Wrocław is the fourth-most populous and fifth-largest city in Poland in terms of area. It is situated in three mesoregions: two plains and a glacial valley, and between the hills to the north and the Sudetes to the south. The Oder River and its four tributaries flow through the city. The proximity of the Sudetes causes phenotypic phenomena in Wrocław, where strong, dry winds increase temperatures. This occurs especially in winter – in 1990, this phenomenon caused temperatures to rise by as much as 20 degrees Celsius.
