ПЕРЕВОД ТЕКСТА
Like most of north western Europe, the climate in the United Kingdom is defined as a temperate oceanic climate, consisting of four distinct seasons of fairly equal length - spring, summer, autumn and winter. As this island country is surrounded by seas, it has a varied climate which is hard to predict, meaning that the weather often changes from day to day. It can be sunny one day and rainy the next. In general, the UK has warm summers and cool winters.
Even though the rainfall in U.K. is high, the humidity in this country is not as high as might be expected. This is mostly because there are no extremely hot summer temperatures. The average annual humidity goes from 70% in southern England, which is the lowest, to 92% in the central and northern parts of the UK.
As the country with the most unpredictable day to day weather, there is no general clothing norm for different seasons. The top recommendation for anyone visiting Great Britain would definitely be layering. The smartest way to cope with this uncertain weather is to prepare both short-sleeved and long-sleeved T-shirts, jumpers and a coat. This way, you can easily put them together in different ways and take them off, if needed. Raincoats and umbrellas are useful items to carry in this rainy country.
The United Kingdom has no serious weather or environmental risks. This part of the globe is not known for hurricanes, tsunamis or earthquakes like in eastern Asia or North America. There are no active volcanoes in United Kingdom either. In general, Europe doesn't have any huge environmental risks. The only country that has some active volcanoes is Iceland, which is situated in the middle of two tectonic plates.
