9.45 am, looking east, wind from south-west, 19°C: This altocumulus cloud has formed as a layer, so it is classified as stratiformis. The ripples mean that it’s also undulatus and, finally, because the sun is visible through the cloud, it’s translucidus.

10.30 am: Three-quarters of an hour later the sky has filled with stratocumulus. We don’t get thunderstorms but there are a few rain showers later in the day.

As you might have guessed, my current bedtime reading is Clouds by Eric M. Wilcox.

  1. That sounds like interesting bedtime reading. I’ll look out for a copy. A really useful tree guide for Australia has been on my list for ages too. I have a couple but it’s not the same as knowing the trees from familiarity I feel. Always lots of interesting things on your blog Richard and I always have a look for your nature drawings.
