ELI5: Explain Like I'm 5

THORPEX Interactive Grand Global Ensemble

Have you ever played a game with your friends where you all have to guess what's going to happen next? Maybe you try guessing if it's going to be sunny or rainy outside, or if your favorite team will win the game. Well, scientists who study weather use a similar game to predict what the weather will be like across the whole world.

This game is called THORPEX Interactive Grand Global Ensemble, or TIGGE for short. Scientists around the world work together to play this game, and they use lots of big computers to help them make their predictions. They look at things like temperature, pressure, and wind speed in the atmosphere to try to guess what will happen in the future.

But like any guessing game, sometimes they get it right and sometimes they don't. That's why they work together in a big group - they all make their predictions and combine them together to get a better idea of what's going to happen.

So why is it so important that scientists predict the weather? Well, knowing what the weather will be like in the future can help us prepare for things like rain, snow, or storms. We can make sure we have the right clothes to wear or that we're ready to stay safe if a big storm is coming. And sometimes, predicting the weather can even help us plan for things like growing crops or fishing, so that we can have enough food for everyone.

In short, TIGGE is a game that helps scientists predict the weather across the whole world by guessing what will happen in the atmosphere, using big computers and working together in a group. This helps us plan for different weather conditions and make sure we're ready for whatever Mother Nature has in store for us.
