Instructions of the strip 
To use the slider, place the red arrow next to the date of the Sunday of Passover that year using the slider below. 
The right slider is used to adjust the graph in line for Lorraine. It is used to other areas further south by a downward shift. 
Then you look at the weather for your chosen date and you see the corresponding graph. 
 
The black horizontal line corresponds to the high ripple 
The arrows are the short waves. 
One of the six cases presented allows you to interpret the weather at the time of your choice. 
The dotted circles represent the movement of air masses 
Periods without rain where the lines do not intersect. In summer, it is below the blue square and in winter, above the yellow squares 
 
A cycle starts with a week of good, then alternating rain and beautiful when it rains more. After heavy rains, it's a new cycle. 
In autumn and spring periods without rain are short 
The odds ratio is 4/5 for the dry and 3/5 for the rain.
