We are Blessed indeed, as we receive another glorius week of Indian Summer on the coast! 🌅

This gives me a tingle in the tummy!

Inspiring me once again! I will watch Haskell on you tube and will check out this book. Thanks, Kate, for reminding us of these good things.

Was an absolutely gorgeous Thanksgiving long weekend!

That is a pretty nicely graded road!

Hi Kate,
Thought this post by CHeden (cottonwood) from the comment section on Weather West is worthy for folks to read. He is around 70 years old with wisdom and perspective and very knowledgeable about climate patterns. I think his hypothesis and description of why our weather and jetstream is behaving different could be very correct.
“It’s not just here. The pattern/climate change(s) is global, most noticeable in the NH….though the southern hemisphere is also going through their woes as well.
That takes any “local” conditions pretty much out of the discussion.
The only thing that can affect planetary climate like this is rooted in the troposphere and stratosphere.
What we’re seeing is the increase in GHG/water vapor is sequestering heat near the surface (lower-mid troposphere).
As a result, the upper troposphere and stratosphere are cooling.
Given that cool air wants to sink, the atmosphere is becoming stratified, which inhibits deep-layered storms from developing; as well as increasing the overall size/strength/subsidence of high pressure cells.
However, air flows from high’s into low’s. That means that higher pressure cells are capable of providing more inflow/energy into a developing cyclone.
IMHO, that’s why once a “rare” storm gets going, the lows deepen even more than usual since it’s feeding off of higher heat and moisture content from the surrounding H.P.
So, overall there are less storms, but those that do develop can be more powerful and impactful.
Lastly, another result of increasing subsidence aloft is that our wind flows are becoming more “horizontal”…meaning less lift/ascent is present. I think this is why our inversions are more pronounced, with the air above the surface boundary not mixing downward. Hence, we get AR’s which are really just juicy air flowing horizontally around the periphery of H.P. and L.P. cells. Perhaps this is the reason why we haven’t seen a lot of surface wind with most of our rain events?
This is not to ignore Hadley flow which also produces mid-latitude H.P./subsidence, nor a general weakening of the mid-latitude jet streams…but I do think that the main culprit is GH gasses mucking up vertical energy transfer (Kinematic Heat Flux) that’s impacting the development of the low’s and high’s that drives our weather/climate.”

Thanks so much Paul, for sharing this informative writing. It is helpful to understand more thoroughly, the reasoning behind the climate shifts.

Oh heavens! This week seems to be slipping by in warp speed! I ordered the book you suggested (the same one you quoted here) from our library. It’s there waiting for me. 😉 Thanks for the serene shot of Big Sur’s beauty.
Beautiful.
