All About The Weather
We love the weather in the UK. In fact, it's one of the Sunny D team's favourite subjects. So we've rounded up some weather facts for our Sunny D followers:
People love talking about the weather. Long before forecasts appeared on the television, online or in newspapers people looked for signs of changes in the weather in the way that animals or plants behaved. When the pressure drops a sign of bad weather about to strike can be ants moving to higher ground, pine cones opening and sheep's wool uncurling. Scientists have also noticed that sharks swim to deeper water when a storm is approaching.
About 70% of the Earth is covered with water
Most of this lies in the oceans. Much of the rest of the water is in the ice sheets, glaciers and underground.
No new water is ever made
The rain we see has fallen millions of times before. This is called the water cycle.
The tallest cloud...
...is the giant cumulonimbus which can reach a height of 11 miles and can hold an amazing half a million tonnes of water.
These occur when the air becomes warm and humid. Huge clouds form in the sky and winds begin to blow.
There are about 16 million thunderstorms a year throughout the world.
Thunder and lightning happen at precisely the same time but we see lightning first because light travels faster than sound. The next time you see a flash of lightning start counting. If you get to five seconds before you heart the clap of thunder, then the storm is about 1.2 miles away from you.
In the northern hemisphere winds flow from west to east
This means that an aeroplane flying from America to England could arrive half an hour early because it has the wind behind it. But it could take half an hour longer to fly back when it is flying into the wind.
The windiest place in the world?
This is the George V Coast in Antarctica – where speedy winds of 200 mph have been recorded.
Hurricanes can do incredible damage
They were first given names in the 19th century by an Australian weather man called Clement Wragge. He used the names of people he had argued with for very violent storms. Today, we use an alphabetical list of pre-approved names to use for the coming year's hurricanes. These lists have been generated by the National Hurricane Centre since 1953. At first, the lists consisted of only female names but since 1979, the lists alternate between male and female. The two 2015 hurricane names are Ana and Bill.
