Prediction time as the 2021 season approaches. The expected impacts of El Niño and La Niña on hurricane seasons in both the Atlantic and Pacific ocean areas are discussed by NOAA here. Hurricane detection has improved over time, so what is considered ‘average’ now is unlikely to be the same as it used to be.

The year 2020 saw the most active hurricane season on record and marked the fifth consecutive year for above-average activity, says Phys.org.

A University of Arizona-led hurricane forecasting team predicts another year of above-average hurricane activity over the Atlantic Ocean in 2021.

The team predicts 18 named storms, including eight hurricanes, throughout the 2021 North Atlantic hurricane season, which runs from June 1 to Nov. 30.

In comparison, the 30-year average is 13 named storms and seven hurricanes annually.

Four storms are expected to produce major hurricanes, which are defined as category 3, 4 or 5.

If the predictions are realized, 2021 will be the sixth-consecutive year for above-average activity.

“The past decade has been very active for hurricanes,” said forecast creator Xubin Zeng, director of the university’s Climate Dynamics and Hydrometeorology Center and a professor of atmospheric sciences.

“We need to ask ourselves if this is part of the natural variability of the system, or if we are already seeing impacts of global warming,” said Zeng, who is also the Agnes N. Haury Endowed Chair in Environment in the Department of Hydrology and Atmospheric Sciences. “If this is part of the natural variability, then after some overactive seasons, we’d expect activity to quiet down, but every year is kind of crazy in the past few years.”

While Zeng expects that a warming world is translating to warmer ocean waters that fuel hurricane development, that can’t yet be confirmed through modeling.

“In climate modeling, every model resolution (similar to a single pixel or grid box on the Earth’s surface) is about 50 miles by 50 miles. In contrast, for global weather forecasting models, the resolution is more like five miles by five miles,” Zeng said. “If we really want to simulate the impact of global warming on hurricanes, it’s preferable we have the smaller model grid box, and we just don’t have the computing power for that yet for decade-long simulations.”

Zeng predicts, however, that in another 10 years, he will have the data and confidence to say for sure that the increase in hurricane activity was outside of the natural variability of the climate.

While this season is expected to bring above-average activity, it isn’t expected to be as dramatic as last year, partly due to average climate patterns in the Pacific Ocean driven by sea surface temperatures.

When eastern tropical Pacific sea surface temperatures are below average—a weather phenomenon known as La Niña—it drives up easterly wind speeds over the Atlantic that exacerbate hurricanes.

When Pacific sea surface temperatures are above average—a weather pattern referred to as El Niño—it weakens easterly winds and weakens hurricane activity over the Atlantic.

A diet of daily assertions that human-caused carbon dioxide emissions are a big deal, isn’t evidence of anything.

A paper published today shows that attempts to blame extreme weather on human-caused global warming are “overconfident and probably wrong”, says The Global Warming Policy Forum.

The paper, by statistician and philosopher of science Dr William M Briggs, reveals that mainstream attribution science is beset by flaws of reasoning, modelling and data.

Spain renewables

Findings:

  • The prospects for a sustainable, low-carbon economy as the result of current UK national and EU-wide policies are poor.
  • Empirical experience in Spain and Germany shows that the costs of supporting renewable energy generation are too high.
  • Rising employment in the renewable energy sector compared to the wider UK economy stems from unsustainably high subsidies.
  • Renewables are naturally less productive, so as they are relentlessly pursued, a painful rebalancing of the economy will occur, with fewer jobs and less economic growth.

What drives the weather can drive the climate. In this case the chances of non-correlation are said to be extremely low.

—–

A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth, Phys.org reports.

If the connection outlined in the journal Earth and Space Science holds up, it could significantly improve the predictability of the largest El Nino and La Nina events, which have a number of seasonal climate effects over land.

For example, the southern United States tends to be warmer and drier during a La Nina, while the northern U.S. tends to be colder and wetter.

“Energy from the Sun is the major driver of our entire Earth system and makes life on Earth possible,” said Scott McIntosh, a scientist at the National Center for Atmospheric Research (NCAR) and co-author of the paper.

But that’s not the whole story. It seems from long-term data ‘that these super-cold thunderstorms may be increasing in frequency. There have been as many such events across the globe in the past three years as there were in the 13 years before that.’ Could this be in some way related to the big decline in sunspot activity over the last two solar cycles?

We’ve all seen those majestic anvil storm clouds that form on a hot summer’s day, but what do you think is the temperature right at the very top? – asks BBC News.

It’s very cold, obviously; at high altitude it is well below freezing.

But would you be surprised to learn it is sometimes below even -100C?

Indeed, scientists have just published research showing the top of one tropical storm cloud system in 2018 reached -111C. This is very likely a record low temperature.

Severe river floods are escalating in temperate climates and putting at risk populations, livelihoods and property, according to evidence published today in Geophysical Research Letters by an Oxford-led international team, says Phys.org.

The first global examination of recent changes in the size, frequency, and probability of extreme river floods using historical river records, the paper shows that dangers of extreme river flooding demand close monitoring of rivers for decades to come, to understand and account for the potential impact of such changes.

This week debates have heated up about the world’s shift away from fossil fuels, as frigid temperatures have wreaked havoc from Turkey to Texas, says PEI.

Let’s start in the USA. It’s the first time in 17 years that such a large portion of the US has been covered with snow and rolling blackouts have meant many have been without power, exposed to freezing temperatures.

Utilities are struggling to keep the power on as wind turbines have frozen and natural gas flow was impeded from frozen pipes.

According to USA Today: “In Texas, more than 1.6 million homes and businesses remained without power late Wednesday night, and some also lost water service”.

As is the case in many emergency situations, folks are looking for someone or something to blame. This time, the focus is on failing renewables – like the frozen turbines – with people questioning the shift from coal and natural gas, viewing it as unwise and risking baseload reliability.

(Bloomberg) — Millions of households in Texas are suffering rolling power blackouts for the first time in a decade as an unprecedented Arctic freeze wrought chaos in U.S. energy markets, reports Yahoo News.

The largest cities from Houston to San Antonio were without power for spells of up to an hour at a time as supplies in the U.S.’s second largest state fluctuated wildly.

“Every grid operator and every electric company is fighting to restore power right now,” said Bill Magness President and Chief Executive Officer of Ercot, the operator of the state’s power grid.

The extreme cold caught the highly decentralized Texan electricity market by surprise despite a heads up a week ago about the impending frigid temperatures from the U.S. National Weather Service.

Of course the WMO doesn’t miss the chance to promote its ‘human-caused warming’ dogma, painting La Nina is a minor break in their imagined process.

The 2020-2021 La Nina phenomenon has passed its peak, the UN weather agency said Tuesday, but its impact on temperatures, rain and storm patterns is set to continue, reports Phys.org.

The 2020-2021 La Nina phenomenon has passed its peak, the UN weather agency said Tuesday, but its impact on temperatures, rain and storm patterns is set to continue.

La Nina refers to the large-scale cooling of surface temperatures in the central and eastern equatorial Pacific Ocean, occurring every two to seven years.

The effect has widespread impacts on weather around the world—typically the opposite impacts to the El Nino warming phase in the Southern Oscillation cycle.

Besides the cooling effect, La Nina is usually associated with wetter conditions in some parts of the world, and drier conditions in others.

La Nina conditions have been in place since August-September 2020, according to atmospheric and oceanic indicators.

“La Nina appears to have peaked in October-November as a moderate strength event,” said the World Meteorological Organization (WMO).

The WMO said there was a 65 percent likelihood that La Nina will persist during February-April. The odds shift rapidly thereafter, with a 70 percent chance that the tropical Pacific will return to neutral conditions in the cycle by April-June.

“El Nino and La Nina are major drivers of the Earth’s climate system,” said WMO Secretary-General Petteri Taalas.

“But all naturally-occurring climate events now take place in the context of human-induced climate change, which is increasing global temperatures, exacerbating extreme weather, impacting seasonal rainfall patterns and complicating disaster prevention and management.”

The temporary global cooling effects of La Nina were not enough to prevent 2020 from being one of the three warmest years on record.
