TREBISACCE, CALABRIA, ITALY - 2023/03/04: A sudden, rapidly changing cloud front appears to form a vortex over the houses of Trebisacce, in Calabria, southern Italy. The sudden change in climatic conditions is due to a clash between cold air coming from the North and warm air coming from the sea and from the South.
