High and dry


From NASA’s Earth Observatory: yesterday’s Image Of The Day (RSS feed) was this stunning picture of an intense high pressure system over the Great Australian Bight to the southwest of Tasmania, acquired by the MODIS sensor on the Aqua satellite on June 5th. In high pressure systems, dry descending air suppresses cloud formation, in this case punching an impressive “hole” through a layer of stratocumulus clouds. Central pressure at the time was 1040 hectoPascals. According to the NZ MetService 7 day forecast, over the next week the system will move east and set up camp to the southwest of the South Island.

Also from the Aqua satellite last week, a good picture of the midweek snowstorm that hit the South Island. Thursday morning chez nous was as pretty as several pictures.

The climate terroirist – Gladstones’ new bag

Regular listeners to The Climate Show will know that I often witter on about what I’ve been up to in my little vineyard. At Limestone Hills we grow pinot noir and syrah grapes and make small quantities of wine. It’s more than drinkable. One day it may even be very good. If we get that far, it will be because our back paddock has an interesting terroir (and because we will have worked hard). It will therefore come as no surprise that I follow how the wine business approaches climate change with more than passing interest. A few days ago a local winemaker blogged about a new book. Wine, Terroir and Climate Change by Aussie scientist Dr John Gladstones, noting that Gladstones was “sceptical about the degree of climate change that will occur and thus the degree of effect on terroir“. Unsurprisingly, the usual suspects have rushed to welcome a new member to their ranks. I decided to do a little digging… Continue reading “The climate terroirist – Gladstones’ new bag”
