The butterfly effect

The weather in Catalonia depends on the atmospheric circulation in the middle of the North Atlantic, thousands of kilometers away. Any slight change in the initial conditions there will trigger a completely different result. This behavior, characteristic of chaotic systems, is known as the butterfly effect and is responsible for the unpredictablility of weather in the long term.
