Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. 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 my friend Linda’s place in Corte Madera, CA

Good day everyone, I hope you have a great Monday wherever you happen to be spending it.

405am, it’s a clear morning, with a low temperature of 45 degrees.

1022am, like all the days recently, northern CA continues to have great weather conditions! Here along the coast, just north of San Francisco, the cool breeze coming off the ocean is maintaining the delightful weather!

 

Hawaii’s Broad Brush Weather Overview:  Moderate trades will prevail over the eastern islands through the first half of the work week, while lighter trades over the western islands allow for some leeward land and sea breezes. Relatively dry weather will persist through Tuesday, with a few showers affecting windward areas overnight into the early morning hours and developing over interior and leeward areas each afternoon.

The trade winds will rebound Tuesday night and Wednesday, bringing a transition over to a more typical trade wind weather pattern. The trade winds will become breezy Thursday through next weekend, and the trade wind showers may increase as well, due to a low pressure disturbance aloft moving over the island chain.

Hawaii’s Weather Details:  Weather maps show a weakening cold front west-northwest of Kauai, while a high is centered far northeast of Hawaii. Moderate trade winds prevail in unsheltered areas over the eastern end of the state, while lighter trades persist over the western islands. Satellite imagery shows a combination of high and low clouds resulting in mostly cloudy conditions across the state.

The front northwest of the islands will weaken into a trough, and edge slowly eastward during the next couple of days. Little change is expected in the overall wind forecast, with moderate trades holding on over the eastern end of the state, while lighter trades prevail over the western islands, allowing some leeward sea and land breezes to develop.

We should see the trades start to rebound beginning Tuesday night as the trough west of the state begins to shift slowly westward. Moderate to locally breezy trades should overspread the island chain by late Wednesday, with the trades becoming breezy Thursday through the weekend.

Meanwhile, relatively dry conditions should generally prevail across the island chain through Tuesday. Brief passing showers will be possible in windward areas overnight into the early morning hours, with a few showers developing over interior and leeward areas each afternoon. A few showers could be a bit more robust over Kauai and potentially Oahu this afternoon, as some energy grazes by just to the north.

We should see a transition over to more typical trade wind weather Tuesday night and Wednesday, with wetter trade wind conditions potentially developing Friday through the weekend, as an upper level low pressure system sets up over the state of Hawaii.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map

Marine Environmental Details: High pressure far northeast of the state will continue to slide east, while a weak dissipating cold front to the northwest, edges slowly eastward. Winds will ease through Tuesday and the Small Craft Advisory has been cancelled for all waters.

By mid-week, high pressure will rebuild to the northeast, transitioning us back to typically fresh to locally strong trade winds. The SCA will likely go back up for the typical windy waters around Maui County and the Big Island.

North facing shores will remain small through the week, with tiny to small background energy. Surf along east facing shores will continue to decline as winds begin to taper off through Tuesday. A small south-southwest pulse will fill in, peak Tuesday and ease Wednesday for south facing shores. Surf heights along the south facing shores should remain near or slightly below seasonal norms.

Interesting: How Do Birds Flock? Researchers Do the Math to Reveal Previously Unknown Aerodynamic Phenomenon

 

In looking up at the sky during these early weeks of spring, you may very well see a flock of birds moving in unison as they migrate north. But how do these creatures fly in such a coordinated and seemingly effortless fashion?

Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians in a newly published study. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.

“This area of research is important since animals are known to take advantage of the flows, such as of air or water, left by other members of a group to save on the energy needed to move or to reduce drag or resistance,” explains Leif Ristroph, an associate professor at New York University’s Courant Institute of Mathematical Sciences and the senior author of the paper, which appears in the journal Nature Communications.

“Our work may also have applications in transportation—like efficient propulsion through air or water—and energy, such as more effectively harvesting power from wind, water currents, or waves.”
