Hi, I'm Martin, with your Newsround

udpate, and we're talking

about the freeezing temperatures

that have hit the UK.

But it looks like those

of you in Scotland will be

seeing the worst of it.

A red weather warning

has been issued.

Here's more.

At the moment, most

of the UK looks like this.

It's cold, it's windy and it's

covered in the white stuff.

Lots of you guys have been

enjoying the snow...

THEY SCREAM

And in some places, there's

going to be a whole lot more of it.

A red warning has been issued

in Scotland by The Met Office,

who monitor the weather.

That's very rare.

It's the first time in five years

that one's been issued for snow.

It's this area called

the central belt -

from Edinburgh to Glasgow -

that's been affected by the warning.

It means that problems

like power cuts are expected.

Weather experts want people to take

care to stay safe in the snow.

At least 400 schools were shut

in Scotland this morning and,

with more snow to come,

there'll be plenty of time to make

snow angels tomorrow.

My hat came off!

It wasn't just Scotland that saw

schools close today.

Kids around the country had a bonus

day off because of the bad weather.

Here's what some of

you have getting up to.

Hi, we're Isla, Jess

and Campbell, and we're from...

The Isle of Scotland!

And we're off school

today, and we're going...

Sledging!

THEY SCREAM.

Hi, my name is Harriet,

and I live in Bolton.

It's freezing cold.

There's only been a little bit

of snow, but I'm lucky

because my school's been open.

It's minus five degrees.

Today, school is closed,

so I'm going to do snow angels.

And snowballs.

And snowmen.

We're not at school.

We're from Edinburgh.

It's snowing today.

We went sledging today.

Hi, my name is Abby,

and I'm six years old.

I'm from Glasgow.

My school was closed,

so I get to play in the...

snow!

I'm going to make a snow angel.

Well, that lot were

wrapped up to stay warm.

But it's not just the snow

that makes you feel cold

on days lilke today -

there's also something called

the wind chill factor.

Sounds interesting.

So what is it?

It is absolutely freezing

at the moment, but did you know

that the temperature we feel

is different to the actual

temperature of the air around us?

Now, outside the studios

here at Newsround, it says it's

around minus one degrees,

but it also says it

feels like minus seven.

Now, that's because of something

called the wind-chill factor.

Weather experts often call

wind-chill the 'feels

like' temperature.

It's worked out using the air

temperature, humidity -

that's how much water vapour

is in the air - and wind speeds.

All this information is combined

with the science of how heat is lost

from the human body.

So, on a cold, windy day like today,

why does it feel even

colder than it really is?!

On a calm day, our

bodies insulate us.

We give off heat, so we warm

the air around us.

It's a bit like having a warm

force field, or blanket.

But when it's cold and windy,

the breeze hits the face and cools

the skin to almost the same

temperature as the air.

It essentially blows the blanket

away, so we feel much colder.

So, there you have it, wind-chill!

Pretty cool, eh?

Woo!

It is so windy! Help!

This pair is having a great time

exploring his snowy enclosure at

Chester Zoo. Animals like this tiger

braved the weather to get fresh air

and some decided to see what it

tasted like. Why not?

Remember, there's loads more

from Newsround online.

quiz, and take part in our vote

That's your lot for today.

Have a good one!
