Why is the climate in Britain changeable?

Britain is located between 50 and 60 degrees north latitude, farther north than Heilongjiang Province in China, but the climate is much milder. It can be said that there is no cold in winter and no heat in summer. This mild climate is first attributed to the tropical Gulf Stream. This warm current is hundreds of kilometers wide. Flowing to the northwest coast of Europe, it was renamed the Atlantic Warm Current, which brought a mild and humid maritime climate to Britain. Take London as an example, rivers and lakes rarely freeze in winter, and the average temperature of 1 month is above 4 degrees (Celsius); In summer, the weather is quite cool. The average temperature in July is only 17 degrees, so you often need to add a sweater in the morning and evening. The annual rainfall is about 600 mm, which is not much, but it is evenly distributed. As far as the whole country is concerned, the average temperature in 1 month is about 4 to 7 degrees, and in July it is 13 to 17 degrees. The annual rainfall in the northwest mountainous area exceeds 1000 mm, while it is between 600 mm and 700 mm in the southeast. Britain is foggy, with thin haze on sunny days in summer; Winter is often foggy, like rain but not rain, and if smoke is not smoke, this is mainly caused by the humidity of the island country. As for the dense fog that used to be common in London, it is not entirely a natural phenomenon. Due to the emphasis on environmental protection, the dense fog there has been greatly reduced.

The island has a mild climate, but the weather is changeable. British people often say: "There is climate abroad, but only weather in Britain" to show that the weather here is unpredictable. Indeed, it is not uncommon to see sunny, cloudy and rainy days in one day. This weather makes people very cautious. Seeing an Englishman wearing a raincoat and carrying an umbrella when he goes out on a sunny morning, foreigners may find it ridiculous, but he will soon regret his "ridiculousness". The changeable weather also provides people with frequent topics, and even the most taciturn people in Britain like to talk about the weather.

Affected by high latitude, the length of day and night in Britain is particularly obvious. In winter, the days are short and the nights are long. Before 3 pm, the sky was already dark. In summer, on the other hand, the days are long and the nights are short, and it begins to get dark at night 10. Generally speaking, summer is the best time to visit Britain. In summer, the days are long, the activity time is long, the temperature is moderate, the weather is refreshing, and people are full of energy. Although there is rain this season, it is generally discontinuous, which will affect the trip.

Generally speaking, the weather characteristics in major areas of Britain are as follows:

Northern England: The temperature is lower than that in the south.

Northeast England: the coldest region

Southern England: the region with the best climate.

Southeast England: High temperature in summer, low temperature in winter, and large temperature difference.

East England: A region with less rainfall.

West England: The region with the most rainfall.
