Worksheet: Farmer's predictions

Sheet 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 therefor 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.

Watch the three simulations carefully and answer these questions:

1) Simulation 1 shows the following situation:

a) normal summer in Central Europe
b) wet summer in Central Europe
c) hot summer in Central Europe
d) rainy summer in Central Europe.

2) Fig. 3 shows the following situation:

a) normal summer in Central Europe
b) wet summer in Central Europe
c) rainy summer in Central Europe
d) hot summer in Central Europe

3) Fig.4 shows the following situation:

a) normal summer in Central Europe
b) wet summer in Central Europe
c) hot summer in Central Europe
d) mediterranean summer in Central Europe

4) In Fig. 3 the Azores High pressure area ...

a) pushes up to the North East and brings sunny weather with it.
b) pushes up to the North and brings sunny weather with it.
c) pushes up to the East and brings wet weather with it.
d) pushes up to the West and brings wet weather with it.

5) In Fig. 3 the Azores High pressure area ...

a) does not reach far enough beyond the Alps and cannot bring cold weather to Central Europe.
b) reaches beyond the Alps and brings warm weather to Central Europe.
c) does not reach far enough beyond the Alps and cannot bring warm weather to Central Europe.
d) reaches far enough beyond the Alps and brings cold weather to Central Europe.
