Dry And Wet Days In 2011, 2012, And 2013
Donald A. Windsor
In 2013 we had 3 wet days for every 2 dry days.
I live in the City of Norwich and define a wet day as any kind of aqueous precipitation within a 24-hour day. That is, a sunny day can still be a wet day if we had snow flakes at 2:00 in the morning.
I started recording these data back in November 2010 because it seemed as if I could never get several dry days in a row. Sure enough, we were actually getting a wet day for every dry day.
Here are my data for the past 3 years.

The data show that 2011 and 2012 had about 1 dry day for each wet day. However, 2013 was much wetter, 2 dry days for every 3 wet days. What will 2014 look like? Stay tuned.
