Thanks Ian, trouble is again this is a "secondhand" source being a weather news and views type site and not run by the Italian Met Office, with no link/origin for the data. However, that they do not note the 48.5 °C reading is probably a good indication of its unofficial and unreliable nature. Still they probably felt the need to compile this because it's not easily found (if at all) on the Meteoam site (possibly one has to scrutinise the data for each individual station). The curious thing is a "curiosità" page at http://clima.meteoam.it/curiosita.php which gives world figures, but try finding anything for Italy alone...
Not at all. Catenanuova readings is 100% OFFICIAL AND CORRECT.
Dozens of nearby stations gave similar temperatures during the brutal heat wave of August 1999.
It is a AUTOMATIC REAL TIME station OF SIAS CIRCUIT: therefore it is an official station.
You should know how Italy works in Meteorology: Aeronautica Militare DOESNt MANTAIN ANY station at the moment, but they gave the maintenance of their main circuit to the company ENAV.
This short list of stations is a very small percentage of all italian stations , because most of italian stations are mantained by the local regional meteorological stations.Therefore there are several nets of stations and their data should be checked into these databases.
SIAS is Sicily have very modern stations equipped by automatic stations with modern filters, for example Palermo Observatory has currently a station worth 30000 euros , of better quality of most stations around the world.
In the brutal 1999 heat wave several sicilian station recorded 48C.
That was not the first time 48C was recorded in Sicily, first time was in July 1962 with 48.0C at Paterno (near Catenanuova), than Plano Falzone also recorded 48.2C, and so on...
The "piana di Catania" zone is by far the hottest in Europe during these circustances and in summer maxima average is around 40C much hotter than the zone around Athens.
In August 1999 a pure 30C at 850hpa grabbed Sicily with sirocco winds crossed the central mountains and redescended hot and dry for downslope effect ,compressed hot air lied into the Catania plais where the vulcanic soil further helps strong irradiation.
That was the strongest heat wave ever in Europe, 47C was also recorded in the region of Calabria at Locri.
Catenanuova holds the European highest reliable temperature ever without any doubt.
Moreover i had Catenanuova station checked by a friend of mine who went there 3 years ago....it is at almost 1.9m above the ground,and equipment and screen modern and well mantained.
It's hard to believe that Italy considers this 48.5 official since as I said before my understanding is that Aeronautica Militare in Italy is Greece's equivelant EMY (HNMS) which are the sole organisations within respective countries to provide ''officials''
If this was indeed a reliable temperature it would defenetelly have passed the WMO scrutiny and Italy would consider it official.Why has not the World Meteorological Organisation accepted this as Europe's highest and accepts the 48.0 in Athens?Do u happen to know?Are u Italian maybe?
Also what are the other areas that recorded 48 in 1999 in Sicily?I dont remember any such example and I have checked a lot for the highest temp in Europe.Which were the exact stations that recorded 48 in Sicily and how is this data verifiable.Please let us know its very intruiging
