Hawaii’s MountainsHere’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.

Glenn’s Monday comments:  I’m here at Sea Ranch, CA with my friend Bob.

It’s clear this morning here at the coast, although with some beautiful streaks of high icy cirrus clouds, which lit up a pretty pink at sunrise. The low temperature here was 51 degrees.

Hawaii’s Broad Brush Weather Overview: Breezy to locally strong trade winds will continue this week, as an increase in winds is expected by mid-week, with high pressure building north of the islands. Clouds and showers will remain focused over windward and mountains areas.

Hawaii’s Weather Details: Winds over the coastal waters are stronger than even the high resolution models had forecast, so additional adjustments were made to boost the wind forecast over our local waters. Over land, some isolated areas, mainly along and around mountain tops, are near wind advisory levels. Winds are expected to increase over the next couple of days, so confidence is increasing for some areas to fall under a wind advisory.

A band of showery clouds continues to remain focused over the windward sides of the islands from Oahu to the Big Island. The GOES-18 precipitable water sensor shows drier air moving into the islands from the north, so expect reduced shower activity as the day wears on. Global models suggest another increase in shower activity Tuesday night into Wednesday.

Dewpoints are expected to remain in the mid 60’s today and tomorrow, which will help to make it feel a touch cooler. Heading into Wednesday, as additional moisture rides in on the trades, expect dewpoints to increase into the upper 60’s to near 70. Trade winds look to peak Wednesday, and then subside to more moderate levels Thursday. Passing clouds and showers will continue to ride in on the trade winds.

Fire weather:  Critical fire weather conditions not expected the next couple of days. Breezy to locally strong trades will continue across the state through much of the week, but low-level moisture embedded within the trades should help to keep relative humidity from reaching critical thresholds.

Hawaii’s Marine Environment: A high will build far north of the state over the next couple of days, maintaining fresh to strong northeast trade winds over all marine zones. A Small Craft Advisory has been extended through Tuesday afternoon for all coastal marine zones, due to a combination of winds and high seas. The high will shift closer and northeast of the state Wednesday and Thursday strengthening the trade wind speeds to near-gale force over the windier waters and channels around Maui County and the Big Island.

A new large north-northeast swell (20 deg) is filling in locally and should peak just after daybreak. Offshore buoy 51000 appears to have peaked 2 to 3 feet above guidance, and is slowly flattening out. Peak surf heights have thus been increased a couple of feet to reflect this, but should stay within High Surf Advisory (HSA) criteria. The HSA will remain in effect through through Tuesday morning as this swell slowly fades, but could possibly be extended.

A Marine Weather Statement (MWS) also remains in effect due to potential harbor surges generated from this large swell within north facing harbors, such as Hilo and Kahului. The MWS may need to be extended through the middle of the week, but will be determined depending if this swell transitions to more of a northeast angle.

A moderate northwest swell is expected to fill in late Tuesday, and peak Wednesday near High Surf Advisory levels for north and potentially west facing shores. Another moderate to large, medium period northeast swell (40-50 deg) may be generated from a developing gale low pressure system to the northeast, which could keep north shore surf elevated through much of the week.

East facing shores will exhibit large rough choppy seas through the forecast period, with potentially the largest surf at High Surf Advisory levels during the middle of the week.

The first in a series of small, long period south swells is filling in. The next small long period south swell will fill in Tuesday and peak Wednesday before subsiding Thursday. These swells should keep modest surf along south facing shores through much of the week.

Interesting:  Climate Intervention Techniques Could Reduce the Nutritional Value of Crops, New Study Finds

A new study published in the journal, Environmental Research Letters, reports that cooling the planet by injecting sulfur dioxide into the stratosphere—a proposed climate intervention technique—could reduce the nutritional value of the world’s crops.

Scientists at Rutgers University used global climate and crop models to estimate how stratospheric aerosol intervention (SAI), one type of solar geoengineering, would impact the protein level of the world’s four major food crops, maize, rice, wheat and soybeans. The SAI approach, inspired by volcanic eruptions, would involve releasing sulfur dioxide into the stratosphere. This gas would transform into sulfuric acid particles, forming a persistent cloud in the upper atmosphere that reflects a small part of the Sun’s radiation, thereby cooling the Earth.

While these cereal crops are primarily sources of carbohydrates, they also provide a substantial share of dietary protein for large portions of the global population. Model simulations suggested that increased CO2 concentrations tended to reduce the protein content of all four crops, while increased temperatures tended to increase the protein content of crops. Because SAI would stop temperatures from increasing, the CO2 effect would not be countered by warming, and protein would decrease relative to a warmer world without SAI.
