Weather Chart – Here’s the latest (automatically updated) weather map showing two high pressure systems, one to the north, and the other far to the northeast of the islands. Our trade winds will be moderate, to locally strong and gusty Saturday and Sunday…lighter in those more protected places.
Satellite and Radar Images: To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with the Infrared Satellite Image of the islands to see all the clouds around the state during the day and night. This next image is one that gives close images of the islands only during the daytime hours, and is referred to as a Close-up visible image. This next image shows a larger view of the Pacific…giving perspective to the wider ranging cloud patterns in the Pacific Ocean. Finally, here’s a looping IR satellite image, making viewable the clouds around the islands 24 hours a day. To help you keep track of where any showers may be around the islands, here’s the latest animated radar image.
Hawaii’s Mountains – Here’s a link to the live webcam on the summit of near 14,000 foot Mauna Kea on the Big Island of Hawaii. The tallest peak on the island of Maui is the Haleakala Crater, which is near 10,000 feet in elevation. These two webcams are available during the daylight hours here in the islands…and when there’s a big moon rising just after sunset for an hour or two! Plus, during the nights and early mornings you will be able to see stars, and the sunrise too…depending upon weather conditions.

The trade winds slipped slightly in strength Friday, and may remain a little off their strongest mark Saturday…only to crank-up a notch again Sunday into the new week ahead. There’s two high pressure systems that are responsible for all this air in a hurry, one to the northeast, and the other to the north of the Hawaiian Islands Friday night…as shown on this weather map. The winds have eased back enough now, that the NWS office in Honolulu has active small craft wind advisories…only around Maui County and the Big Island. We will likely see a full set of small craft advisory flags springing up again later Saturday, covering Sunday onwards.
These locally gusty trade winds will continue to deposit off and on showers along our windward coasts and slopes…and over the lower mountains on the smaller islands Looking at this satellite image, we see that there is still a fair amount of high clouds down to to the south of our islands. They are slowly migrating northward over us, which will act to dim and filter our Hawaiian sunshine this weekend. At lower levels, there will be the usual passing showers, as noted above, along our windward sides generally. The leeward sides will be nice for the most part, although again with those high clouds back over us again now.
It’s early Friday evening here in Kihei, Maui, as I begin writing this last paragraph of today’s weather narrative from paradise. As discussed in the paragraph above, we have those high clouds around again now. If we look at this looping satellite image, we can see that they are destined to sweep over our islands again this weekend. At the time of this writing, they aren’t all that thick, but by Saturday, I’m quite sure they will be dimming and filtering our famous Hawaiian sunshine more extensively. ~~~ Meanwhile, the other weather condition that will be in our face, so to speak, will be the gusty trade winds. They have come off their peak strength today, and may remain slightly lighter again on Saturday…but will ramp up again Sunday onwards. All of next week will be filled with locally strong and gusty trade winds, so I suppose we had best be getting used to them being around for a while. ~~~ I’m ready to leave Kihei, at a little before 6pm, although not sure where the car will take me yet. I know that there’s are no new films that I’m interested in seeing tonight. So, I may turn the wheel left, or I might turn it right, who knows where I’ll end up! ~~~ The one thing that I am absolutely certain about however, is that I’ll be back Saturday morning with your next new weather narrative from paradise. I hope you have a great Friday night whatever you do, or wherever you’re spending it! Aloha for now…Glenn.
Interesting: Norma Wooley checked into Loyola University Hospital on a recent Monday morning for brain surgery to repair a life-threatening aneurysm. She went home on Tuesday, cured of the slurred speech, drooping face and worst headache of her life. Dr. John Whapham used a less-invasive technique that’s becoming increasingly common in brain surgery. The Loyola University Health System neurologist inserted a catheter (thin tube) in an artery in Wooley’s leg and guided it up to her brain. The catheter released tiny platinum coils into the bulging aneurysm, effectively sealing it off.
"She went home the next morning with a Band Aid on her leg," Whapham said. Whapham, 36, is part of a new generation of neurologists who are using catheters to repair aneurysms, open clogged arteries, extract blood clots and repair blood vessel malformations in the brain. He also opens blocked carotid arteries in the neck. The catheter technique is much less invasive and risky than traditional brain surgery, which involves cutting a large opening in the skull.
Catheter technology, originally developed for heart surgery, has been modified for narrower and more challenging blood vessels in the brain. "There has been a huge evolution in devices over the last five years," Whapham said. Whapham is an assistant professor in the Departments of Neurology and Neurological Surgery, Loyola University Chicago Stritch School of Medicine.
Interesting2: Scientists have pinned down the constituent of olive oil that gives greatest protection from heart attack and stroke. In a study of the major antioxidants in olive oil, Portuguese researchers showed that one, DHPEA-EDA, protects red blood cells from damage more than any other part of olive oil. "These findings provide the scientific basis for the clear health benefits that have been seen in people who have olive oil in their diet," says lead researcher Fatima Paiva-Martins, who works at the University of Porto.
Heart disease is caused partly by reactive oxygen, including free radicals, acting on LDL or "bad" cholesterol and resulting in hardening of the arteries. Red blood cells are particularly susceptible to oxidative damage because they are the body’s oxygen carriers.
In the study, published in Molecular Nutrition & Food Research, Paiva-Martins and colleagues compared the effects of four related polyphenolic compounds on red blood cells subjected to oxidative stress by a known free radical generating chemical.
DHPEA-EDA was the most effective and protected red blood cells even at low concentrations. The researchers say the study provides the first evidence that this compound is the major source of the health benefit associated with virgin olive oils, which contain increased levels of DHPEA-EDA compared to other oils.
In virgin olive oils, DHPEA-EDA may make up as much as half the total antioxidant component of the oil. Paiva-Martins says the findings could lead to the production of "functional" olive oils specifically designed to reduce the risk of heart disease.
Interesting3: Six out of every 10 university students, regardless their field of study, present symptoms of anxiety when it comes to dealing with mathematics, according to a research work carried out at the University of Granada in Spain. In addition, there are significant differences between men and women, with men suffering less anxiety when it comes to dealing with mathematical tasks (47% of men versus 62% of women).
The research has been carried out by professors Patricia Pérez-Tyteca, Enrique Castro, Isidoro Segovia, Encarnación Castro and Francisco Fernández, of the department of Didactics of Mathematics of the UGR, and Francisco Cano, of the department of Evolutionary and Education Psychology.
This study was carried out in a sample consisting of 885 first-year students from 23 different degrees given at the UGR which include the subject of mathematics, both compulsory and core. The sample included four of the five university fields of study: Health Sciences, Experimental Sciences, Technical Education and Social Sciences.
Interesting4: Is today’s academic and corporate culture stifling science’s risk-takers and stopping disruptive, revolutionary science from coming to the fore? In April’s Physics World the science writer Mark Buchanan looks at those who have shifted scientific paradigms and asks what we can do to make sure that those who have the potential to change our outlook on the world also have the opportunity to do so.
When Max Planck accidentally discovered quantum theory, he kick-started the most significant scientific revolution of the 20th century; his colleague, Wilhelm Röntgen’s experiments with cathode rays led inadvertently to the discovery of X-rays, which ultimately revolutionised modern medical practice; and US physicists at Bell Labs, Arno Penzias and Robert Wilson, detected cosmic wave background radiation — the echo of the Big Bang — when trying to get rid of the annoying noise being picked up by their microwave receiver.
Would today’s physicists, plagued by the publish-or-perish ethic, have the same freedom to explore their findings? Buchanan offers a selection of different perspectives in the article. He looks, for example, at suggestions that scientists themselves could take a financial risk in speculative research depending on whether they do or do not think it will pay off, as well as proposals – through, say, 10-year fellowships – that allow scientists to pursue really "hard", long-standing problems without the pressure for rapid results.
Interesting5: Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change. Researchers have found that dust blown south to Antarctica from the windy plains of Patagonia – and deposited in the ice periodically over 80,000 years – provides vital information about glacier activity. Scientists hope the findings will help them to better understand how the global climate has changed during the past ice age, and so help predict environmental changes in the future.
The study indicates that the ebb and flow of glaciers in the Chilean and Argentinian region is a rich source of information about past climates – which had not until now been fully appreciated by scientists. The study, carried out by the Universities of Edinburgh, Stirling and Lille, shows that the very coldest periods of the last ice age correspond with the dustiest periods in Antarctica’s past. During these times, glaciers in Patagonia were at their biggest and released their melt water, containing dust particles, on to barren windy plains, from where dust was blown to Antarctica.
When the glaciers retreated even slightly, their melt water ran into lakes at the edge of the ice, which trapped the dust, so that fewer particles were blown across the ocean to Antarctica. Dust from the ice cores was analysed and found to be a close match with mud of the same age in the Magellan Straits, showing that most of the dust originated in this region. The study was supported by the Natural Environment Research Council. The findings were published in Nature Geoscience.
Interesting6: Cell phone users don’t have it easy – many enter far more letters than numbers into their gadgets, but most phones still make you do so using a number pad. Meanwhile, the designers of smart phones seem determined to make touch screen keyboards the norm before they have been fully perfected.
Although touch screens are growing in popularity with designers, tapping at images of buttons on a small, slippery surface does not provide a good user experience. Figuring out better ways to input text on touch screens is important for more than just phones too, as they become common in other places like desktop computers, gaming devices and coffee tables.
Recently some more innovative ideas have shown where the future of mobile touch-screen text input may lie. One that launched recently is Shapewriter – already available for the iPhone and soon on other devices. It does away with the backwards-looking concept of pecking at images of keys on a glossy surface.
A qwerty layout is still shown, but the user draws over it to link up the letters of a word they wish to write. The company behind Shapewriter says it has evidence this can be significantly faster than even a conventional touch keyboard – although at first glance, the shapes you draw even for relatively simple words seem elaborate.
Another approach is to use a phone’s vibrate function to give an uncannily real illusion of using physical buttons. Stephen Brewster’s team at the University of Glasgow, UK, achieve the illusion with split-second pulses of vibrations chosen to provide sensations that feel like pressing a button, or shifting from key to key. Next week at the Computer Human Interaction 2009 conference in Boston, Massachusetts, the team will present results of user tests on a Nokia N800 Internet Tablet equipped with the technology.
The system uses the feedback to allow you to press harder on the screen for uppercase letters. Ultimately, though entering text may stop being a physical task. We reported last year on the first "voiceless phone call", placed using a neckband that makes it possible for someone to think words and have a computer read or type them out. The device detects and translates nerve signals sent by the brain to the vocal cords when we merely think about speaking a sound.
