The diagram illustrates information about how deep is the snow in a specific ski area in three different years.
Overall, over six months period from November to April, the average depth of snow showed an upward trend across all three years. The lowest depth was recorded at approximately 60 cm, while the greatest depth reached around 470 cm.
In year one, the thickness of the snow layer gradually increased from 100 cm to 150 cm during the first three months. Then the snow depth experienced a steep rise, peaking at 450 cm on March. In the last three months, the level of snow stabilized at around 400 to 500 centimeters.
In the second recorded year, the trend is generally similar to that of the first; however, the figures in the first year are typically greater with the only exception being the final month. The snow level fluctuated at around 100 centimeters in November, December, and January. Then a sharp increase occurred in February. The main difference is that the snow depth continued to rise steadily, reaching its peak of 470 centimeters in April.
In the final recorded period, the figures rise slowly, from 110 cm to 160 cm in the span of first three months, higher than those from the first two year. After that, the data experienced a dramatic surge, reaching its highest depth at 350 centimeters in February. Unlike the other two years, the depth of the snow slowly declined to 300 centimeters in April.
