Weather Chart – Here’s the latest (automatically updated) weather map showing a 1027 millibar high pressure system located north of Hawaii. Our local trade winds will remain active, blowing generally in the light to moderately strong range, although locally a bit stronger in those windiest areas.

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. 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.

There will be a slight softening of our local trade winds now, although they will remain active through the rest of this week. The winds are still strong enough that the NWS is keeping a small craft wind advisory active over those windiest areas from Molokai down through Maui, to the Big Island Tuesday night. The computer models show the trade winds continuing through this week, right on into next week. This weather map, shows two moderately strong 1026 millibar high pressure systems, located to the north of our islands…the source of our trade winds now. The winds are rather gusty atop the summits on the Big Island, where a NWS issued wind advisory remains in force for those near 14,000′ peaks.

We can expect a few windward showers, increasing some later this evening into Wednesday from Kauai to Maui…less on the Big Island. The leeward sides will be nice and sunny for the most part during the days, with generally dry conditions prevailing. Looking at satellite pictures, there’s an area of clouds being carried in our direction by the trade winds. This batch of clouds are part of an old cold front, which was active several days ago far to the northeast of Hawaii. We may see a second more modest increase in windward showers later on Thursday or Friday, due to the arrival of a shower enhancing upper level low pressure trough then.

As many of you know, I attended a Pacific Disaster Center organized Climate Conference at the East-West Center last week. It was an impressive group of professionals, many of which were the top climate scientists from around the world. The long and short of the discussions concluded that the planet Earth is in trouble on many fronts. The scope of the problem is so large, and daunting, that it’s very difficult to know where to begin finding a solution. Actually, what was discussed was finding small, localized solutions (going green is a good way of describing this) rather than trying to tackle the big problems as a whole. Looking specifically at the Hawaiian Islands, what we will likely find is a trend toward having more El Nino like weather patterns. El Nino manifests as dry weather here in Hawaii, which can lead to severe droughts…and at the same time, more frequent tropical storms and hurricanes during summer into the fall months. Thus, we need to plan for conserving water, and preparing for storms that bring strong winds, high waves, and of course flooding over the upcoming decades, that is…if things continue to go in the direction they’re going now in the world.

It’s early Tuesday evening here in Kihei, Maui, as I begin writing this last paragraph of today’s narrative. We’re in the dog days of August now, down here in the tropical latitudes of the north central Pacific. The days are on the hot side, especially near sea level. Fortunately, the trade winds continue to blow, bringing their cooling and refreshing relief from the heat. Tuesday was yet another very nice day, the kind of day that sun worshippers love!  It turned out to be about as normal a summer day as possible, just the way almost everyone who spent any time outside, could have wanted it. As noted above, satellite imagery shows an area of showery clouds moving into the windward sides of the islands…although the Big Island appears to be just out of reach of these showers. We can look for off and on showers into the night, and likely into Wednesday, which will go a long ways towards keeping our lush tropical vegetation watered. I’ll be back very early Wednesday morning with your next new weather narrative, I hope you have a great Tuesday night! Aloha for now…Glenn.

Hawaii has announced the results of its beverage container recycling efforts for the fiscal year 2008, and the state increased recycling by four percent to reach 72 percent recovery, an all-time high. The state says this means more than 680 million containers were recycled from July 1, 2007 to June 30, 2008. State law requires that if more than 70 percent of containers are recycled there would be an increase in the container recycling fee (this cover costs of collection and sorting), but the director of health decided to waive the fee increase (it’s currently one cent per container).  Hawaii is one of 11 states to offer a beverage container deposit, meaning consumers pay a fee (in this case six cents) when purchasing containers and get a refund when the containers are recycled.  Part of the increase may have to do with the expansion of Hawaii’s HI-5¢ program in 2007. See what your state is doing regarding recycling using Earth911’s Act Locally section.












Interesting2: The U.S. public, while aware of the deteriorating global environment, is concerned predominantly with local and national environmental issues, according to results from a recent survey. "The survey’s core result is that people care about their communities and express the desire to see government action taken toward local and national issues," said David Konisky, a policy research scholar with the Institute of Public Policy and assistant professor in the Truman School of Public Affairs at the University of Missouri, who conducted the study. "People are hesitant to support efforts concerning global issues even though they believe that environmental quality is poorer at the global level than at the local and national level.

This is surprising given the media attention that global warming has recently received and reflects the division of opinion about the severity of climate change."  Konisky recently surveyed 1,000 adults concerning their attitudes about the environment. The survey polled respondents about their levels of concern for the environment and preferences for government action to address a wide set of environmental issues.  A strong majority of the public expressed general concern about the environment. According to the survey, the top three issues that the public wants the government to address are protecting community drinking water, reducing pollution of U.S. rivers and lakes, and improving urban air pollution issues like smog. In the survey, global warming ranks eighth in importance.

The word "planet" has meant many different things over the millennia and even still its definition is evolving. The word is typically traced back to the ancient Greeks, who believed the Earth was stationary at the center of the universe while objects in the sky revolved around it. The Greek term asters planetai mean "wandering stars" and described the tiny lights that moved across the sky more dramatically than stars when compared over weeks and months. These wandering stars, back then, amounted to Mercury, Venus, Mars, Jupiter and Saturn. Some think the Greeks and Romans of ancient times considered the sun and Earth’s moon as planets.

An Elizabethan-era stage play and comedy published in 1597, called "The Woman in the Moon," depicted the solar system with seven planets, including Saturn, Jupiter, Mars, Mercury, Venus, Sol (the sun) and Luna (the moon). Nicolaus Copernicus, in 1543, published his mathematical evidence of a heliocentric universe where the six planets revolved around the sun. Only six planets, including Earth, were known until the 18th Century. In 1781, Sir William Herschel discovered Uranus in that he determined the point of light was a planet and not another star as it had been considered until then.

Dips in the sun’s activity have triggered centuries-long droughts in eastern North America, according to a new study that examined the geologic record stored within a stalagmite from a West Virginia cave. The link between periodic droughts and changes in solar activity initially was proposed by geologist Gerald Bond. He suggested that every 1,500 years, weak solar activity caused by fluctuations in the sun’s magnetic fields cooled the North Atlantic Ocean and created more icebergs and ice rafting, or the movement of sediment to the ocean floor. This caused less precipitation to fall, creating drought conditions. The climate record preserved by trace elements such as strontium, carbon and oxygen in stalagmites is clearer and more detailed than records previously taken from lake sediments. During dry periods, strontium is concentrated in stalagmites. Carbon isotopes also record drought because drier soils slow biological activity.

For the new study, researchers cut and polished a stalagmite taken from Buckeye Creek Cave, and drilled out 200 samples. The metals and isotopes in the stalagmites’ growth layers were weighed and analyzed to determine how the concentrations changed over time. The stalagmite’s record provides evidence that there were at least seven major droughts during the Holocene era in eastern North America. Some of these, from about 6,300 to 4,200 years ago, were particularly pronounced, lasting for decades or even entire centuries. "This really nails down the idea of solar influence on continental drought," said geologist Gregory Spring of Ohio University and the study’s leader. The results of the study are detailed online in the journal Geophysical Research Letters.
