Sažetak
Severe cold weather with a lot of snow and strong wind on Croatian coastline at the beginning of February 2012 inspired many to recollect the winter of 1956. Here we present the weather events of winter 1956 described using the measured data from the meteorological stations and NCEP re-analysis fields. The vertical sounding measurements were operational at the time in Split. Winter 1956 was cold across Europe, the channels were frozen even as far south as Toulouse and is listed as one of the exceptionally cold winters in Europe in 20th century. The winter Olympics in Cortina d'Ampezzo (26th January to 5th February) experienced lack of snow at the alpine skiing events so that Italian army transported large amounts of snow. January 1956 was relatively warm, cyclones moved over Baltic and wind over Adriatic and much of the Mediterranean was from south and southeast. The high pressure over Russia spreads to Scandinavia and UK, while pressure remains low above Mediterannean. The string of cyclones support strong northeasterly wind over Croatia with severe bura on Croatian coastline. Temperatures first decrease on eastern part of Balkan peninsula (Bulgaria and Greece) on 26th January due to cyclone above Aegean sea. Temperatures fall below 0°C on northern Adriatic on 31st January 1956 due to Genoa cyclone and the cols spreads south as the cyclone moves over Tyrhenian and Ionian Seas. Second cyclone developed above western Mediterranean on 9th February 1956 and brought more cold weather, severe wind and snow to Croatian Islands. The minimum average diurnal temperatures during February 1956 were below zero on all stations except Palagruza, reaching -12.9 in Senj, -9.2 in Rijeka, -8.8 in Crikvenica and -7.9 in Sibenik. The minimum temperatures were considerably lower, -16.6 in Senj, -12.8 in Rijeka, -13.1 in Crikvenica and -11.0 in Sibenik, even Palagruza measured -0.5C. All these stations are on the coast. The average diurnal wind speed reached 10 Bf (26.4 m/s) in Senj, 9.3 (23.8 m/s) in Split and 8Bf (18.9 m/s) in Sibenik. Hvar Island measured 6cm of snow with minimum temperature of -3.6. Snow height was limited by strong bura wind that prevented accumulation of large amounts of snow. The inland of Croatia, then part of former Yugoslavia, also suffered from extreme cold weather, Yugoslavian army bombed the Danube river to release it from ice that accumulated and caused flooding upstream.
