Imagine a perfect day: the weather is good and everything seems fine. When, suddenly, your mobile phone loses its signa l, the television has no programs, and you can’t get online with your computer.
What has happened? These are just the types of problems a solar storm(太阳风 暴)might cause. You may not think of storms as putting our society in danger. But today, a solar storm is as serious as other bad events, such as earthquakes.
A solar storm is caused by solar flares(太阳耀斑): large explosions(爆炸)near the sun that can give off lots of energy. The strong energy can stop the satellite systems(卫星系统)that control our computers, telecom networks and so on. These storms can even cause the power to go out for weeks or months.
In the past few months, scientists have recorded some of the strongest sun flares in years. The most recent one happened around Valentine’s Day, 2011. It caused radio and satellite signals to go down in some northern cities in China.
“Solar flare activity is going to be much worse than what we’ve seen in the past. We’re not talking about a few cities losing power, it could be half of the country, maybe more.” SolarStormWarning.com, a US website about space weather, warned.
Scientists say that little can be done to predict such a storm. Governments around the world are trying to work together before the next storm, although they are not sure when that may happen.

At one time or another we have all stopped to think about the weather. Some days the weather is good. Some days the weather is bad. Sometimes a day that seems bad turns out better than you thought it would. There are ways of understanding the weather. One way is to study the clouds. No two clouds are ever alike. We can see the different kinds of clouds and watch them for signs of changing weather. To forecast the weather, there are three things about clouds. you should look for: movement, colour, and change. As a rule, the higher the clouds, the better the weather. And the lower the clouds, the worse the weather is likely to be. Fair-weather cumulus clouds* are another sign of good weather. These are clouds we often see on warm summer days. Clouds can tell you if a storm is on the way. If the thick, fluffy cumulus clouds get bigger early in the day, then you know it will rain. If there is a sudden, cool and dark thunder* cloud appears, then a storm is about to break out. Colours in the sky tell us about the weather, too. A golden ring around the moon warns us that a storm is on the way. A watery yellow sunset is a sign that rain may be near. The rainbow* has a message, too. The colours of the rainbow come from the sun rays shining through falling rain. If you see the sun in the east and a rainbow in the west, the rain may be coming your way. If the sun is in the west and the rainbow is in the east, the rain will be moving away from you.
