~~~ Hawaii Weather Narrative ~~~



Our winds will become even softer as we move into the weekend…bringing muggy conditions. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a wind profiler of the central Pacific. We find high pressure systems well to the west-northwest and east-northeast of the state. At the same time, we find several low pressure systems at varying distances far to our northwest through northeast. Our winds will come in from the east to east-southeasterly directions, gradually become lighter this weekend into Monday. As this happens, we’re apt to see some distinct increase in volcanic haze locall, along with sultry conditions too. As a cold front approaches the state from the northwest early in the new week ahead, our winds will swing to the southeast to south preceding its arrival. We may see more volcanic haze moving over some parts of the state again then. As the front passes through, we’ll likely find a couple of days of brisk and cool northerly breezes following in its wake.

We’ll find a few showers falling…which will increase at times locally this weekend. A fairly stable air mass is over the state now, with just scattered showers expected in most areas. There continues to be a large patch of clouds near Kauai, which is dropping some showers over the ocean to the southwest of Kauai at the moment. As we get into the weekend, we should find a localized increase in showers arriving from the east-southeast, as a trough of low pressure makes our atmosphere more shower prone. At the same time, the lighter winds will likely spawn some afternoon showers, some heavy, over the interior sections as well. The longer range outlook continues to show a cold front sliding down into our area from the northwest towards the middle of next week…bringing rain to the state then. Thereafter, we should find a drying trend, albeit a little on the cool side, with an autumn feel to our air for several days, tropically speaking of course.

Tropical Storm 18E (Nora)…remains active in the eastern Pacific. Here’s a satellite image of this tropical storm, with the National Hurricane Center’s (NHC) graphical track map…along with what the computer models are showing. Tropical storm Nora is expected to strengthen further…becoming hurricane Nora in about two days. The good thing about this tropical cyclone, which we see by looking at the forecast track, is that it takes an abrupt turn towards the north and then northeast, well to our east…taking it away from our island chain. If this pans out as expected, our Hawaiian Islands would see no direct influence in terms of clouds, rain and wind. We may eventually see some rise in our surf along the east or southeast shores with time.

Friday Evening Film:  This is one of those films that will have some you rolling your eyes, on the other hand, some of you will be thinking…I gotta see this one right away! It’s called Sicario, starring Emily Blunt, Benicio Del Toro, Josh Brolin, Jon Bernthal, Jeffrey Donovan, Daniel Kaluuya, and Sarah Minnich…among many others. The synopsis: In the lawless border area stretching between the U.S. and Mexico, an idealistic FBI agent [Emily Blunt] is enlisted by an elite government task force official [Josh Brolin] to aid in the escalating war against drugs. Led by an enigmatic consultant with a questionable past [Benicio Del Toro], the team sets out on a clandestine journey forcing Kate to question everything that she believes in order to survive. / If you have ah hankering to see this rather hard core trailer…go ahead and click on the link (otherwise, maybe just leave well enough alone). It’s not actually all that bad, although, it’s certainly no walk in the park.

Sicario was one heavy weight film, no two ways about it! The three main actors, Blunt, Brolin, and Del Toro, were all incredible, just over the top great. The story centered around the drug war in Mexico, with riveting performances. This film had a constant sense of urgency and tension, with the music grounding it to earth…it had serious gravity! By the way, Sicario is slang for hitman in Mexico, and Benicio Del Toro played this role to the hilt! As one critic said: “Smart enough to challenge your views, yet not too cerebral to alienate the mainstream, Sicario is a thoroughly engrossing watch that dazzles visually and connects emotionally.” I had high expectations going in, and coming out…they were all met and then some! As for a grade, there’s only one that applies, this film hits the top of the chart, one of my favorites of the year!

Here on MauiIt’s 6am Friday morning with clear to partly cloudy skies in general…and very hazy as well – or is that smoke from an early morning sugar cane burn? There was a wonderful celestial display again this morning in the eastern horizon before sunrise. A new crescent moon with several planets located nearby…it was very unusual and lovely to see first thing in the morning! / It’s now going on 10am, under what has turned out to be mostly clear weather…although the haze remains in place.

Mid-afternoon, under clear to partly cloudy skies, and lots of thick volcanic haze (vog). If this vog wasn’t so thick, it would be a decent day otherwise, although all this haze brings the day down from perfect quite a bit. I see that the cumulus clouds stacking-up over the West Maui Mountains are more vertical than normal…trying to attain towering cumulus proportions at times. This of course indicates a destabilizing atmosphere, and as noted above, we’re headed into a more shower prone reality as we push into this weekend.

We’re into the early evening now, and I can feel the arrival of tropical moisture…it started to feel muggy this afternoon. The haze is still with us, and it wouldn’t surprise me if it sticks around, at least off and on, until a cold front arrives around the middle of next week. The cool and brisk northerly breezes, following in the wake of the frontal boundary…will ventilate it away then.

I’ll be back with many more updates on all of the above and below, I hope you have a great Friday night wherever you’re spending it! Aloha for now…Glenn.

Interesting: 
Study of China’s Yellow River yields unexpected information about the Earth’s climate history
– By meticulously examining sediments in China’s Yellow River, a Swedish-Chinese research group are showing that the history of tectonic and climate evolution on Earth may need to be rewritten. Their findings are published today in the highly reputed journal Nature Communications.

To reconstruct how the global climate and topography of the Earth’s surface have developed over millions of years, deposits of eroded land sediment transported by rivers to ocean depths are often used. This process is assumed to have been rapid and, by the same token, not to have resulted in any major storages of this sediment as large deposits along the way.

However, knowledge gaps and contradictory data in research to date are impeding an understanding of climate and landscape history. In an attempt to fill the gaps and reconcile the contradictions, the researchers have been investigating present-day and ancient sediment deposits in the world’s most sediment-rich river: the Yellow River in China.

The researchers, from Uppsala University (led by Dr. Thomas Stevens) and Lanzhou University (led by Dr. Junsheng Nie), China, analysed Yellow River sediment from source to sink and determined its mineral composition. They also determined the age of mineral grains of zircon, a very hard silicate mineral that is highly resistant to weathering.

Zircon ages serve as a unique fingerprint that yields information about the sources of these sediment residues from mountain chains, according to Thomas Stevens of Uppsala University’s Department of Earth Sciences, one of the principal authors of the study.

The Yellow River is believed to gain most of its sediment from wind-blown mineral dust deposits called loess, concentrated on the Chinese Loess Plateau. This plateau is the largest and one of the most important past climate archives on land, and also records past atmospheric dust activity: a major driver of climate change.

The scientists found that the composition of sediment from the Yellow River underwent radical change after passing the Chinese Loess Plateau. Contrary to their expectations, however, the windborne loess was not the main source of the sediment. Instead, they found that the Loess Plateau acts as a sink for Yellow River material eroded from the uplifting Tibetan plateau.

This finding completely changes our understanding of the origin of the Chinese Loess Plateau. It also demonstrates large scale sediment storage on land, which explains the previously contradictory findings in this area.

‘Our results suggest that a major change in the monsoon around 3.6 million years ago caused the onset of Yellow River drainage, accelerated erosion of the Tibetan plateau and drove loess deposition,’ Thomas Stevens writes.

Weathering of this eroded material also constitutes a further mechanism that may explain the reduced levels of atmospheric carbon dioxide at the beginning of the Ice Age. The researchers’ next step will be to compare terrestrial and marine records of erosion to gauge how far sediment storage on land has impacted the marine record.

‘Only then will we be able to assess the true rates of erosion and its effect on atmospheric CO2 and thus the climate in geologic time,’ says Stevens.
