@hasmis Which is the 'new baby storm in the Pacific'?
@MBoodenAK I put out the term 'storm factory' after astronomy's 'star factory'. The storm factory put out a perfect string of storms to hit California like hurricanes. No 'atmospheric rivers' here. The mechanism was an intense stream of very cold air. It dove into the warm air mass and carved out a storm. Within a day, the storm was huge. Now the factory is changing. There is a little 'pre-storm' or baby storm south of Japan on the wind chart, but it is spinning the wrong way. It probably won't thrive.
@hasmis Thx for the reply. Frankly I don't see the 'baby storm'. There is a high-pressure area S of Japan and a low-pressure area east of the Philippines. Both are spinning as you'd expect them to.
@MBoodenAK Ok, the first zoom-in is from yesterday. It shows the forming of storm#2, and the baby storm, clockwise. Picture 2 shows the baby storm more defined (from today). Just south of Tokyo. We don't know what will happen to the poor little thing.
@MBoodenAK You are right. A forced clockwise rotation would contain cold air (high pressure), and could not form a storm. I'm expecting this thing to blink out, and the rebound will form a new storm. However, these are all traditional definitions of the weather tribe. :)
@MBoodenAK A narrow air jet will form curls on both sides. Here, the east side spits out self-contained hurricanes to California, and the west side forms clockwise-spinning blobs of cold air that will just die.
@hasmis I think I see what you mean, however switching to MSLP shows we're dealing with a high-pressure area rotation clockwise, not low-pressure and so definitely not the inception of any storm? (image from Tue 10 Jan 2023)
