Marine Winds – Here’s the latest (automatically updated) weather map showing a large high pressure system far north-northeast of the islands. Our local winds will remain generally light from the trade wind direction both Monday and Tuesday.
Satellite and Radar Images: To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with this Infrared Satellite Image of the islands to see all the clouds around 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.
Tropical Cyclone activity in the eastern and central Pacific – Here’s the latest weather information coming out of the National Hurricane Center, covering the eastern north Pacific. You can find the latest tropical cyclone information for the central north Pacific (where Hawaii is located) by clicking on this link to the Central Pacific Hurricane Center. Here’s a tracking map covering both the eastern and central Pacific Ocean. A satellite image, which shows the entire ocean area between Hawaii and the Mexican coast…can be found here. Of course, as we know, our hurricane season won't end until November 31st here in the central Pacific.
Aloha Paragraphs
Returning trade winds…good weather continuing
Artist: Jim Wilcox
Light easterly trade winds will gradually fill back into our Hawaiian Island weather picture…picking up strength into the new week ahead. The computer models continue to suggest that the trade winds will become light to moderately strong through mid-week. Later in the week, the trade winds will strengthen further, becoming moderately strong or more. This will likely lead to small craft wind advisories going up over those windiest areas around Maui County and the Big Island…by Thanksgiving for several days.
Winds around the state remain generally light…with the following numbers representing the strongest gusts Sunday evening:
20 mph Port Allen, Kauai
14 Waianae, Oahu
20 Molokai
21 Kahoolawe
21 Maalaea Bay, Maui
05 Lanai Airport
07 Honokaa, Big Island
The overlying atmosphere remains stable and dry, with fine weather expected into the new week…with increased windward precipitation during the second half of the week. This IR satellite image shows lots of clouds to the east of the state, where a trough of low pressure resides. If we look at an even larger view, using this next satellite picture, we can see abundant clouds from far northwest to the east. Meanwhile, this looping radar image shows that there are only a few showers around, being carried along in the light easterly trade wind flow.
It's Sunday evening as I begin writing this last section of today's narrative update. The weather today was just fine, starting off in a mostly clear way, and ending up that way too. The continued light trade winds, combined with the daytime heating of the islands, will probably allow more afternoon clouds around the mountains. The beaches should remain generally nice through the days. All those clouds to the east of the Big Island, and to the west of Kauai too, are impressive. The computer models are suggesting that we could see wet trade winds developing during the second half of the new week.
~~~ Here in Kula, Maui, at around 515pm, the air temperature was 67.6F degrees. Skies were clear to partly cloudy, with no wind to speak of. I expect tonight to be fair, with little change through mid-week. By the way, you'll notice that that big near full moon is still shining down brightly, and is worth taking a peek out the window before retiring, or upon rising in the morning. I'll be back early Monday morning with your next new weather narrative from paradise. I hope you have a great Sunday night until then! Aloha for now…Glenn.
Interesting: Comets are temporary night flashes across the sky. They are rarer than meteors and are further away. The EPOXI mission's recent encounter with comet Hartley 2 provided the first images clear enough for scientists to link jets of dust and gas with specific surface features.
The EPOXI mission spacecraft revealed a cometary snow storm created by carbon dioxide jets spewing out tons of golf-ball to basketball-sized fluffy ice particles from the peanut-shaped comet's rocky ends. At the same time, a different process was causing water vapor to escape from the comet's smooth mid-section.
This information sheds new light on the nature of comets and even planets. A comet is an icy small Solar System body that, when close enough to the Sun, displays a visible coma (a thin, fuzzy, temporary atmosphere) and sometimes also a tail. These phenomena are both due to the effects of solar radiation and the solar wind upon the nucleus of the comet.
Comet nuclei are themselves loose collections of ice, dust, and small rocky particles, ranging from a few hundred meters to tens of kilometers across. Scientists compared the new observed data to data from a comet the spacecraft previously visited that was somewhat different from Hartley 2.
In 2005, the spacecraft successfully released an impactor into the path of comet Tempel 1, while observing it during a flyby. The mission yielded results suggesting that the majority of a comet's water ice is below the surface, and that these reservoirs feed the jets of vaporized water that form the coma of Tempel 1.
"This is the first time we've ever seen individual chunks of ice in the cloud around a comet or jets definitively powered by carbon dioxide gas," said Michael A'Hearn, principal investigator for the spacecraft at the University of Maryland. "We looked for, but didn't see, such ice particles around comet Tempel 1."
The new findings show Hartley 2 acts differently than Tempel 1 or the three other comets with nuclei imaged by spacecraft. Carbon dioxide appears to be a key to understanding Hartley 2 and explains why the smooth and rough areas scientists saw respond differently to solar heating, and have different mechanisms by which water escapes from the comet's interior.
"When we first saw all the specks surrounding the nucleus, our mouths dropped," said Pete Schultz, EPOXI mission co-investigator at Brown University. "Stereo images reveal there are snowballs in front and behind the nucleus, making it look like a scene in one of those crystal snow globes."
Data show the smooth area of comet Hartley 2 looks and behaves like most of the surface of comet Tempel 1, with water evaporating below the surface and percolating out through the dust. However, the rough areas of Hartley 2, with carbon dioxide jets spraying out ice particles, are very different.
"The carbon dioxide jets blast out water ice from specific locations in the rough areas resulting in a cloud of ice and snow," said Jessica Sunshine, EPOXI deputy principal investigator at the University of Maryland.
"Underneath the smooth middle area, water ice turns into water vapor that flows through the porous material, with the result that close to the comet in this area we see a lot of water vapor." As might be expected every comet will be different though some similarities will occur.
Interesting2: You might think that politicians have enough on their plates trying to fix the economy, fighting wars in Iraq and Afghanistan, dealing with humanitarian crises in Haiti and Pakistan, and other matters of national import. But money talks, especially in politics, and a tiny bug is causing a big ruckus on Capitol Hill.
Today, Members of Congress, representatives from federal agencies, academic bed bug experts, the National Pest Management Association (NPMA), other industries and victims of bed bug infestations will gather at the Capitol Visitor Center in Washington, D.C. to participate in the "Don't Let Bed Bugs Bite" Congressional Forum organized by Representative G.K. Butterfield (D-NC).
The event, sponsored by the National Pest Management Association (NPMA), "will offer insights from the professional pest control industry about the extent of the bed bug problem, what the industry is doing to combat it and what the federal government can do to assist Americans whose lives are impacted by this pest."
How serious is the bed bug problem? The situation is dire, according to Missy Henriksen, vice president of public affairs for the NPMA: "Bed bugs are no longer a pest of the past or characters in a nursery rhyme, rather they are a real and serious problem. They have invaded not only residences, but public places as well. While our industry is committed to effectively eliminating the bed bug problem, federal intervention is also necessary. This Forum is a crucial first step."
Interesting3: When one imagines a squid, the image that comes to mind is of a giant monster (i.e, Kraken of mythic fame) grappling with boats and whales. Squid are marine cephalopods of the order Teuthida, which comprises around 300 species. Like all other cephalopods, squid have a distinct head, bilateral symmetry, a mantle, and arms.
Squid, like cuttlefish, have eight arms arranged in pairs and two, usually longer, tentacles. Squid are strong swimmers and certain species can 'fly' for short distances out of the water. Some are giant and some are tenaciously small.
An expedition to the seamounts of the southern Indian Ocean has proven that the region is a biodiverse hotspot for squids. To date, the expedition has identified 70 species of squid comprising 20% of the world's known squid species. But that's not all: they have also uncovered new species.
The majority of squids are no more than 24 inches long, although the giant squid may reach over forty feet in length. In 1978, sharp, curved claws on the suction cups of squid tentacles cut up the rubber coating on the hull of the USS Stein. The size suggested the largest squid known at the time.
In 2003, a large specimen of an abundant species, Mesonychoteuthis hamiltoni (the Colossal Squid), was discovered. This species may grow to 46 feet in length, making it the largest invertebrate. Squid have the largest eyes in the animal kingdom. Giant squid are featured in literature and folklore with a frightening connotation.
The Kraken is a legendary tentacled monster possibly based on the sightings of real giant squid. They are, in many ways, the epitome of what an alien creature should look like. At just over 2 feet long (27 inches), a species of squid found by the new Indian seamount expedition proves to be a brand new member of the chiroteuthid family.
Squids from this family, which number around a dozen known species, employ bioluminescent organs to attract unwary prey. Undertaken last year, the International Union for the Conservation of Nature (IUCN) expedition spent six weeks searching in the Indian Ocean.
Now, researchers are busy sorting out the 7,000 samples. There are many other isolated seamounts in the oceans of the world. Each one could help represent its own unique set of squids and other marine creatures.
Interesting4: The Chevrolet Volt plug-in electric car, the centerpiece of a revitalized General Motors Co, was named 2011 Green Car of the Year on Thursday. The highly anticipated Volt received the industry's top environmental honor the same day GM shares began trading — the biggest U.S. IPO ever.
The Volt edged out the Nissan Leaf and three other gas-sipping cars for the prize, which is awarded by Green Car Journal. "With the Volt we are making a bold pronouncement," said Joel Ewanick, GM's marketing chief, who accepted the award for the company.
"We need to be more aware of CO2 and fuel efficiency and it's a great start, but we're many, many years away from making that leap to where we need to be." Winning Green Car of the Year is yet another feather in the cap of the recovering 102-year-old automaker, which went from near-death in 2008 to a 2009 government bailout and bankruptcy to 2010 unlikely Wall Street flotation favorite.
General Motors' Volt, which its makers have touted as the symbol of a leaner and greener U.S. auto industry, is designed to run on electric power for about 40 miles, at which point it relies on a gasoline engine to charge the battery. The Nissan Motor Co Ltd Leaf is a plug-in that runs fully on electric power.
The Leaf will, on full charge, run for 100 miles or so, depending on road and weather conditions. Other finalists for the award included Ford Motor Co's new Fiesta, which can achieve 40 miles per gallon in highway driving. It was the only finalist not to use electric drive. Two hybrids, the Hyundai Motor Co Sonata Hybrid and Ford's Lincoln MKZ Hybrid, were also in the running.
