Average rainfall for each day of the week is shown for rain falling between noon and midnight (“Afternoon”) and between midnight and noon (“Morning”).  Storms tend to grow most vigorously during the afternoon hours, and the authors suggest that pollution causes these storms to grow even more vigorously than they would in “clean” air.  It is possible that these extra-strong afternoon storms during the middle of the week deplete the energy for storm formation so that less is left for storms that might form the next morning, and that this is why the morning storms tend to be weaker during the middle of the week.
