The other location in the world with an almost identical climate is British Colombia, in Canada. However, in Britain we are protected from these low temperatures by the influence of the sea which stays at about the same temperature all the year. The Gulf Stream, a vast river of water originating in the Gulf of Mexico, flows across the Atlantic and warms the air which blows across our shores. This keeps Britain warm in winter but cooler in summer than countries away from the sea. In fact, the westerly winds blowing across the Atlantic dominate the British climate.
Fronts develop in which warm, moist Atlantic air is pushed up over cooler air.
The moisture in the warm air condenses into clouds and it often rains, especially on high land in the West of the country. Protected a little from the westerly winds, and a little more influenced by continental weather, the eastern side of the Britain is a little drier and colder in winter and a little warmer in summer, especially in the South. The climate varies from place to place. We all know that it is warmer on the south-facing side of a hill in the Northern Hemisphere because it catches more sunlight. If a strong, cold wind is blowing it is warmer to shelter behind a hedge or wall.
