Weather observation during summer

Weather observations during summer time - The test of the Seven Sleepers’ rule

You should have had a look at worksheet one, in which you can interactively predict your summer.
Then you should have your weather sheet ready. (download worksheet)

Select a city in Central Europe and fill the table.

 Also, did you know that there is a European Weather chain, also for schools?

Example:

We have selected a school in Austria (Hauptschule II in Gmuend, Niederoesterreich, at the frontier to the Czech Republic))

Here are the weather facts of the summer of 2001.

1. June 2001, in red: max temp, in black: day average, in blue: min temp

2. July 2001, in red: max temp., in black: day average, in blue: min temp.

3. August 2001, in red: max temp., in black: day average, in blue: min temp.

But we can also add another definition considering the rainfall.

The minimum definition of a “good summer” day could be the absence of rain.

4. Rainfall in  June 2001

6. Rainfall in  August 2001

Now a combination of the definitions:

A good summer has daily maximum temperatures over 20 C and little rain (below 10 mm).
This includes small thunderstorms which are also typical when high temperatures occur.

Another year was 2003 when the Rule was perfectly right.

And how did it affect you in your home region in 2001 and 2003?
What is your opinion on the Seven Sleepers’ Rule now?

And you certainly know why we assume only a 75% probability for the Rule and not 77% or even 89% as in our case.

Further discussion

1. We have chosen the daily maximum temperature to define “summer”. What else could you select?

 2. What other weather rules do you know?

3. Why is a hot summer rather fun for the city dwellers and not for the farmers?

4. Modern weather predictions are so different. Use the LINKS and find out how.
