Niamh (10) asks “How do scientists know what the weather is going to be like in the future?

Niamh, that is a question that I have asked several times over the last 20 years ….. and the answers have changed. I asked my team about their thoughts.

Niamh, the weather forecasts were initially based upon previously recorded weather patterns. Records of the what happen to the weather go back to the 19th century  and the weather experts of today look for patterns in past weather to predict what is going to happen in the future.

All the past patterns have now been computerised so part of the role of the forecasters is to get the computers to analyse the patterns and then make suggested predictions.

Nowadays the weather experts ( they are called meteorologists) also have satellite images  to help them predict the weather. They also use other sensors like weather balloons which record air pressure and temperature at different levels in their location.

Niamh, for the distant future it is very difficult to predict what the weather will be like. The weather is one of those magnificently independent variables that we still cannot control.
