what's up sunshine Welcome to beautiful
San Antonio Texas We are on the
beautiful Riverwalk cruising along with
our friends at Go Rio Cruises and my
captain this is Captain Joelle He's been
doing this 33 years now That is awesome
Welcome to CNN 10 I'm Koi Wire We want
to give a big congrats to the University
of Connecticut the Huskies locking up
their 12th NCAA women's basketball
championship in an impressive win over
South Carolina And on the men's side
last night right here in San Antonio it
was the Florida Gator coming out on top
with their big win over Houston So
congrats to them as well All right let's
get you your news We start today with
some of the dangerous spring weather
that we're seeing across the southern US
and Midwest Destructive storms unleashed
relentless rain and produced tornadoes
over the weekend and they've only begun
to subside at the beginning of the week
Across the central US the National
Weather Service logged at least 58
tornadoes since the storms began Those
storms dumped over a foot of rain across
the Midsouth since last week Over the
weekend more than a dozen daily rainfall
records were set in Arkansas and
Tennessee Memphis saw its wetest day
ever in April with more than 5 ines of
rain Although the rain has stopped
communities are not out of danger as
rivers continue to rise Widespread
flooding has triggered evacuations water
rescues and warnings to move to a higher
ground across Kentucky The Kentucky
River is predicted to crest at a new
record of 49 1/2 ft the highest level
it's reached since flooding in 1978
Kucky's governor declared a state of
emergency last week and urged residents
statewide to take the flood threat
seriously
Pop quiz hot shot Weather balloons carry
what instrument used to measure the
atmosphere Barometer radio son
thermostat or
animometer If you said radio son rise up
It's a small battery powered instrument
suspended below a weather balloon
gathering atmospheric data like
temperature pressure and humidity then
transmitting that info to a ground
receiver via radio The National Weather
Service has been launching weather
balloons and their attached radio signs
to make upper atmosphere observations
since the 1930s And while other methods
like Doppler radar satellites and
aircraft observations help in this
effort the National Weather Service
considers weather balloons the best
method for measuring weather factors
like humidity wind and pressure for
building accurate weather forecasts So
what happens if some of these balloons
launched twice a day from more than a
100 sites across the US no longer take
flight Our meteorologist Alli Chinchar
has more
[Music]
We are at the National Weather Service
office We're going to be running through
a weather balloon launch today There are
roughly 100 National Weather Service
offices scattered across North America
and the Pacific Islands And they're all
roughly evenly spread out so that you
get good coverage when you're trying to
give forecasts for a specific area All
of these dots here represent a site that
offers weather balloon launches twice a
day every single day The yellow dots
indicate a location that's gone down to
just one launch per day instead of the
usual two The red dots indicate where
they have gotten rid of the launches
entirely Our particular weather balloon
here is filled with hydrogen which is
then attached to an instrument called a
radio sand that measures temperature
humidity pressure as well as wind speed
as it moves up in the atmosphere Uh one
of their core functions is that the data
that we take from them twice a day is
used and ingested into weather models
that produce the forecast that you say
get on your phone or are utilized by
your local or national TV
meteorologist They can also be used in
the event of severe weather Sometimes on
extremely windy or stormy days it
actually can take two or even three
National Weather Service employees to
launch the balloons Oftent times when
you have a tropical system that is
nearing landfall or a severe outbreak
that is expected many of these offices
will actually issue extra balloon
launches perhaps one or even two more
per day Now we're actually cutting back
on the weather balloon launches rather
than adding more in times that we really
need to have the
extras All right so far in today's
episode we have talked about storms and
the best ways to predict them What about
some of the beauty that comes after the
storm Sometimes we see those rainbows
right And it turns out this everyday
marvel is more complex than you think We
all know that no two people are exactly
the same And it turns out no two people
will ever see the same exact rainbow in
the same way Why We humans each see our
own unique set of reflected light from
different raindrops from our own very
different perspectives Our me Terrell
talks to a professor of atmospheric
sciences to help explain this
fascinating phenomenon
Did you know that no two people see the
exact same rainbow Each person sees
their own rainbow These amazing displays
of nature are different for everybody
because they're created by sunlight
refracting through raindrops and then
reflecting back out And we all see
reflections from different drops
According to atmospheric scientist Dr
Steven Boozinger It seems like you're
seeing the same rainbow but in in as a
matter of physics you're actually seeing
different rainbows because you have a
different perspective slightly different
perspective So the rainbow's being made
up of different raindrops
We all know what it takes to make a
rainbow sunshine and rain at the same
time But what's actually happening
Booinger says is that as sunlight hits
the droplets it bends or refracts And
because colors travel at different
wavelengths the bending reveals them to
the human eye The wavelength of blue
light is shorter than the wavelength of
red light And the energy associated with
the blue light is higher than the energy
associated with the red light And so the
blue light tends to be bent more than
the red light And each raindrop is
actually reflecting only one color back
to us We see red on top of a rainbow and
blue on the bottom Because their
different wavelengths mean they exit the
raindrops at different angles Each
raindrop in the shower is producing one
color for your eye and then you go to
the next raindrop and it produces
another color And in some that gives you
the whole rainbow If you're very lucky
you might see a double rainbow It's a
second reflection at the back of the
drop so that the light comes out at a at
a higher angle or on a bright moonlight
night If you go out at night and there's
a full moon and you look away from the
moon there are times where you can see a
rainbow or a moon bow I guess it's
called at that point But Booinger's
favorite rainbow fact is that you'll
never find the end of a rainbow You're
on a in a helicopter or a small plane
you can see a a full circle rainbow
because the rain doesn't hit the ground
and it creates a a full circle So no pot
of gold but now you know some physics
and that's everyday science

Today's story getting a 10 out of 10 An
offline club ditching screen time for
IRL time The offline club started in
Amsterdam in the Netherlands offering a
space for folks to take a break from
their screens and all the distractions
that keep us plugged in scrolling and
those sorts of things and missing more
in-person connections with the people
around us Now there are offline club
chapters in cities around the world from
London to Lisbon to Dubai where people
of all ages are coming together for a
screenfree fun Take a look My name's Ben
Hansel and I'm city leader for the
offline club London We're pioneering a
movement to help people swap screen time
for real
time It was founded by three Dutch guys
in Amsterdam in February 2024 is just a
group of friends trying to get away from
their phones And since then it's really
grown into a global
movement So it's just a phone free event
You turn up you hand your phone in at
the start and for the next 2 hours
you're offline We'll have live music
live piano and then people will pick up
those forgotten hobbies reading
journaling writing It's really
mindful I'm not anti-tech myself I think
it's just very beneficial to get away
from tech for a few hours So I'm 23
years old In my previous startup I was
spending hours upon hours a day
optimizing video for Tik Tok making sure
it was as addictive as possible Ironic
right I think for us as humans it's
about discovering what parts of these
phones do that we want to use for good
and what parts aren't benefiting us
Our core audience is actually 90% female
ages 25 to 50 So it's not actually
really Gen Z and Gen Alpha that are
coming to these events I think they're
just the most addicted to their phones
We got weaker real world connections
It's really declining our mental health
My pep talk would just be to come to an
offline event Come and chat to me there
in person and I reckon I could convince
them to go offline for a bit All right I
want to give one more thanks to my
captain Joel Appreciate you sir And
we're going to make this a two shout out
Tuesday This one goes to the Cougars at
Hatam Killingworth Middle School in
Killingworth Connecticut Thank you for
subscribing and making us part of your
day And this one goes to John J High
School and all our Mustangs right here
in San Antonio We see you Coach A
Remember tomorrow's #youword Wednesday
You know the drill Submit your unique
vocabulary word and definition along
with your school's name and we'll choose
one fun winner to work in tomorrow's
show Let's go And yehaw y'all Hope you
float on through this day real nice Like
I'm Ky Wire and we are CNN 10
