“Plan B” when monsoons fail

Florida doesn’t have monsoons,

although the summer showers are often mistaken as such.


What makes them different?

Florida’s summer convective showers are fed by “low atmosphere” lows (caused by daytime heating), stoked by upper atmosphere instability and super charged by colliding landward-flowing peninsular sea breezes.

The key here is that the winds – like clockwork – “reverse directions”.

Come wee nighttime hours – while the fine citizenry of the state slumbers – the winds grow aimless and U-Turn there way back out to sea.

That’s in contrast to India:

Its sea breeze blows nonstop – 24 hours around the clock – funneling maritime air into a giant “upper atmosphere” low that perches itself over the peninsula all summer long.


My point?

Florida doesn’t have monsoons, but it does gets monsoonal-worthy rain totals,

And in some cases even makes monsoons look minuscule!

Summer rains are also “officially” described as monsoonal in the American Southwest, despite being a small fraction of Florida’s summer wet-season drenching.


Turns out those miniscule monsoons were complete “no show” in the Sonoran this summer.

That has its perennial-flowing San Pedro River – a thread-like riparian ribbon of florescent green in an otherwise cactus strewn basin – running at a historic low.

The word is it may very well run dry.

The hope on the horizon is the El Nino.

It’s late fall surge has meteorologists now classifying it as a moderate to strong event.

That could make it a wet spring in the Sonoran Desert.

That’s what I call a good Plan B!

(Not that Plan A was much anyhow … at least compared to Florida’s “non-monsoonal” wet season.)
