I manipulated daily rainfall variability by changing the daily mean rain (DMR, rain volume on rainy days averaged across years for each day of the year) by ± 20%.
These lower ozone concentrations in June and July coincide with high daily rain frequency in these months [ 42].
A flattened bell-shaped seasonal function determines the daily mean rain volume (DMR), i.e., the mean rain volume for a given day of the year averaged for rainy days across years.
I simulated the change of stochastic daily rain patterns by increasing the seasonal amplitude of daily mean rain volume (DMR) matched by a decrease in the seasonal occurrence of rainy days so that the mean annual volume remained unchanged.
The change of daily rain pattern was achieved by increasing the seasonal amplitude of daily mean rain volume (DMR) by -20%, -10%, 0%, 10%, and 20% in the ReGen time series generator [ 20].
Nimbostratus clouds hang low and heavy in the sky, and mean rain is imminent.
Purple or green means rain or snow, respectively.
But we're anticipating some heavier rain in the upcoming weeks, and that means rain boots.
Mean annual frequency of collapse.
