Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are 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.

Hawaii’s Broad Brush Weather Overview: A trough associated with the dissipated cold front northwest of Kauai will continue to drift northwestward away from the islands. The high pressure ridge will build back in from the north through the afternoon hours, with winds shifting from a more easterly direction.

A brief period of enhanced showers will develop over each island as these breezy trade winds return. The next round of enhanced showers will move in from the north, along a cold front, from Thursday night through at least Friday. Some of these enhanced cloud and shower trends may linger into early Saturday. Drier island weather trends from Sunday to next Monday.

Hawaii’s Weather Details: Satellite imagery appears rather cloudy this morning, as the subtropical jet stream spreads an abundance of high level cirrus and mid level altocumulus clouds across the entire state. In the low levels a weakening trough, associated with a dissipated cold front, northwest of Kauai will continue to lift northwestward away from the islands. This diminishing trough will allow the high pressure ridge to build back into the islands from the north.

The current east-southeasterly wind regime will be swiftly replaced by moderate to breezy easterly winds. A cloud band likely produced by the convergence of these stronger easterly winds will slowly move into the eastern or windward slopes of the Big Island. Expect this cloud band to drift westward throughout the day, briefly enhancing clouds and showers as it passes through each island. This cloud band moves through the Big Island and Maui this morning, reaching Molokai and Oahu around noon, and finally passing through the western islands of Kauai and Niihau through the afternoon hours.

High pressure aloft will produce stable conditions and keep fair weather in the forecast from New Year’s Eve through New Years Day, with only brief passing showers, mainly over windward and mountain areas in the overnight to early morning time periods. Moderate to locally breezy easterly trade winds will continue to blow through New Year’s day, keeping the fireworks smoke from settling in.

Another round of enhanced showers will move in from the north, along a cold front Thursday night through at least Friday. These cloud and shower trends from this frontal band may linger into early Saturday for some areas. Weather model solutions are uncertain on the ending of this period of enhanced shower activity. The American (GFS) model shows the frontal band stalling over the islands, a longer duration wet trade wind solution. While the European (ECMWF) model builds a stronger high pressure system just north of the state, driving this frontal band quickly through the region, a shorter duration and drier solution. Drier island weather trends should return across the region from Sunday into early next week.

Hawaii’s Marine Environment: Moderate to locally strong easterly trade winds return to the coastal waters and will continue through the week, as high pressure builds north of the islands. A Small Craft Advisory remains in effect for the typically windy waters around Maui County and the Big Island, and has been extended in time through Wednesday afternoon.

Overlapping moderate to large, medium period northwest (320-340 degree) and north-northwest (340-350 degree) swells will maintain advisory-level surf with very minor fluctuations through Wednesday. Recent buoy observations show that this swell is running around 2 feet above guidance at this time, so the High Surf Advisory for north and west facing shores of Niihau, Kauai, Oahu, Molokai, and north facing shores of Maui has been extended it in time through the day on Wednesday. This swell will then gradually decline from late Wednesday through the rest of the week, with surf falling back below advisory criteria at that time. Additionally, seas could flirt with Small Craft Advisory criteria across exposed waters during the peak of the swell.

Choppy east shore surf will continue though mid-week as locally breezy trade winds strengthen. Surf along south facing shores will remain tiny to small through the forecast period.

Interesting:  How Climate Policies that Incentivize and Penalize Can Drive the Clean Energy Transition

A new study from a team of researchers that includes faculty from the University of California San Diego and Princeton University shows how a mix of subsidies for clean energy and taxes on pollution can significantly reduce greenhouse gas emissions that cause climate change.

While these kinds of policy mixes are widely used in the real world, the the study, published in Nature Climate Change is the first to show how the combination of such policies can be simulated in economic models that are the backbone of nearly all climate policy discussions – including the recent United Nations Climate Change Conference in Brazil.

The results reveal that financial incentives can spark rapid adoption of cleaner technologies in the near term, but without policies that also punish polluters it won’t be possible to stop climate change.
