italy and the measurements used for the forecast verification are those of the GTS (Global Telecommunication System). Comparison with observations is made every 3 h up to 48 h of forecast lead time.Results show that the three-model ensemble outperforms the forecast of each individual model. The RMSE improvement compared to the best model is between 22 and 30 %, depending on the season. It is also shown that the three-model ensemble outperforms the IFS (Integrated Forecasting System) of the ECMWF (European Centre for Medium-Range Weather Forecast) for the surface wind forecasts. Notably, the three-model ensemble forecast performs better than each unbiased model, showing the added value of the ensemble technique. Finally, the sensitivity of the three-model ensemble RMSE to the length of the training period is analysed.

“…Mugnai et al: Outcomes of the 9th EGU Plinius Conference on Mediterranean Storms Houssos et al (2008) study the main synoptic conditions associated with extreme rainfall events in Greece in the period 1970-2002, clustering the different atmospheric circulation patterns. Federico et al (2008) use numerical modelling and ground-based rainfall measurements for the period 1999-2007 to study the atmospheric circulation patterns associated with heavy rainfall events in Calabria, southern Italy. Michaelides et al (2008) analyse a catalogue of hailstorm events in Cyprus during the period 1996-2005, and group the events in two clusters based on synoptic, dynamic and thermodynamic characteristics.…”
