Marine WindsHere’s the latest (automatically updated) weather map showing a 1026 millibar high pressure system to the northeast of Hawaii. A cold front is moving in our direction, which will push the ridge over the islands…slowing down our winds. Cooler, stronger north to northeast winds will arrive Sunday.

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 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 MountainsHere’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.

Inside the Haleakala Crater…on Maui





A weak cold stalled out before reaching Oahu Thursday, although allowed strengthening trade winds to envelop the island chain Friday…with a few windward biased showers. These trade winds however won’t last long, as the next cold front in line is already approaching from the northwest.  This IR satellite image shows what’s left of the retired frontal cloud band having retreated to the north of the islands…actually pushed there by the trade winds. This satellite picture also shows the relatively clear skies present over the Aloha state Friday afternoon. The atmosphere remains on the dry and stable side today, so that whatever showers that might be coaxed out of our stratocumulus and cumulus clouds…will be generally on the light side.

As we shift into the first part of the upcoming weekend, this next cold front will force our trade wind producing high pressure ridge southward over some parts of the island chain. This in turn will prompt lighter air, which will likely veer our local winds around to the southeast and south…perhaps even to the southwest around Kauai later in the day Saturday into the night. We may see some vog being carried up from the BigIsland vents in places Saturday. The Kona winds ahead of the cold front my pick up some strength on the Kauai end of the chain too.

As we move into Sunday, we’ll see some fairly dramatic weather changes, as the front’s precipitation shield pushes down through the islands…hopefully as far as the Big Island. The computer models had, as has been their habit this winter, shown a good rainfall event earlier this week. More recently though, it now looks like the rainfall can be de-emphasized to some degree, although there will be some showers quite assuredly during the day Sunday. We’re hoping that these showery clouds will make it down to Maui and the Big Island, where the most severe drought conditions in the state prevail at the moment.

The wind aspect of this cold front, and especially in the wake of its passage (fropa), will likely be the bigger event overall though. Let’s take a peek at this cold front, using the same satellite image as above, only with a broader perspective. We can see, at least at the time of this writing, a well pronounced leading edge…called in the weather business a rope cloud. While we’re checking out this active Pacific frontal boundary, here’s an even larger look, using a University of Washington image. This last image makes the cold front look quite impressive, along with a large area of high cirrus clouds to our far southeast.

Looking into the first day of the new work week ahead, it has windy written all over it…which may very well necessitate several different NWS issued wind products in response. It looks very likely that small craft wind advisories will be needed across the entire marine area, in terms of the coastal waters. There have been hints that the winds may become strong enough that we could actually see a fairly unusual gale warning flag being hoisted over a couple of the major channels between the islands. It wouldn’t be out of the question to see a wind advisory go up over one or three of the windiest land locations over the islands themselves. These too are fairly unusual, and definitely suggest that this windy episode will catch most folk’s attention.

Perhaps the windiest part of this event will be through Monday, with some gradually reduction in wind speeds Tuesday. The winds will come in first from the north, due to the following high pressure system, behind the cold front…being located to our northwest. As time moves on, this cool blast of air will turn clockwise to the northeast, and eventually all the way around to the ENE and east by mid-week. The models point out that this will be a longer lasting period of trade winds than we’ve been seeing so far this winter, which isn’t too unexpected climatologically… given that we’re pushing towards the start of the spring season a little ways ahead. As is often the case, we will see incoming showery clouds depositing moisture along our windward coasts and slopes…which will be very welcome due to the severely dry conditions that prevail now.











It’s Friday, as I begin writing the last section of today’s narrative.  If you had a chance to read down through the paragraphs above, you know that we have one more nice day coming up. There will be clouds around at times, which isn’t unusual. The main thing however is that our overlying atmosphere is dry and stable, which simply means that whatever clouds that around won’t be able to drop many showers. We’ll see a fairly big change as we push into Sunday, as this next cold front pushes down into the island chain. I’m hoping for some decent rains riding in with the frontal cloud band, although if things go as they have most of this winter…it may be somewhat disappointing. This front however does have a decent chance of moving over all the islands, which is a good thing. Likely though, this frontal passage will be remembered more for the strong and gusty winds following it, rather than the rainfall that falls from it. As always, time will tell, and I’ll be keeping close track of its behavior as it approaches, and then moves over us from the northwest Saturday night into Sunday.

~~~  I find it interesting, that as much as I was looking forward to getting back home here on Maui, after being on Oahu most of the work week…I miss Honolulu a bit! There’s something so engaging about being on that very active island, with its over 1 million people. I’m actually a little surprised that I have this feeling, although as I’m here on Maui for another day or two, I’m pretty sure it will fade.

~~~ I’m planning on going to see a new film this evening, one in which I told myself was too scary, and that I was going to give a pass. I had a close friend from California who I trust, tell me that it wasn’t all that confronting, so I’ll go give it a try. It’s called Shutter Island (2010), directed by Martin Scorsese…starring Leonardo DiCaprio















, Ben Kingsley, Mark Ruffalo, among others. A short synopsis: Two U.S. marshals, Teddy Daniels and Chuck Aule, are summoned to a remote and barren island off the coast of Massachusetts, to investigate the mysterious disappearance of a murderess from the island’s fortress-like hospital for the criminally insane. Again, as I’ve viewed the trailer, it looks pretty intense to me. Just in case you have any interest in taking a look, you can see what you think by clicking on this trailer











I just took another look at the trailer, in anticipation of seeing it tonight, and I must admit…this looks like it will be pushing me right to the edge of my bravery threshold!

~~~ I’ll be back Saturday morning with your next new weather narrative, and of course, if I make it through this film, my personal review. I hope you have a good Friday night until then! Aloha for now…Glenn.

Interesting: An iceberg the size of Luxembourg has broken off from a glacier in Antarctica after being rammed by another giant iceberg, scientists said on Friday, in an event that could affect ocean circulation patterns. The 965 square mile iceberg broke off earlier this month from the Mertz Glacier’s 100 miles floating tongue of ice that sticks out into the Southern Ocean. The collision has since halved the size of the tongue that drains ice from the vast East Antarctic ice sheet.

"The calving itself hasn’t been directly linked to climate change but it is related to the natural processes occurring on the ice sheet," said Rob Massom, a senior scientist at the Australian Antarctic Division and the Antarctic Climate and Ecosystems Cooperative Research Center in Hobart, Tasmania. Both organizations, along with French scientists, have been studying existing giant cracks in the ice tongue and monitored the bumper-car-like collision by the second iceberg, B-9B.

Interesting2: China has no intention of capping its greenhouse gas emissions even as authorities are committed to realizing the nation’s target to reduce carbon intensity through new policies and measures, the country’s top climate change negotiators said yesterday. The negotiators also warned that rich and developing countries have little hope of overcoming key disagreements over how to fight global warming.

China "could not and should not" set an upper limit on greenhouse gas emissions at the current phase, said Su Wei, the chief negotiator of China for climate change talks in Copenhagen, at a meeting in Beijing on China’s climate change policies in the post-Copenhagen era.

Su, who is also director of the department of combating climate change under the National Development and Reform Commission, said that China’s greenhouse gas emissions have to grow correspondingly as the country still has a long way to go in improving people’s livelihoods and eradicating poverty.

The country’s carbon dioxide emissions per capita is also relatively low compared to developed countries and China has not contributed much to climate change because of its short history as an industrial nation, he said. However, China will spare no effort to adopt proactive measures to fight the negative effects caused by global warming and achieve the country’s ambitious goal of cutting carbon intensity per GDP unit by 40 to 45 percent by 2020, a voluntary target China pledged last November, he said.

"The targets for carbon intensity reduction will be included in the 12th and 13th five-year plans (2011-15; 2016-20) as a binding index," he said. The targets remain a very challenging task for China, as its secondary industry comprises a large part of the country’s industrial structure, said Ma Zhong, a professor at the Renmin University of China.

Interesting3: The U.S. Fish and Wildlife Service is acting to remove Endangered Species Act protection from Arizona’s desert nesting bald eagles. Almost two years after U.S. District Court Judge Mary Murguia’s March 5, 2008 rejection of the agency’s last attempt in 2007, a similar decision by Fish and Wildlife has been released for publication in tomorrow’s Federal Register. Today the agency also filed a request with the U.S. District Court to remove an injunction currently in place to protect the eagle.

"We conclude that the best information available does not indicate that persistence in the ecosystem of the Sonoran Desert Area is important to the species as a whole," the new Fish and Wildlife decision states. But no recognized bald eagle expert agrees with that assertion, as no expert agreed with the Service’s earlier 2007 decision to remove protection. "The science and the law have not changed, but sadly, neither have the politics," says Dr. Robin Silver with the Center for Biological Diversity.

"If the decision stands, it will be a death sentence for our desert nesting bald eagles. We’re anxious to get back into court to save these magnificent birds." The desert nesting bald eagle is an icon of the Southwest’s desert rivers, and only about 50 breeding pairs survive.

The population is reproductively, geographically, biologically, and behaviorally distinct from all other bald eagle populations, since no other bald eagle population occupies habitat so hot and dry — an adaptation that’s critically important as global warming becomes increasingly problematic for species survival. No other population of bald eagles will move in if this population disappears, and that will result in a significant gap in the overall bald-eagle range.

Interesting4: The personal care industry has long demanded stricter standards for products labeled "natural," and in February, the Natural Products Association (NPA), the group representing retailers and manufacturers including Whole Foods and Clorox Co., has released new standards for home-care products. These include household cleaners for bathrooms and kitchen countertops and laundry detergents. Up until now, there has been no definition of the term "natural" within the home-care products industry.

Daniel Fabricant, NPA vice president of scientific and regulatory affairs, has been quoted as saying that many so-called natural cleaning products contain largely synthetic ingredients. And consumers are already confused about what makes products natural as well as organic. The Natural Certification Program and Seal of Approval was developed for products that meet the NPA’s new guidelines.

In May 2008, the NPA created standards and a seal for natural personal care products such as shampoos, moisturizers, and lotions. More than 340 products have been reviewed and have been certified by the NPA.

In order to display the Natural Home Care Seal, home-care product manufacturers must meet specific criteria, including making certain their products contain at least 95 percent truly natural ingredients derived from natural sources, with the exception of water. The products must not contain any ingredients that have any suspected health risks, such as residues of heavy metals or other ingredients not approved by the FDA or the EPA; or have any ingredients that adversely affect the natural ingredients.

Interesting5: Bees communicate their floral findings in order to recruit other worker bees of the hive to forage in the same area. There are two main hypotheses to explain how foragers recruit other workers; the "waggle dance" theory and the "odor plume" theory. The dance language theory is far more widely accepted, and has far more empirical support.

Honeybees do not only waggle dance to tell hive mates the whereabouts of good eats, they also bump and beep to warn others when big trouble awaits at some of those floral diners according to a recent study. In 1947, Karl von Frisch correlated the runs and turns of the dance to the distance and direction of the food source from the hive.

The orientation of the dance correlates to the relative position of the sun to the food source, and the length of the waggle portion of the run is correlated to the distance from the hive. Also, the more vigorous the display is, the better the food. There seem to be two types of dances: the circle for food less than 100 meters distant and the figure 8 for longer distances.

Now there is the discovery of the "stop" or warning signal as the first negative or "inhibitory" message ever found in bees. Previously the only recognized messages were all about how good and where the nectar was at various locations relative to hive. "Originally people called it a begging signal," said bee researcher James Nieh of the University of California at San Diego, regarding what was for 20 years considered a mysterious behavior.

"It’s usually produced by butting the head and giving a short beep" to another bee that is in the middle of providing information to the hive about a specific feeding site. Another researcher thought perhaps this had something to do with overcrowded feeding areas, said Nieh. But others saw the same behavior in un-crowded hives as well. "That got me thinking about what there could be in common.

What if they were being attacked?" So Nieh and his assistants devised a series of experiments to simulate attacks by predatory crab spiders or by bees from competing colonies. "In all causes we found yes, they all significantly increased ‘stop’ signals," Nieh confirmed. His results are reported in the February 23 issue of the journal Current Biology.

What’s more, the bees delivering the stop signals are not wasting time: They target the message directly at those bees that are trying to recruit for the specific locations where the attacks are happening, said Nieh. They do this, as their experiments confirmed, by identifying odors that the bees got from those specific locations, he explained.

Ants also have a similar "stop" signal. Pharaoh ant colonies can re-designate pheromone trails with a scent that says "Don’t follow this trail!" when the way is no longer safe or worthwhile. The negative signals the bees and ants brings them that much closer to operating exactly like a multi-cellular organisms which use positive and negative feedback signals all the time between cells.

Interesting6: The creation of marine protected areas can lead to the rapid recovery of depleted fish populations, according to several new studies presented at the annual meeting of the American Association for the Advancement of Science. One study, conducted in a network of 12 marine reserves covering 188 square miles near Los Angeles, showed that since the area was closed to fishing in 2003, heavily-fished species such as blue rockfish have increased by 50 percent.

A study of the Great Barrier Reef in Australia showed that when the Australian government increased the portion of the park closed to commercial fishing from 5 percent to 32 percent in 2003, the biomass of numerous fish species, including coral trout, doubled within two years. In Mexico’s heavily-fished Gulf of California, the creation of the Cabo Pulmo protected area at the southern tip of the Baja peninsula has created a flourishing area of marine life, according to one study.

Another study said that well-designed marine reserves can benefit fisheries outside of protected areas, since halting fishing in key spawning areas means that fertilized fish eggs can drift with sea currents and replenish populations far from reserves. The studies are published in a special issue of the Proceedings of the National Academy of Sciences.
