Monday Message Board

Another Message Board

Post comments on any topic. Civil discussion and no coarse language please. Side discussions and idees fixes to the sandpits, please.

I’ve moved my irregular email news from Mailchimp to Substack. You can read it here. You can also follow me on Mastodon here

I’m also trying out Substack as a blogging platform. For the moment, I’ll post both at this blog and on Substack.

  1. “A reversal in global terrestrial stilling and its implications for wind energy production

    “We illustrate that decadal-scale variations of near-surface wind are probably determined by internal decadal ocean–atmosphere oscillations, rather than by vegetation growth and/or urbanization as hypothesized previously.

    “The strengthening has increased potential wind energy by 17 ± 2% for 2010 to 2017, boosting the US wind power capacity factor by ~2.5% and explains half the increase in the US wind capacity factor since 2010. In the longer term, the use of ocean–atmosphere oscillations to anticipate future wind speeds could allow optimization of turbines for expected speeds during their productive life spans.”

  2. Ikonoclast,
    You may wish to check the BOM historical records for your locality/area of interest.
    Find the weather station nearest to your area (search by town/suburb/state, lat/long), then check the applicable records. Some general info is free, or if you are really keen you may wish to order more specific data from the BOM for a fee.

    Check out your area for risk for 2030, 2050, 2100 with high, medium or low emissions scenarios using the Climate Council Risk Map.

    As the air warms, it contains more energy and can hold more moisture content: 7% for each 1 °C of air temperature increase.

    As the ocean surface temperature warms tropical cyclones/hurricanes can be sustained at higher latitudes. 26 °C is the critical temperature threshold above which these high-energy intensity weather cells can form and sustain themselves.

    David Spratt & Ian Dunlop’s Climate Dominoes: Tipping Point risks for critical climate systems, published May 2022, included:

    Feedbacks can drive abrupt, non-linear change that is difficult to model and forecast, with the Earth moving to dramatically different conditions. Such changes may be irreversible on relevant time frames, such as the span of a few human generations. Major tipping points are interrelated and may cascade, so that interactions between them lower the critical temperature thresholds at which each tipping point is passed.
