Hey everyone, welcome back to Meteorology Matters.
We talk a lot about forecasting
and understanding typical weather patterns,
but what about those events
that just seem to defy explanation?
You know those moments when you look up at the sky
and think what in the world is going on?
Well today we're gonna explore
some of those unusual weather events
and we've got a fascinating discussion lined up.
And before we dive in, a quick reminder
to follow meteorologist Rob Jones on Instagram.

Okay, so let's start by taking a trip back in time
to 1950s San Francisco.
I mean, imagine this bustling city, right?
But instead of the usual hustle and bustle,
there's this unsettling red tinge to the fog.
It's like something out of a movie, right?
It's true, it wasn't a scene from a Hitchcock film
though it was a real event,
a top secret military experiment called Operation Seaspray.
Operation Seaspray, that sounds ominous.
What exactly happened?
Well, what's so captivating about Operation Seaspray
is that it involved the deliberate release of a bacteria
called serratium recessins into the air over San Francisco.
Wait, they released bacteria over the city on purpose?
Yeah, the idea was to study how a potential bio weapon
might spread through a densely populated area.
So they basically turned the city
into a giant open air laboratory?
Yes, and they use serratium recessins specifically
because it produces this bright red pigment,
made it easy to track its dispersal.
Okay, so they could see where it went,
but what did they find?
Well, what they found was that the bacteria spread
much farther and wider than they anticipated.
It even reached suburbs miles away from where it was released.
Wow, so it really got around, huh?
I mean, it's a little unnerving to think about,
but was this bacteria actually harmful?
Well, that's where things get a little complicated.
See, at the time, serratium recessins
was thought to be mostly harmless.
It was really only known for like,
causing discoloration in food.
But shortly after the experiment,
there was this unusual spike in cases of things
like urinary tract infections and pneumonia in San Francisco,
and guess what?
They identified serratium recessins as the culprit.
Oh no.
So an experiment that was intended
to understand the risks of a bio weapon
ended up causing real harm to the city's population.
Yeah, it's a tragic situation.
One patient who was already recovering
from surgery actually passed away.
That's awful.
It really makes you question the ethics
and oversight of an operation like that.
It absolutely does, and it serves as a stark reminder
of the potential for these unforeseen consequences,
especially when you're dealing with something as complex
and unpredictable as the environment.
Definitely, and I think this event really played
a significant role in shaping those future regulations
surrounding bio weapon research.
Didn't know it's a cautionary tale for sure.
It reminds us to think critically about impact
of human actions on the natural world.
I mean, it kind of makes you wonder, right?
Are there similar events happening today
that we might not even be aware of?
It certainly makes you think.
Okay, well, speaking of unexplained events,
let's shift gears a bit and talk about some
of this peculiar fog that's been plaguing parts of Florida.
Now, you mentioned earlier that Florida has a fog season.
Can you explain that a bit more for our listeners?
Sure, yeah, Florida typically experiences this period
of increased fog, you know, from late fall to early spring,
and it's due to a combination of factors.
You have cooling temperatures, ample moisture
from the Gulf of Mexico and, you know, calm wind conditions.
So fog itself isn't unusual in Florida,
but recently there have been reports of fog
with some pretty unusual characteristics.
What can you tell us about that?
Yeah, so there have been reports
of this unusually dense fog, almost like a thick smoke,
you know, and it's accompanied
by this strange, almost chemical odor.
A chemical odor, now that's strange.
Have there been any reports of people experiencing,
you know, health problems or anything like that?
There have been.
Some residents have reported experiencing, you know,
respiratory issues and other health concerns.
So there's definitely a lot of anxiety surrounding this fog.
I can imagine.
So what do we know about the potential causes of this?
I mean, is there anything to be concerned about?
Well, it's important to approach these reports
with, you know, a balance of concern and skepticism
while fog can trap and amplify existing odors,
making them more noticeable.
It doesn't typically have a smell of its own.
So that chemical smell, you know,
it could be originating from a nearby source
that's just being, you know, magnified by the fog.
So the fog itself might not be the culprit,
but rather just carrying an existing smell.
Exactly.
That makes sense.
But what about the reported health effects?
Could the fog itself be causing those respiratory issues?
It's possible.
While it's true that fog can worsen, you know,
respiratory problems, especially for folks
with asthma or other sensitivities,
it's important to consider other factors too.
You know, winter is a time when viruses are more prevalent
and the symptoms that are being reported
could just be related to a seasonal illness,
rather than the fog itself.
Right, so it might be a case of mistaken identity.
Exactly.
Okay, so we have this strange fog in Florida
that's causing quite a stir.
It's a good reminder that while we might understand
the basics of weather phenomena like fog,
you know, there's still many nuances and complexities
that can surprise us.
There are.
And sometimes, you know, the answer might not be
as dramatic or sinister as we initially suspect.
That's very true.
Okay, well, let's shift gears again
to a completely different weather event.
The extremely cold winter
that much of the country just experienced.
I mean, I know a lot of folks were bundled up
in their warmest layers for months on end.
Yeah, it was a long one.
This past winter saw below average temperatures
across a huge portion of the United States,
Kentucky, for instance.
They experienced some exceptionally frigid conditions.
It really felt like we were stuck
in a deep freeze for ages.
What I found particularly interesting though
was that despite this record breaking cold,
many areas actually experienced below average snowfall.
How is that possible?
That's a great observation.
And it speaks to the complexities of weather patterns, you see.
While it might seem counterintuitive,
warmer temperatures even in winter
can actually lead to less snowfall overall.
Wait, so warmer temperatures even in winter
can mean less snow.
That seems kind of backwards.
It does, but it highlights the interconnected nature
of our climate system.
You see, climate change is leading
to overall warmer temperatures,
which ironically can sometimes result in less snow
in certain regions, even though those same regions
are experiencing periods of extreme cold.
So we've got this strange mix of extreme cold
and below average snowfall.
What's the story behind that?
Is there a scientific explanation
for this unusual combination?
Well, one factor to consider is the polar vortex,
that large area of low pressure and cold air
that circulates around the Arctic.
The polar vortex.
Right, sometimes this vortex can weaken and split,
sending surges of that frigid Arctic air southward.
So the polar vortex is like this swirling mass of cold air
that occasionally dips down from the Arctic,
bringing the chill with it.
Precisely.
And this winter we saw a particularly strong
southward dip of the polar vortex,
which explains those widespread cold temperatures.
However, snowfall is influenced by a multitude of factors,
including the amount of moisture in the atmosphere
and the tracks of storm systems.
So even though the polar vortex brought the cold,
the conditions weren't necessarily right
for significant snowfall in many areas.
That's right, it's a reminder that weather
is a complex system with many interconnected parts.
Just because one element is extreme
doesn't necessarily mean others will follow suit.
It's fascinating, isn't it, these unusual weather events,
like the mysterious fog in Florida
and the record breaking cold with less snow.
It really makes you think about the intricate workings
of our planet's atmosphere.
It does.
And on that note, we'll wrap up part one
of our discussion on unusual weather events.
Stay tuned for part two, where we'll
delve deeper into the science behind these events
and explore their potential implications for the future.
It really is.
And it just shows how important it is to keep
researching and observing so we can better understand
these complex weather patterns.
Yeah, for sure.
Now let's dive back into this polar vortex for a bit.
I'm curious to understand exactly how this swirling mass
of cold air manages to plunge so far south
and what role it played in those unusual weather patterns
we've been discussing.
OK, so imagine the polar vortex like a spinning top, right?
It's typically confined to the Arctic region.
It's held in place by this band of strong winds
high up in the atmosphere called the polar jet stream.
Now when this jet stream weakens or becomes kind of wavy,
it can allow the polar vortex to, you know,
bulge or even split sending loaves of that frigid Arctic
air southward.
OK, so a wavy jet stream lets the polar vortex escape,
kind of like a crack in a dam unleashing cold air
into those lower latitudes.
That's a great analogy.
And this winter, a combination of factors, you know,
things like high pressure over the Arctic
and this unusual warming in the stratosphere,
they disrupted the jet stream allowing the polar vortex
to make that southward excursion.
So even though the polar vortex brought the cold,
the conditions weren't always right for significant snowfall
in many areas, right?
Exactly, snowfall.
You know, it isn't just about temperature.
It's also heavily influenced by the amount of moisture
in the air and the cracks of storm systems.
So in many areas that experience that extreme cold,
the air was simply too dry to produce much snowfall.
It's a good reminder that weather is rarely straightforward.
But this southward shift in the polar vortex
does make you wonder, could climate change
be playing a role in these more frequent and dramatic dips?
That's a question scientists are definitely exploring.
While polar vortex itself is a natural phenomenon,
there's growing evidence suggesting that climate change
may be influencing its behavior.
Some research indicates that warming in the Arctic,
particularly the rapid loss of sea ice,
could be altering the jet stream,
making it more prone to these wavy patterns that
allow the polar vortex to break free.
So the warming Arctic might actually
be contributing to these intense cold snaps
in other parts of the world that's
both fascinating and kind of alarming.
It is.
It highlights the complex and interconnected nature
of our global climate system.
What happens in one region can have ripple effects
across the entire planet.
And speaking of ripple effects, let's
circle back to that mysterious fog in Florida for a moment.
We talked about some possible explanations,
but is there any indication that this fog event could
be linked to something larger, perhaps even
a consequence of a changing climate?
That's a great question.
And it's important to emphasize that drawing definitive links
between individual weather events and climate change
is a complex process.
However, we can look at broader trends
as global temperatures rise.
We expect to see shifts in weather patterns,
including changes in humidity levels and air circulation.
These shifts could potentially contribute
to more frequent or intense fog events in certain regions.
So while we can't definitively say
that this particular fog event in Florida
was caused by climate change, it's
possible that we could see more events like it in the future
as our climate continues to change.
That's a reasonable conclusion.
And it really just underscores the importance
of studying these events, gathering data,
and refining our models to better understand
how a changing climate might be impacting weather patterns
around the globe.
I want to go back to Operation Sea Spray for a moment.
The fact that such an experiment was conducted
and releasing bacteria over a populated city,
it's quite shocking.
What were the long-term ramifications of that event
beyond those immediate health concerns?
Operation Sea Spray had a profound impact,
not just on the scientific community,
but also on public perception and policy.
The incident raised these serious ethical questions
about the use of biological agents,
the potential for unintended consequences,
and the need for informed consent in scientific research.
It sparked a lot of public outrage,
led to congressional hearings, and ultimately,
it pushed for stricter regulations
surrounding biological research and the development
of bio weapons.
So this one event, as unsettling as it was,
played a pivotal role in shaping how
we approach scientific research and the ethical considerations
that come with it.
Absolutely.
It serves as a stark reminder that scientific advancements
must always be weighed against their potential impact
on human health and the environment.
It's a lesson that continues to resonate today
as we grapple with these new and emerging technologies.
It makes you realize that our understanding of weather
and the atmosphere is constantly evolving.
And sometimes it's these unexpected events
like Operation Sea Spray or this unusual fog in Florida
that force us to reexamine our assumptions
and push the boundaries of our knowledge.
It's amazing how these seemingly isolated weather
events, like the fog in Florida or the record breaking cold,
can actually tell us so much about how interconnected
our planet's climate system really is.
It really is.
It's like trying to put together this giant puzzle.
Each weather event gives us a clue.
And as we study those clues, we start
to understand the bigger picture, those intricate forces
at play.
And as we've been talking about, some of these puzzle pieces
are getting weirder, raising those questions about how
climate change is shaping these extreme or unexpected events.
Exactly.
While we can't say for sure that any single weather event is
directly caused by climate change,
we can look at the long-term trends and patterns.
You know, what we're seeing is that many of the events we've
talked about, like extreme cold, unusual fog
shifts and precipitation, they all line up
with what climate models have been predicting.
So these unusual events could be like a sneak peek
into a future where extreme weather becomes more common
and more intense.
It's definitely something we need to think about.
And that's why it's so important to keep investing
in climate research, monitor these changes,
and come up with ways to reduce the risks.
Speaking of reducing risks, what can people
do on an individual level to be part of the solution?
It can feel pretty overwhelming when we're talking
about these huge global challenges.
It's true.
Climate change can feel like this giant problem.
But individual actions, when you multiply them
across communities and nations, they
can really make a difference.
Even simple things like using less energy,
choosing sustainable transportation, and supporting
policies that promote clean energy, all of that adds up.
So every little bit helps.
Absolutely.
And beyond what you do personally, staying informed
and being part of the conversation is really important.
You know, support organizations that
are working on climate change.
Talk to your elected officials about what you're worried about,
and be a voice for change in your community.
It sounds like knowledge is power in this fight.
The more we understand about climate change and what it might do,
the better we can make good decisions
and push for real solutions.
I completely agree.
We need to give people the knowledge and tools
to deal with these complicated challenges.
Well, we've covered a lot today from that secret bio-weapon
experiment in 1950 San Francisco to the polar vortex
and the strange fog in Florida.
Is there one main takeaway you'd like listeners to remember?
I think the most important thing to remember
is that the Earth's climate system is incredibly complex,
and everything is connected.
You know, what might seem like a random weather event
can often be linked to these bigger global patterns.
And as our climate keeps changing,
we can expect to see more of these unusual and extreme events.
The key is to stay informed, keep learning, and work together
to find solutions.
Well said.
It's a good reminder that we're all in this together,
not just with each other, but with this amazing planet
we call home.
And it's our job to protect it.
