Stockholm’s Arlanda Airport has created a “Climate Portal” to give passengers a preview of the weather at their destination – or at a destination they might want to book for a future trip.

The portal has three rooms – titled HOT, COLD and BIG – that use sound and image technology plus wind and temperature simulations to somehow transform online weather data into the physical experiences of being in various cities.

Here’s a short video the Arlanda Airport put together to explain:

Why create a weather portal at the airport when passengers are about to board planes which are already portals to new places?

It’s fun, of course, but as airport representatives point out, a weather preview is also a good reminder that you may need to do a bit of last minute shopping for sunscreen for that warm weather destination.

Look for Arlanda’s Climate Portal in Terminal 5, near Gate F26,  through August 31.
