The weather is not an easy thing to forecast.
All day and night, weathermen are collecting information from ships, planes, weather stations, and space stations.
With the help of this information, they can understand what the weather will be like during the next few days.
Although no two days will have exactly the same weather, some types of weather people can forecast.
When a barometer shows high pressure, the weather will be calm.
In winter it will be cold and frosty.
In summer it usually means misty mornings and hot sunny days.
When the barometer shows low pressure, look out for rain and strong winds.
As a result of the weathermen’s work we learn about the weather.
