Forecast Discussion

That’s probably it, a few inches of wet snow for A-Basin.  The southern hemisphere is ramping up for winter.  I may occasionally post about.  I am studying the southern hemispheres pattern and how it relates to the northern hemisphere.  

I will keep an eye out for snow chances and will post when something comes up.  Thanks for reading and all of your questions.  Much more to come over the summer about this historical winter and what’s to come this fall and winter.  Season in pictures is up next.  


Video of the LRC Cycle Comparison 22-23


This took a little more work than usual, because I couldn’t find a good format to compare the three cycles.  I finally settled on trimming each cycles width so that they could all fit on the screen.  

The video moves at a slow pace, but even with the slow pace, it is hard to see everything on the screen, so use the slider to move at your own pace. 

I am really proud of this video because first, it shows the fluctuation of the amplified pattern in each of the 3 cycles.  Second, the storms are closely synchronized.  With each frame advance, it is a quarter day.  You can see how the storms in each cycle closely follow the same track with slightly different timing.  Lastly, with the amplification, you can see how much the size and scope of the storms change.  Especially the California storms.  The amplification drops the storms to a more linear flow into the Sierra.
