Lenticular clouds

A couple of days ago, Big Island skies were graced by lenticular clouds. These kinds of clouds are uncommon in Hawaii, but strong winds blowing up against Mauna Kea and Mauna Loa created perfect conditions.

Lenticular clouds appear to hover in one spot, but while they don’t move, they can change shape constantly. These two clouds behaved quite differently. The one on the right retained its basic shape all day. The one on the left was constantly morphing from one shape to another. Alas, I only got these photos because I was working and to photograph the clouds without an array of wires in the foreground meant a walk down the road a ways.

These clouds look like they’re close to the ground, but they form in the troposphere, between 6,500 and 20,000 feet. By the end of the day, the cloud on the left was largely broken up and disappearing, but the one on the right was still going strong, albeit while becoming masked by lower level clouds.

Crossing the line

The current eruption at Kilauea has been putting out a considerable amount of vog. This volcanic haze can make life difficult for people, causing respiratory and other medical complications. But it can also cause colorful skies.

I was driving home from work last week on a day when the vog was heavy and the sky glowed. There wasn’t much wind – another reason the vog has been hanging around – so the ocean was calm. I’d stopped to take photos once, but when I saw this little boat heading for this band of sunlight, I pulled over again.

I’d lucked into a quiet break in the traffic and was far enough from the coast that there was no sound from waves coming ashore or from the boat’s engine. I watched for a while until the boat crossed the glittering band, before returning to my car and heading home.

White Christmas in Hawaii

Season’s greetings to everyone. As one would expect, we’re having a white Christmas here on the Big Island. The storm of last week dumped a generous amount of snow on top of Mauna Kea and Mauna Loa and much of it is still around. It’s a lovely sight, especially when viewed from somewhere where the temperature is in the 70s or low 80s!

Moon over Mauna Kea

A sliver of moon rises over Mauna Kea, Hawaii

A couple of days ago, I saw this sliver of a moon rising over Mauna Kea. I didn’t have my tripod, so wedged myself as still as possible against a van. The close up shows that technique isn’t perfect, but still kind of interesting.

Sunrise over Mauna Kea

The morning I first saw Mauna Loa’s latest eruption (here), the sunrise was equally spectacular.

Cloud over Mauna Loa eruption

On my way to work yesterday, I pulled over to photograph this view of Mauna Loa, early on day three of the current eruption. The heat and emissions from volcanic eruptions can create their own weather. Here, smoke and gasses from the most active vent can be seen rising up into a cloud over the northeast slope of the volcano.

Mauna Loa erupts

Yesterday, my morning commute was enlivened by the sight of Mauna Loa erupting. The eruption started late Sunday night and the report I read, before leaving home, said the eruption was currently confined to the summit crater. That clearly wasn’t the case when I took these photos on the way to work. The quality isn’t great because they’re hand-held, but I think they illustrate the scene reasonably well.

In the top two photos, the red smoke is the glow of the lava, but the white/yellow bits are the lava itself. This was a flow moving down the slope of the volcano.

By the time I got to work, the sky was lightening but the lava still stood out. In the bottom photo, Mauna Kea is left center, with a stunning sunrise developing behind it. Mauna Loa is on the right and the activity can clearly be seen on the left (northeast) slope of the volcano, some way down from the summit.

When I got home, I read that three vents had opened on the northeast rift zone of the volcano, though only one was still active. Flows from Mauna Loa can reach the ocean in a matter of hours, depending on where they’re coming from and going to. This flow is currently heading towards the saddle between Mauna Kea and Mauna Loa, which is mostly a military training area and undeveloped land. The main current danger is from gasses and Pele’s hair, thin strands of brittle volcanic glass, being carried from the volcano to communities downwind. However, new vents could open farther down the rift, bringing lava closer to human habitation.

Changes in eruptions on Mauna Loa can happen pretty quickly so, as usual, the advice here is be prepared and keep tuned to updates on the situation.
