The climate in Britain is usually described as cool, temperate and humid.British people say: "Other countries have a climate, in England we have weather."The weather in Britain changes very quickly. One day may be fine and the next day may be wet. The morning may be warm and the evening may be cool. Therefore it is natural for the people to use the comparison "as changeable as the weather" of a person who often changes his mood or opinion about something. The weather is the favourite topic of conversation in Britain. When two Englishmen are introduced to each other, if they can't think of any thing else to talk about, they talk about weather. When two people meet in the street they will often say something about weather as they pass, just to show their friendliness.Every daily paper publishes a weather forecast. Both the radio and television give the weather forecast several times each day.The English also say that they have three variants of weather: when it rains in the morning, when it rains in the afternoon or when in rains all day long. Sometimes it rains so heavily that they say "It's raining cats and dogs".Rainfall is more or less even throughout the year.
