Tropical Drama 96L Battles SAL. A Lesson In Hurricane History and Hurricanes That Are HOME GROWN Like Katrina, 1935 Labor Day Storm
So much to say but not sure where to begin. Let's begin at the beginning as some Sister dancing on a mountain top in the Alps taught me that when I was a little girl. Let's start with our star of the hour Invest 96L. The above visible satellite image is from NRL and shows a neat, tightly wound tropical wave off the coast of Africa. A little low but staying low to avoid the Saharan Dust to it's North. Understand the Saharan Dust Layer AKA SAL moves in real time. In fact SAL has more moves than you can imagine. It grooves, dips like it's doing the tango then shoots off towards South Florida or even makes it as far away as Texas. Spoiler Alert... Late August and September hurricanes often later follow the track laid down by SAL earlier in the season. It's not rocket science it's merely the every flowing river known as the atmosphere and the atmosphere from year to year has patterns. A strong High gets the SAL far to the West allowing for more colorful sunsets in Key West. Also a health problem for many people with breathing problems so keep that in mind.
That's not a lava lamp.
That's SAL swirling West.
Again SAL flows with the river of the atmosphere...
Again unless a hurricane is a strong Category 3 and it can make it's own steering currents to some degree due to the huge High aloft that allows the outflow to intensify into a monster.. most hurricanes follow the same steering currents that SAL and weak waves follow.
The atmosphere has many layers. Upper Level Winds vs Lower Level Winds and there's a mid layer in between where waves sometimes get lost trying to develop into hurricanes. Also Upper Level Lows sometimes work their way down to the lower level... though that's not something that happens often. Over achievers have done that in the past as well as merging with a westbound tropical wave but those are rare flowers... like that corpse flower that blooms but rarely.
That's for Jim Cantore if he's watching..
Now a let's look at a loop I love..
One reason many love the loop above is it shows us...
...the river of the atmosphere or rather...
...where the moisture goes caught in the flow.
Yes it also shows rolls forming in waves.
But it shows the flow...
Also shows available energy if a wave gets its roll on..
Water Vapor Loops shows the flow as well.
It often tells the future better than crystals ;)
Why with all the new fancy water vapor loops do I use this one?
I love this loop as it shows the whole picture.
If you use this link it allows you to see past and present better.
