Speaker 1 (00:09):
It is time to catch up with Phil Duncan from
weather Watch. I found the right button eventually, Phil Duncan.
(00:38):
Good afternoon, How things nice work?
Speaker 2 (00:40):
Yeah, very good things. Good to be back with you
again on a beautiful end to the week.
Speaker 1 (00:46):
This weather has been pretty settled over the last few
days here in the South. I got cooler over the weekend.
Snow was experienced down to a couple of hundred meters
and places fell. Duncan, are we saying anything over the
next seven days to be aware of?
Speaker 2 (00:59):
I tell you what. If I look at the next
seven to ten days, looking just at the temperatures, it
looks to me like we are sliding out of winter
and sliding into early spring. That's what it looks like,
because you're still getting cold nights, especially tonight and tomorrow night.
There'll be minus twos, minus three's minus fours around northern Southland.
(01:21):
So some good frosts over the next couple of mornings.
But then as we go into Sunday Monday, we're sort
of creeping up above zero, and as we go through
next week, the overnight lows go up to four or
five even eight degrees, and then they do drop back again,
but only to two or three, So it's still kind
of cold at night, but not that bad. And the
daytime highs twelve degrees or so today thirteen or fourteen
(01:43):
by the time we get to Sunday Monday, and then
next week for a time fifteen's and sixteen seventeen maybe
possible by next Wednesday. Before next weekend things get colder again.
So what I look for when we go out of
winter and go into spring from a weather forecasting point
of view, seeing these little kind of like peaks in
the map. So whether that's a peak of temperatures where
(02:05):
it goes up into the mid to upper teams, or
it's a lack of frost for a period of time,
or maybe it's a peak of windy weather. And so
those are the things we're looking for to identify a
spring weather pattern. And when that turns up it changes
every year, but it does look a little bit spring like,
I've got to admit coming up over the next week
(02:27):
or so, as we start to get more Westia's back
in the weather forecast.
Speaker 1 (02:30):
So is it going to be a short sharp blast.
Speaker 2 (02:34):
It looks I wouldn't say sharp, it looks like well,
basically at the moment where we're going to see two
different things. At the moment, we've got a really powerful
high pressure zone ten thirty eight ten forty hector pascals
moving smackdang over the top of the South Island. So
that is you know, when the air pressure is that high,
it is using its elbows to push away any kind
(02:54):
of wet weather. So we don't really have anything significant
apart from isolated showers that is really in control of
our weather. But you fast forward seven days, that gigantic
area of high pressure is replaced by an even larger
area of low pressure. And it's not just one big low,
it's four or five lows that all kind of merge together.
(03:14):
And so when they're big, when a low is big
like that, the weather is not always severe, but it
does usually mean days of showers in the forecast. And
I do see an uptick and westerly winds, so temperature's
going up, westerly is coming in, low pressure increasing. That's
usually a bit of a sign that maybe we might
be changing seasons, although I'm always nervous saying that. But
(03:36):
I'm talking to people in Southland.
Speaker 1 (03:39):
Because it's been reasonably settled, and people we've talked about
this before being concerned about what September holds. But you reckon,
we just need to put every season into perspective.
Speaker 2 (03:49):
Every season is different, every season is unique. And even
though we do have a sort of a general time
of the year when our seasons change, because we're two
mountainous islands all out at sea on our own, things
can change very quickly. It's just the placement of high pressure.
So if high pressure is parked west of us, we're
more likely to have southerlys, If high pressure is north
(04:09):
of us, we're more likely to have westerlies, and if
high pressure is east of us, we're more likely to
have a warmer airflow. So these placement of high pressure
can can alter our weather pattern for half a month
at a time, and so that's the reason why our
seasons have different dates every year and when you kind
of feel that season changing. But what we're looking for
(04:31):
for September a little bit hard to lock in just yet,
but I know that we're almost there. But basically that's
because we've been in a neutral weather pattern for the
last year and a half and so we're having all
sorts of things thrown at us, but not necessarily a
lot of severe weather. And what I'm looking for is
is that westerly change coming next week with all that
low pressure, Is that it's a sign of the spring
(04:54):
westerlies arriving or is it just a blip in the winter?
Were the pattern that where we've been under?
Speaker 1 (04:59):
So do you know the high what does temperature ever
recorded on Earth? What do you reckon it was?
Speaker 2 (05:03):
Though? As in the shade or in the sun.
Speaker 1 (05:06):
Now in the sun, Oh, I'm guessing.
Speaker 2 (05:09):
Quite possibly one hundred degrees celsius maybe maybe not quite
that hot.
Speaker 1 (05:14):
Right, fifty six point seven degrees in Death Valley in
nineteen thirteen.
Speaker 2 (05:17):
That's the that'd be in the shade. Temperatures are usually
done in the shade about a meter above the ground.
I've been to Death Valley. I was in Death Valley
in October a few years ago, which is October is
their start of autumn, so it's kind of like our
March and or March year March April our men. And
it was thirty one degrees celsius and on a day
(05:41):
we had a frost that morning where we left only
just down the road, so that'd be like waking up
in Queenstown with a frost and then driving to Alexandra
and it's thirty degrees an hour and a half later.
It was quite surreal. That made you think, gosh, what's
it like there in the middle of summer.
Speaker 1 (05:56):
I always remember looking at the weather forecasts when I
was a younger for America, and I couldn't understand how
they just live in a hundred degrees not being aware
of fahrenheit versus celsius. And I just thought Americans are
just weird, full stuff if they can live in one
hundred degrees.
Speaker 2 (06:11):
I still find it hard getting my head around the
fahrenheit feet inches. You know, my my parents obviously they
measured in inches and feet when they were younger, and
so like that for them, it's it's not that hard work,
but it is. It's very difficult to add up numbers.
And you know, whereas the metric system is so easy
(06:31):
from a weather forecasting point of view, and it's just like,
you know, one hundred degrees is boiling, zero degrees is freezing.
It's all very clean and easy, whereas over there the numbers, yes,
thirty two degrees fahrenheit is freezing, and you know, it
gets very confusing. But once you're in it on, once
you're in America and you're using it. It doesn't take
very long before it all feels very normal and it
(06:53):
all makes sense.
Speaker 1 (06:54):
Metric versus imperial. We won't won't go into that today.
Feel doune and the look. We always appreciate your time.
Enjoy the week end.
Speaker 2 (07:00):
Cheers, mate, you two, Thank you.
Speaker 1 (07:02):
