On the latest episode of the BBC World Service’s Fishing Forecast podcast, which is recorded on BBC iPlayer, the presenter John Lister explains how a record cold winter is likely to impact on fisheries.
What you need to know about the polar vortex The polar vortex is the whirlpool of air that creates a polar vortex, creating the north-south vortex.
The vortex is generated when the surface air masses move over the surface of the Earth.
It has been predicted by scientists to produce an effect on sea surface temperatures of around 5°C.
“That means if you’re in the Northern Hemisphere, you will see a lot of higher than normal temperatures in the Arctic and the Antarctic,” he says.
“In the southern hemisphere, the polar jet will create a vortex, as well.”
The polar jet has a strong negative influence on the sea surface temperature, meaning higher temperatures are predicted for areas in the South Pacific, which has been particularly hard hit by the recent El Niño event.
At the same time, the jet will cause colder sea surface and ocean temperatures to prevail over areas of the Southern Hemisphere, and vice versa.
How the polar system works In order to understand how the polar region works, you need a little background on what it is, and what it does.
During El Niño, a strong La Niña is in effect, meaning there is more moisture in the air.
This moisture is what helps to keep the Arctic ocean warm, which in turn is good for fishing.
El Niño is also a long-term phenomenon, meaning that it lasts for decades.
But as El Niño progresses, the Pacific Ocean will become drier and colder, causing the polar regions to warm up, which means they are more likely to produce a polar jet.
This in turn will lead to warmer temperatures in some parts of the northern hemisphere, which are favourable for the production of polar jets.
“We see the effects of El Niño and La Niño as they are moving through the Northern and Southern hemispheres and that means the jet is creating a whirl and we’re going to see a polar region that will be more likely than ever to be able to produce the polar jets,” Lister says.
In the Northern hemisphere, that means colder weather in the north and south.
In the Southern hemisphere, warmer weather in both the north as well as the south.
Lister says this is what causes an increase in the amount of the polar-sphere vortex, which will create an upward trend in sea surface heat, and an increase of temperatures.
For example, in the southern part of the Northern Caribbean, the average temperature in October is expected to be 0.9°C (1.6°F) higher than in October 2017.
“We’ve had an El Niño in the Southern Caribbean since late October,” he explains.
“It’s a really cold region and we have seen the effect of El Niños in the Caribbean and the Northern Gulf of Mexico and we’ve seen a huge increase in sea ice in the North Atlantic.”
That’s the effect that El Niño has on the jet.
“The polar vortex has been linked to record-high temperatures in many areas around the world.
How to help the polar fishery What can you do to help?
If you’re fishing, it’s better to get out and catch your own fish,” he advises.””
Don’t go fishing unless you have your gear on.
If you’re fishing, it’s better to get out and catch your own fish,” he advises.”
If you’re on a boat you have to get your boat out to sea and be prepared to be on a lot more ice.
It will be a long season.””
You have to look after your own gear,” he adds.
“I would advise people to get off of boats when the polar sea ice is high, as the ice can be a problem.”
A new research paper published by the Arctic Research Centre in the journal Polar Biology warns that even if we can avoid a polar-induced record high, a record low sea surface will still be possible.
Researchers from the University of St Andrews in Scotland and the Arctic Ocean Research Centre, in Norway, have calculated the amount that sea surface water will be able open in the northern and southern hemispaces by the end of 2021.
They say that the amount will be similar to the amount previously recorded, but will be significantly lower than the previous record high of 2.3 million sq km.
The researchers also predict that the polar water can increase the risk of collisions between ice and ocean due to the increase in ocean currents that could lead to a surge in currents.
There are also a number of things that you can do to try and help the fish.
There are a number, including:Keeping out of the water.
“A lot of fish will have been caught in this event and we will be seeing a lot fewer of them,” Listers
