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 Wednesday comments:  I’m here in Corte Madera, Marin County, California, at my friend Linda’s on a working vacation.

I fly back to Maui this morning. I must say that I’ll miss being here, although I look forward to being back home, and seeing all my friends again.

Weather Wit of the day:  Rainbow – A remarkable display of colors that is always bent on disappearing

 

Hawaii’s Broad Brush Weather Overview:  Light east-southeast winds will favor a hybrid sea breeze pattern this afternoon, with clouds and showers developing over leeward and sheltered areas. Light to moderate easterly trade winds return by tonight, with moderate to locally breezy trades expected Friday into early next week. With stable trade wind conditions returning expect clouds and showers to favor windward and mountain areas.

Hawaii’s Weather Details:  Light east-southeasterly flow continue across the state, with a weak surface trough north of Kauai and surface high pressure far northeast of the islands. Radar and satellite imagery shows scattered clouds and showers mainly over the coastal waters, with a few showers occasionally moving onshore at times.

The latest hi-res guidance continues to show a hybrid sea breeze pattern developing across the state this afternoon. This will result in clouds and showers developing over leeward and sheltered areas, with western portions of the smaller islands being the most likely areas to see some enhanced convection this afternoon and evening. Also, due to light flow, expect vog to remain in place over portions of the state today.

Today will also serve as a transition day as light to moderate easterly trades gradually build across the state by tonight, as the surface trough dissipates to our west. This will allow drier air to slowly filter in from the east. The airmass will also gradually become more stable as an upper-level trough continues to shift eastward and weaken, allowing a mid-level ridge to build over the region. As trades become reestablished across the state later today expect vog to slowly shift away from the smaller islands.

Moderate to locally breezy trades are expected to return Friday then hold through early next week, as a pair of strong high pressure systems move north of the state. Expect showers to favor windward and mountain areas, particularly during the overnight and early morning hours.

Hawaii’s Marine Environment:  Trade winds with more stable weather conditions will build back in, strengthening to Small Craft Advisory levels for the typical windier coastal waters around Maui and the Big Island by Thursday.

A small northwest swell will continue to slowly fade, allowing surf along north and west facing shores to remain near or below average levels for this time of year. By Thursday, a moderate to long period north-northwest swell is expected to arrive, producing surf above the seasonal average. This north-northwest swell will slowly decline over the weekend.

Multiple small south swells will keep elevated south shore surf heights into the weekend. Trade winds should strengthen through Friday, with rough and choppy surf rising along east facing shores by this weekend.

Interesting:  Geoengineering Technique Could Cool Planet Using Existing Aircraft

A technique to cool the planet, in which particles are added to the atmosphere to reflect sunlight, would not require developing special aircraft but could be achieved using existing large planes, according to a new modelling study led by UCL researchers.

Previously, most research has assumed that the technique, known as stratospheric aerosol injection, would be deployed in the tropics and so would require specially designed aircraft capable of flying at altitudes of 20km or more to inject the particles.

For the new study, published in the journal Earth’s Future, scientists ran simulations of different aerosol injection strategies and concluded that adding particles 13km above the polar regions could meaningfully cool the planet, albeit much less effectively than at higher altitudes closer to the equator. Commercial jets such as the Boeing 777F could reach this altitude.

Lead author Alistair Duffey, a PhD student at UCL’s Department of Earth Sciences, said: “Solar geoengineering comes with serious risks and much more research is needed to understand its impacts. However, our study suggests that it is easier to cool the planet with this particular intervention than we thought. This has implications for how quickly stratospheric aerosol injection could be started and by who.
