Hawaii Weather Today » Glenn’s Daily Weather Narrative. Air Temperatures – The following high temperatures (F) were recorded across the state of Hawaii Tuesday. This webcam is available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars — and the sunrise and sunset too — depending upon weather conditions. Broad Brush Overview: A stable weather pattern is setting up over the islands. It looks likely that our Spring time weather will turn very nice. Light trade winds today will bring a few clouds and showers to windward sides. The winds may be light enough for some afternoon clouds and showers to develop over the leeward upcountry areas of the islands as well. High pressure building north of the state will increase trades to moderate levels Thursday into the weekend. This will return us to a more typical trade wind weather pattern. Marine environment details: A passing high pressure system far north of the Hawaiian Islands, will bring breezy trades across local waters beginning tonight. This will prompt a Small Craft Advisory (SCA) through at least Friday, for the typically windier waters around Maui County and the Big Island. Breezy trades will persist through Saturday.

Updated monthly to over 60 web sites. A small to moderate southerly swell will continue to lower over the next day or so. No significant swells from the south are expected through the weekend. North and west facing shores will be impacted by a series of northwest swells through early next week. A moderate north- northwest swell will spread across our waters Thursday, followed by a larger northwest swell late Saturday night and Sunday. Surf from this second swell will reach to near advisory levels for the north and west facing shores of Kauai Sunday night and Monday. A modest cooling trend will start Thursday, as an upper level trough approaches the coast. The cooling trend continues Friday into Saturday, when a slight chance of showers is forecast.
Locally windy conditions can also be expected over the weekend. Very warm to hot weather over the SF Bay area. That’s 4,0. 00 feet higher in elevation than the top of Wyoming’s Grand Teton. The road’s very remoteness has made it an international tourist attraction, drawing cyclists and adventurers keen on treading where so few have. Even here in one of the most distant corners of the planet, a place of desolate valleys and austere beauty, the researchers in UC’s Mc. Micken College of Arts and Sciences found evidence of pollution from diesel exhaust.“We measured incredibly high amounts of sulfur close to the highway. Some of those values are the highest ever reported in the literature and were likely connected to truck traffic,” Crowley said. The results were published in the journal Archives of Environmental Contamination and Toxicology. The research was funded through grants by the UC Research Council, Sigma Xi and the Oak Ridge Associated Universities. For the study, Dasgupta took soil samples at four places along the highway and at six prescribed distances, starting with samples literally on the dirt road and extending out 1. Soil samples were collected at 3, 9 and 1. Dasgupta said villagers in this area burn wood and cow dung for cooking and heating their homes. The resulting smoke often contains polycyclic aromatic hydrocarbons, a known carcinogen. They tested the soil for these hydrocarbons along with sulfur, total organic compound and 1.

The study found low levels of heavy metals and no relationship between their concentrations and distance from the highway. But they found high concentrations of sulfur, a major pollutant in the exhaust of diesel- powered engines.“This area provided us with a rare opportunity to examine the effects of multiple contaminants in a remote, diesel- dominated, mountainous environment,” Dasgupta said. Comparative studies have found that India’s diesel contains an especially high sulfur content, the UC researchers said. Sulfur dioxide in the atmosphere contributes to acid rain.“At first glance, it’s easy to consider the region to be a pretty pristine place. But there are environmental impacts from humans,” Crowley said. Last year India ratified the Paris Agreement on climate change. The world’s second- largest nation by population produces nearly 5 percent of the world’s greenhouse gases. The agreement calls for participating countries to develop a plan to address temperature rise. India has a goal of producing 4. Diesel fuel is popular in India because it historically cost drivers less there than regular unleaded. Most of the buses and heavy trucks that traverse the Manali- Leh Highway burn diesel fuel. Completed in the 1. Manali and Leh sees about 5. Himalaya means “abode of snow” in Sanskrit. UC researchers found the highest sulfur contents at the base of the narrow ridges that are most prone to rock slides. Trucks sometimes must wait to use a single lane while construction crews make repairs.“The road is terrible, and it’s almost always under construction. There can be lines of traffic idling waiting to go over the passes,” she said. You see black snow deposited on glaciers and snowfields in Tibet,” Owen said. Humans are the biggest geologic agents now. Some researchers are calling this geologic age . But Crowley’s scientific interests have taken her around the world. She has made four trips to Madagascar to study lemurs and reconstruct the causes and consequences of extinctions on the island. She and her students have examined the effects of sea spray on vegetation in Trinidad and looked at ways the first humans in the Canary Islands changed its ecology.“I’m a paleoecologist. I’m interested in human- animal interactions. I haven’t conducted pollution research previously, and this study with Rajarshi has stretched me in a new direction,” she said. Dasgupta said the study proved to be a learning experience for him as well.“This study was the first of its kind for me, too,” Dasgupta said. I study the evolution of the landforms around us. However, as a geographer, I have always been interested in the interactions of humans with the natural environment – the central theme of all geographic research. This study fits that theme perfectly.”In the Himalayas, the researchers found native wildlife such as ibex, herds of wild asses called kiang and condors, one of the largest birds on the planet. Adding to the bucolic scene, many of the villagers who live in the foothills tend goats.“It’s a beautiful landscape. The scale is hard to comprehend when you’re driving on a plain at 1. It takes a while to acclimatize to the elevation,” Crowley said. The night skies were full of stars in that sparsely inhabited part of India, with little moisture in the atmosphere to obscure the view. The arid mountains have little vegetation and lots of exposed strata of rock.“It’s a geologist’s dream. UC professors in geology have been conducting research and teaching classes in this region for many years,” she said. The researchers had to hire an experienced driver to take them over the mountains. They used a filtration system to provide clean drinking water. In some of the low- lying areas, they had to help push their truck out of the mud.“We’ve gotten a flat tire both times we’ve gone to India. You need nerves of steel to deal with the blind curves,” she said. Crowley said places on the extreme edges of habitability such as the Himalayas could be the first to feel the effects of dramatic climate change. These mountain ranges provide water and nutrients for rivers in India.“These are places that might have perennial glaciers that are important sources of water. If the glaciers disappear, that has major implications for people who rely on that water,” she said. The samples collected for this study provide baseline data if researchers decide to revisit the topic of roadside pollution in 1. And given her track record of travel for UC, Crowley might be the one leading that expedition, too.“One of the joys of being a professor is you have some freedom in the kinds of research questions you can explore,” she said.
