12 December 2025, Czech Republic, Kozakov: People watch temperature inversion on Kozakov in Bohemian Paradise in the Czech Republic. Due to a temperature inversion (warmer air at higher altitudes), tourists can see further than 70 kilometres from Kozakov mountain. Stable high pressure causes cold, foggy weather in the lowlands and sunny weather on the mountains. Photo: Slavek Ruta/ZUMA Press Wire/dpa
