Why British weather is so unpredictable

Transcript

Why is the weather in Britain so famously unpredictable? Look, in a single day it can rain, then fog, suddenly sunshine and right after that hail. Oh yeah, and of course, the wind. In some parts of the UK and Ireland, there can be up to 250 rainy days a year. So it might seem like this is the rainiest place on Earth. I swear it is, actually, it's not. In fact, more than 70 countries receive more annual precipitation than the UK. And first place usually goes to Colombia, due to its tropical climate, proximity to the Pacific Ocean, and mountainous terrain. Put Britain's weather is something else. That's because this place is literally a battlefield of weather, where several air masses collide at once. From the west comes the official sponsor of rain, the Gulf Stream. A warm ocean current fills the air with moisture, while western winds carry it straight toward the British Isles. Because they sit so far north, cold Arctic air moves straight in from the north. From the south rises warm air. And from the east comes drier air from mainland Europe. So who's winning at that moment? That's the weather you get.
