Hawaii’s MountainsHere’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.

Aloha Paragraphs

Our cool northeasterly winds will be strengthening into the
weekend, bringing fair weather conditions, with just the
usual passing windward showers through the rest of this week

Small Craft Wind Advisory…all coastal and channel waters

High Surf Advisory…north and east shores of all the main
Hawaiian Islands except Lanai and Kahoolawe

Happy Thanksgiving!

~~~ Hawaii Weather Narrative

The trade winds will continue to strengthen over the next few days. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find a moderately strong, near 1027 millibar high pressure system to the northwest…which will be moving into the area north of our islands. At the same time, we have gale low pressure systems to the north and northeast, with an associated cold front still evident over the waters east of the Big Island. Gusty northeast winds will continue to move over the islands…strengthening Thanksgiving into the weekend.

Despite the stable stratocumulus clouds banked up against our windward sides, along with some light showers or drizzle locally…shower activity will be limited elsewhere. Here’s the looping radar image showing a few showers still falling in our area…most of those are light and occurring along our northeast facing slopes. As the winds continue from the northeast, we’ll see a trade wind weather pattern remain well established…with stronger and gusty conditions. Small craft wind warnings have now been extended to all marine zones around the state…continuing into the weekend. The leeward sides of the islands will have generally fair weather, with passing showers increasing modestly along our windward sides beginning Friday into Saturday morning. The latest computer model output shows no new cold fronts, or rainy episodes arriving through early next week. However, we may see a weak cold front slipping into our area by around next Wednesday. I’ll be back with updates on all of the above, I hope you have a great Wednesday night wherever you happen to be spending it! Aloha for now…Glenn.

Interesting: Climate change, species extinctions and tipping points - Researchers from North Carolina State University have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population’s adaptive strategy, even tiny changes in climate variability can create a “tipping point” that sends the population into extinction.

Carlos Botero, postdoctoral fellow with the Initiative on Biological Complexity and the Southeast Climate Science Center at NC State and assistant professor of biology at Washington State University, wanted to find out how diverse populations of organisms might cope with quickly changing, less predictable climate variations.

“Organisms tend to adopt a strategy for dealing with changes in their environment,” Botero says. “Some of them adjust their gene expression either at birth or throughout their lifetime, which we refer to as irreversible and reversible plasticity. Some do what we call ‘bet-hedging,’ producing offspring that are adapted to one of two possible outcomes so that at least half of their offspring survive, and some rely on plain old evolution – which we call adaptive tracking – to keep up with environmental changes. We wanted to determine which strategies worked best under certain circumstances, and find the point at which that strategy would no longer be viable.”

Botero and colleagues Franz Weissing from the University of Groningen, Netherlands, Jonathan Wright from the Norwegian University of Science and Technology and Dustin Rubenstein from Columbia University, created virtual organisms that were able to modify their insulation – or how they might respond to temperature changes through coat thickness, sweating, etc. – to adapt to the environment, and then placed them in simulations with areas of fast and slow temperature variation and high and low predictability.

The results mapped to a series of “zones” where each adaptive strategy worked best. For example, organisms that used reversible plasticity as a strategy did better in a highly predictable environment, even if the rate of environmental change was rapid. Organisms that relied on adaptive tracking, however, did fine regardless of predictability, as long as the rate of change was slow.
