Bounce Out

---

The Met Office has recently introduced an upgrade for its existing supercomputer (image) announced. But even more money for the computer would be welcome, says Prof Palmer

A top climate scientist has called for more investment in climate-computing, the UK's recent topsy turvy Weather .

Professor Tim Palmer of Oxford University, said there were still too many unknowns in the climate forecasts.

And in the month, the SpaceX launch grabbed headlines, he is only One of The Firm said could transform a billion-climate-modeling.

short-term Weather forecast is generally very accurate.

And long-term trends in rising temperatures is not in doubt.

But the Prof says Palmer, many puzzles remain unsolved: take the recent topsy-turvy Weather in the UK, with the wettest February On Record , followed by the sunniest spring.

Weather Salto

forecasters were astonished at this unprecedented Weather Salto – and, above all, by the astonishing amount of

This year, the figure was 13% higher than the previous Record – this is how The Winner of The 100 Meter opponents left 13 meters behind.

says Some point the blame on human-caused Climate Change , But the Met Office , So Far there is no strong evidence for this.

Prof Palmer told Bbc News : “It would be really valuable for us to know more about how Climate Change is affecting Weather patterns.

“climate change's involvement in the recent strange Weather ? We don't know it. "

The Met Office said. February 2020, as the wettest February On Record

He agrees That space observations have solid our understanding of the climate improves.

But he complains: “It is very frustrating to see the place get quite as much attention, if we can't be sure what will happen to the climate on The Earth .

“If only we could,

So, what do we know So Far about the last of the British Weather craziness?

But many questions are still are unsure: take the recent topsy turvy Weather in the UK, with the wettest February On Record , followed by the sunniest spring.

Jetstream locked

Now, here is what is locked out clear: the strong jetstream in the South West of England through The Winter , the succession of Atlantic storms, the wet, and the UK.

The Met Office predict wet winter, said in its seasonal forecast, But not to the prediction of the sudden jump to a dry spring, when the jetstream was looped over the UK, instead of stopping the Sunny Weather .

In a global climate-chicken-and-egg debate about the question of why the jet stream has behaved in this way.

Some scientists believe, it is influenced by the conditions in The Arctic , which is warming faster than anywhere on The Planet , because of greenhouse gases. But this is controversial.

Prof Palmer the jet stream is said to be affected appeared by a climate phenomenon called The Indian dipole, an irregular oscillating flow in the Indian Ocean . This Was also the blame for the forest fires in Australia.

But what is the influence of The Indian dipole is? Or is it completely natural?

the scientists know the sea currents on The Other side of The World can have an impact on our Weather and warm waters around the Chagos Archipelago really prompt a “Grill-spring“ in grateful lockdown the UK?

"It is very strange things in the tropics are added," Prof Palmer. “The question is, ‘is it natural?' and

the scientists are now planning to re-run the UK's climate models over the last few years and remove the heating element from the CO2 emissions from the Mathematical Puzzle . The should have a better understanding of the British Weather , at least.

Unlock the secrets

Prof to Palmer, it is not surprising, the exercise was earlier done. But all of the uses of extra money for climate research, he thinks That most of it could be useful to the expenditures for climate research, to unlock the mystery of the Clouds – One of The Most difficult climate-secrets.

When warmer Weather leads to more low-level Clouds is to cool the bounce radiation, and The Earth . If it leads to more high-level Clouds That will trap in the heat.

In fact, Prof Palmer said, a last cloud modeling exercise suggested That , if we have bad luck, the global temperatures to rise by 5C after CO2 levels are doubled – One level, the completely inhospitable for humans. The conclusion was previously excluded under a different analysis.

"We need to understand these processes better," he says.

“Usually in science you learn about The System under study-by-doing experiments in the laboratory. With the climate of The Earth , there is no laboratory experiment you can do.

“The climate model is the only tool we have to understand what the future holds in store for humanity as a result of Climate Change .

“Space observations tell us what is Happening Now , But climate models tell us what will happen next year, next decade, next Century . "
