Worksheet 1: Predict your summer

You remember the Seven Sleepers’ prediction on June 27th:

If it rains at Seven Sleepers’ Day, the rain will stay seven weeks more.

In this simulation you can test the prediction and its effects.

Let’s suppose that the exact date is not so essential but the days in late June.
Day 1 could therefore be June 26th,
then day 2 is June 27th,
and day 3 is June 28th.

Observe the weather (in a city in Central Europe, in your home town) during these 3 days and then move the slides according to the observed weather from sunny to rainy. And you will see what kind of summer will be this year.

Discuss with a friend:

- Why is the maximum probability you can have for a sunny summer limited?
- Why is the minimum probability also limited?

And what is the reason for a sunny summer?

Here you have 3 simulations which you should try out.

Blue indicates Low Pressure, red indicates High Pressure.
