俗话说：一层秋雨一层凉。入秋后天气正常情况下是逐渐变冷，不过有时候不期而至的暖潮也会让人恍惚间以为还是春天。“暖潮”的英语说法就是phantom spring。

　　Phantom spring refers to exceptionally warm fall or winter weather that causes plants or animals to act as though spring has arrived.

　　“暖潮”指的是秋冬出现的异常温暖的天气，使得植物或动物的表现好像春天到来了一样。

　　It's called a phantom spring where the plants start to die back but, because it's so mild, they start to give fresh growth. Meteorologists say that the warming climate means the phenomenon is likely to become common.

　　在暖潮到来时，本来已经开始枯萎的植株因为天气太暖和了，又长出了新叶。气象学家说，气候变暖意味着暖潮现象会变得更普遍。
