The strangest thing about Lhasa is the weather, probably because the city lies so high on the mountains. It can change suddenly in a very short time, and that has happened a few times in the past days. Yesterday is a good example. When we woke up at 8:00, it was cloudy but dry. Soon after, it started to rain a bit at around 10:00 am. After 20 minutes it became snowy, and it was freezing cold outside. Then at around 11:00, when we just finished our visit to Potala (布达拉宫), the snow stopped and the cloud became thin. An hour later, the temperature went up to 20 degrees and it became sunny! Later in the afternoon it became even warmer and we had drinks at an open air teahouse. At night after dinner when we wanted to take a taxi to the hotel, it suddenly was very cold again and it started raining again at 6:30. The whole day there was hardly any wind. But while waiting for the taxi at 7:00, the wind suddenly picked up. Today it’s sunny again, but windy. And the temperature is about 13 degrees. But the weather report that we received this morning said it would snow again.

In Britain the weather never gets too hot or too cold. There is no difference between summer and winter. Why is this?

Britain has a warm winter and a cool summer because it is an island country. In winter the sea is warmer than the land. The winds from the sea bring warm air to Britain. In summer the sea is cooler than the land. The winds from the sea bring cool air to Britain. The winds from the west blow over Britain all year. They blow from the southwest across the Atlantic Ocean (大西洋). They are wet winds. They bring rain to Britain all year, so Britain has a lot of rainy weather. The west of Britain is wetter than the east. The winds must blow across the high land in the west.
