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 Weather Narrative ~~~

 

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.

We drove up to the small community of Point Arena this morning, and got some coffee and a chocolate cookies, and walked out on the pier…lots of high cirrus and warmer than usual temperatures.

We met some folks playing Pickleball here at Sea Ranch, and ended up playing 6-games…which was very fun!

Yet another great colorful sunset this evening!

Hawaii’s Broad Brush Weather Overview: Breezy to locally strong trade winds will continue this week, becoming even stronger by mid-week, as strong high pressure builds north of the islands. Clouds and showers will remain focused over windward and mountain areas.

Hawaii’s Weather Details: The latest surface analysis shows a 1031 millibar high far north of the Hawaiian Islands. This is resulting in breezy to strong trade winds blowing across the islands, with some of the windier areas on the Big Island and Maui briefly exceeding wind advisory criteria. Trades are expected to become even stronger by Wednesday as the high is forecast to build to around 1035 millibars. Confidence that more widespread areas will exceed wind advisory criteria on Wednesday is increasing…stay tuned for further updates. Winds will weaken to moderate to breezy later this week as the high weakens and moves northeast of our area.

Radar and satellite imagery continues to show clouds and passing showers focused over windward and mountain areas. CIMSS PWATs show a slightly drier air mass over and upstream of the area, so don’t look for a lot of showers across the region tonight. Guidance continues to suggest an increase in shower activity on Wednesday, as an area of moisture associated with a dissipating front gets embedded in the trade wind flow. Expect windward and mountain showers to continue through the rest of the week.

A slightly drier air mass will keep dew points in the low to mid 60’s through Tuesday, making things feel cooler than normal. Relative humidity may briefly fall below 50 percent on Tuesday afternoon for isolated leeward areas, particularly across leeward Big Island. Additional areas of moisture moving into the state later this week will allow dew points to increase to the upper 60’s to low 70’s.

Fire weather:  Breezy to locally strong trades will continue across the state through the week. Relative humidity may briefly fall into the upper 40’s on Tuesday for isolated leeward areas, but low-level moisture embedded within the trades should prevent this from being widespread. Additional areas of moisture moving into the state should help to keep relative humidity from reaching critical thresholds for the remainder of the week.

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.
