Transcript

00:00Hi, welcome to ABRICAST. Kirsten Dipprose here and Jane Barn is with us. She's a meteorologist,

00:13weather presenter and of course has Jane's weather. Welcome to ABRICAST.

00:18Very lovely to be here. Thank you.

00:21Summer's approaching. What does that mean in terms of the Pacific Ocean and how that

00:25might influence the climate?

00:27Well, at this time of year, we do like to look at what's happening in the Pacific Ocean

00:31because it can have a big impact on what our day-to-day weather ends up being in terms

00:35of how much rain we have and whether we have heatwaves. Over on our side of the ocean,

00:40we end up getting all this moisture pushed towards us. So it means as we go into this

00:44summer, we'll have extra moisture to play with. Now that's just part one of the rainfall

00:49equation. We need to have moisture. We also have to have instability, but that tells us

00:53that we're going to have extra moisture available. So when we do get those rain systems

00:57moving through, they could have heavier rain than we're used to.

01:00Does that mean La Nina for us or for other parts of the world?

01:04That is the big million dollar question. So there are global agencies. Australia is one

01:10of them. The US is another. It's a big player in this field. And as we're heading into summer,

01:15it looks like we're heading towards that La Nina threshold. Now I say towards because

01:20Some may say, yes, we're crossing it. Others may go, no, we haven't quite reached it yet.

01:25And the difference here is the US has a different threshold to what Australia has. This summer,

01:31we're likely to see at least some La Nina effects, i.e. all that extra moisture being

01:35pushed towards us.

01:36We had La Nina. It was a bit confusing for some people. We had rain in parts and then

01:42not in others. You look forward a lot, but do you ever look back and kind of assess just

01:47what, what the hell happened?

01:49It's nice to look back so you can go, okay, because that, that and that happened, we ended

01:53up with this particular situation. Now think back to last summer, we actually had the Tasman

01:58Sea that was incredibly warmer than average. And so that became the new source of moisture.

02:03So instead of the Pacific taking that moisture away, the Tasman delivered it and delivered

02:08it to large parts of the country. In terms of a normal year, now there is all this extra

02:13energy that's available in the atmosphere. It's got to go somewhere. So it has effects

02:17and highs are stronger and bigger and they last longer. Now cold fronts as they come

02:21through can be stronger or they're shifted southwards or they're shifted further north.

02:25When things come through, they have a bigger impact than what they used to do. When the

02:29extremes come in, you notice them more because they've got more power behind them. Now, as

02:34we get into it, the day to day nitty gritty, what's happening hour by hour, am I in the

02:38path of these thunderstorms or am I missing out because I'm on the other side of the trough?

02:43Have a look at that sort of thing. At Jane's Weather, that's exactly what we do. We have

02:47the best of the modelling. You can put your weather station in there and we can make it

02:51hyper local to your conditions and then help you unpack. It's not just a standard forecast.

02:57It's how you can use that decision making about what you've got to do on the farm today.

03:00Jane, thank you so much for joining us on ABRICAST. We'll speak to you soon.
