Description

These plots show Probability Density Functions (PDFs) of daily average atmospheric pressure at stations in the UVic School-Based Weather Station Network. The vertical red bars show a histogram of daily average pressures. The data is fitted to one of three different probability distribution functions (Maximum or Minimum Gumbel and Gaussian), shown with a blue curve. The Gumbel distributions are appropriate for fitting sets of extreme values .e.g the set of maximum pressures. We select the fit function with the least error.

The plots are shown for the entire year and for each season. The seasons are defined as follows:

  • Winter — DJF: December, January, February
  • Spring — MAM: March, April, May
  • Summer — JJA: June, July, August
  • Autumn — SON: September, October, November
