Let’s talk about May

Now in a really good web site about weather, clouds and climate, we would have talked about May around the first of May.  But let’s face it, this site really isn’t that great.  So now we’ll talk about the climate of May on May 11th.

Below is the rain frequency climate, such as it is, for May here in Catalina.   Surprisingly, to Mr. Cloud-maven person, there is no downward trend in the chances of measurable rain from the very first days of May until the end as was expected.  Instead, each day of the whole month has about the same small chance of rain from the 35 year record mostly made by the folks (Wayne and Jenny) at Our Garden here in Catalina.

Where the rising temperature graph for May, you ask? Well, I don’t do temperature. I am cloud and rain person. A nice graph of the temperature trend for May, which we know is upward on average for the whole month, can be found here at the Western Regional Climate Center, housed at the cloud seeding-inclined Desert Research Institute of the University of Nevada which issues misleading PR pieces on cloud seeding which they conduct for the State of Nevada (no, you won’t find them, in spite of being an academic institution, doing proper randomized cloud seeding experiments, but rather bogus-style “operational” seeding.  They’d be AFRAID of doing a proper long-term, double blind randomized experiment using independent evaluators!  If I was them, I would be afraid, too, about what such an experiment might tell their long term funders!  Don’t get me started on cloud seeding discussions!

Now, where was I?

Oh, yeah, climate.  Don’t get me started about the parallels between some aspects of the purveyors of global warming info (I’m talking exaggerations, not the prospect of it which I have to grudgingly go along with, “grudgingly” because I really hope there’ll be an ice age tomorrow when I read some of the exaggerations that come out for the purpose of scaring people,  like this or that storm or tornado was due to global warming.

Yes, there are parallels between cloud seeding claims and some of the GW ones, mostly, in this writer’s opinion, driven by the need for funding.

Now, an hour later,  back to that graph at DRI….  You can see that the temperature at the U of A rises steadily throughout May on average.   We knew that already, so there really wasn’t much point in showing it, but I feel a lot better now having exhausted some hot air myself.

 

The End.
