In our great debate regarding our local climate admist our great drought lots of banter was exchanged regarding changes in our local rainfall. Some thought this drought was the new normal, others that our rainfall was feast or famine, along with various other theories. So I decided, on my day off today, to try to start answering that question. The weather station at kmdt has been in same place since 10/1/1991. So using NOAA climate viewer website I downloaded daily summaries specificaly regarding precipitation from 1/1/1992 through 12/31/2022, a good 31 years. I filtered out all dates below 0.01" qpf, then through a formula assigned each event a bin number, starting with 1 going through 21, associated with 0.25" stepwise increase up to 5", with last bin any events that produced 5"+ a year. Thus I know a table showing how many of each rainfall bin occurred in each year, qpf sum for each bin/each year along with average amounts. I will post tables tomorrow but in summary: - Rainfall events - the ratio of sum of all - we underestimate just how dry 1992-2001 was and just how wet 2002-2022 were. Comparing those time periods we on average have seen 12 more events per year since 2002 then we saw from 1992-2001 - more events leads to more chance for big events. For events >1.00" the average yearly count from 1/1/92 through 12/31/2001 was 8.8. 1/1/02 through 12/31/2011 was 12. 1/1/2012 through 12/31/2022 was 10.7. I need to still look more in depth regarding distributions of the events greater than 1", but due to small numbers I might have to expand data set, but that involves ingesting numbers from previous official locations, like capital city. I also want to look more into month specific breakdowns. My best guess is that the only proven trend regarding precipitation I've seen is it has been raining more days and also more yearly. Probably not as extreme as it seems compared records from the whole official records going back to 1889 due to location changes and equipment sensitivity but still substantial. The raise in average low temperatures provide further proof of the increased moisture. Regardless of how many days it rains, the distribution is remarkably stable regarding what percentage of those events are above or below 1". A combination of increased moisture in atmosphere and rainy period has lead to those greater than 1" days producing more rain, maybe psychologically even more than substantially. This year has been a throwback to the 2001 and prior eras and the difference between this year, last year somewhat vs last 20 year and recentcy bias make a bad combination.
