Fair weather often seems to play hard-to-get on warm season weekends. During the work week, we toil under buzzing fluorescent tubes, teased by the orgy of photons just beyond the windows. But when the weekend arrives, too often it seems to bring gray, drizzly skies with it, ruining countless outdoor plans.
Well, this phenomenon is not merely the product of pessimistic imaginations, it seems. A study conducted at by Arizona State University researchers found that it is 22% more likely to rain on a weekend than a weekday, based on over 50 years of weather data from the Eastern Seaboard. To make matters worse, the researchers hypothesize that this rain is OUR fault, because it is likely due to the emissions from our internal-combustion vehicles. Automotive pollution from millions of commuters generates tons of tiny airborne particles called aerosols, and these gather in the sky to become nucleation sites, where water vapor condenses into raindrops. Stupid climate karma.
Owing to a similar mechanism, a study in 2017 showed that lightning strikes are approximately twice as common over oceangoing shipping routes compared to the general atmosphere. This is owing to the aerosols emitted by container ships, which can freeze high in the atmosphere and jostle against one another to build up electric charge. This effect is known as “aerosol convective invigoration.”

Surely if that logic holds true, there should be less rain on the weekend as there are fewer airborne particulates to seed rain.
How about this logic: in any randomly occurring event, there will always seem to be a pattern. This it simply a fluke of randomness.
Ha, I work shift work, days and nights, and it still allways seems to rain on my days off!!!

That would be true, except for that the particulates acumulate in the air until they get used, and it takes some time for enough to acumulate to form rain. My guess is that as soon as particulates are stopped from being added to the atmosphere, they slow down enough to allow water to condensate on them. So… Rain on the weekends.

I’d think it was more a question of characteristic time of water accumulation on the particulates, i.e. it takes about 5 days for particulates to condense enough moisture for it to rain, and then that rain takes any remaining particulates with it.
jchristman: The phenomena involved are related to cloud seeding, a proven technique for influencing precipitation. I would assume the study used a large enough sample size that a 22% deviation is statistically important. On the other hand, I always assumed it was observational bias – I only notice if it is raining when I want to go outside.
well theres only one way to fix that: four day weekends, or maybe two days on one day off and then three days on one day off or maybe we could figure out a six day week the possibilities are endless but one things for sure, something must be done.
Research may have shown that it rains more on weekends but their hypothesis as to the cause of that rain is untested. It’s little more than a guess.
I suck.

The problem with Enginerers is that they are so caught up in their diploma degrees that they forget grade school commen sense.

I loved these informations from this damn interesting. These informations are really interesting and funny. Hope Damn Interesting will always upgrade itself.
It rains on the weekends due to weather modification and the war By the elites to psychologically keep us peasants down and stressed out. Wake up people it’s hidden in plain view.
can someone please give the name of the reseaarch in 19998 ?
I need it immediately for a research
I was sure that rain fell more frequently on the weekend! Thanks for the proof.
