The Kraków Uprising of February 1846 was an attempt, led by Polish insurgents such as Jan Tyssowski and Edward Dembowski, to incite a fight for national independence. The uprising was centered on the city of Kraków, the capital of a small state of Free City of Kraków.
It was directed at the powers that partitioned Poland, in particular, the nearby Austrian Empire.
The uprising lasted about nine days, and ended with Austrian victory.Źródło: https://en.wikipedia.org/wiki/Krak%C3%B3w_Uprising
Often they visit the nationwide research centers located in city, such as the National Center for Science and the Branch of the Polish Academy of Sciences.
In addition, they can learn the rules of research by Cracow's research units.
Kraków has an oceanic climate (Cfb) according to the Köppen climate classification system, one of the easternmost localities in Europe to do so.
A mere 100 km (62 mi) north-east of Kraków (east of Tarnów, and north of Kielce), the January mean dips below ?3 °C (27 °F) and thus becomes continental (Dfb) in nature.
The Kraków climate is also influenced by its far inland position, with significant temperature differences between seasons.
The average annual temperature is 8.7 °C (48 °F).
In summer temperatures often exceed 25 °C (77 °F), and even 30 °C (86 °F), while winter drops to ?5 °C (23 °F) at night and about 0 °C (32 °F) at day; during very cold nights the temperature can drop to ?15 °C (5 °F).
Since Kraków lies near the Tatra Mountains, there are often occurrences of halny blowing (a foehn wind), causing temperatures to rise rapidly, and even in winter reach up to 20 °C (68 °F).Źródło: https://en.wikipedia.org/wiki/Krak%C3%B3w#Climate.
