The given chart illustrates the deepness of snow in a particular skiing area located in Canada over the course of 3 years.
For the first quarter of November, December and January, the amount of snow was fairly low and only stayed under the 200cm limit. The second year always had the smallest depth of snow during the time period starting from just under 100cm in November then dropping down to the lowest point of around 75cm in December and coming back up to a little bit over 100cm in January. In contrast, the snow depth of the third year always had the most snow depth over the time course, starting at over 100cm of snow in November and steadily increasing to over 170cm in January. Year one was in the middle of having the least and most snow depth during this time, going from 100cm in November and increasing to 150cm in January.
The second quarter, consisting of February, March and April had significantly higher amounts of snow, almost twice the amount that was measured in the first quarter. The snow depth of year three was always measured to be the least in this time quarter, where it stayed around the level of 350cm for the first 2 months of the quarter and dropping down 50cm in April. The snow depths in year one compared to year two were higher in February and March, starting at around 430cm and increasing to 450cm, while the second year stayed at 400cm of snow depth. But in April the snow depths of year two was measured to be the highest at over 450cm while the snow in year one dropped to around 420cm.
Overall, there was a consistent pattern of which years had the most and least snow for both time quarters except for in April where year two had the highest peak in the entire chart.
