An old saying used for predicting the weather says, "Red sky at night, sailors' (水手) delight (高兴). Red sky in the morning, sailors take warning (警告)." Is the saying true? It turns out that it is. A red sky at sunset may mean that there are clear skies to the west, where the sun sets. A red sky at sunrise usually means that the clear weather has already passed, so storms might be coming.
Forecasting (预报) the weather has been practised for thousands of years. In the 5th century B.C., the Greeks sent out forecasts to sailors. They used signs in nature to forecast the weather. But today, *meteorologists* send detailed forecasts further in advance (提前). They use scientific skills to study weather conditions around the world and make forecasts. Pilots (飞行员), farmers and many other people depend on these forecasts. Luckily, now most of us can simply check on the smartphone or turn on the TV to find out what kind of weather is coming.
If you are looking for some signs of the weather, pay attention to nature. There are two basic rules that are used in weather forecasting: Weather generally moves from west to east, and low air pressure (压力) usually means coming rain or snow. So pay attention to the signs. If rainbows form in the west at sunrise, the sun is on the way. Smell the flowers—their smells are stronger in wet air. What are the ants doing? Are they moving to the higher ground? This could mean a drop in air pressure. Are the birds flying low or high? Falling air pressure may have an effect on birds' ears, so they fly low. And if the sky is red at sunset, you might plan a picnic for the next day!

有一句用来预测天气的古老谚语说道：“傍晚天红，水手高兴；清晨天红，水手警醒。”这句谚语是真的吗？事实证明它确实如此。日落时天空泛红可能意味着太阳落下的西方天空晴朗。日出时天空泛红通常意味着晴朗的天气已经过去，暴风雨可能即将来临。
预报天气的做法已经存在了数千年。在公元前5世纪，希腊人会向水手发布天气预报。他们利用自然界的迹象来预测天气。但如今，气象学家会提前更长时间发布详细的天气预报。他们运用科学手段研究世界各地的天气状况并做出预报。飞行员、农民和许多其他人都依赖这些预报。幸运的是，现在我们大多数人只需查看智能手机或打开电视就能知道即将到来的天气状况。
如果你在寻找一些天气迹象，那就留意大自然。天气预报中有两条基本规律：天气通常自西向东移动，低气压通常意味着即将下雨或下雪。所以留意这些迹象吧。如果日出时西方出现彩虹，晴天就要来了。闻一闻花朵——它们的气味在潮湿的空气中会更浓烈。蚂蚁在做什么？它们是不是搬到地势更高的地方了？这可能意味着气压下降。鸟儿是低飞还是高飞？气压下降可能会对鸟儿的耳朵产生影响，所以它们会低飞。如果日落时天空泛红，你或许可以计划第二天去野餐！
