Each year meteorologists around the world celebrate a chosen theme to commemorate the anniversary of the founding of the World Meteorological Organization (WMO) on the 23rd of March in 1950. “Understanding Clouds” was the theme of World Meteorological Day that year, to highlight the enormous importance of clouds for weather climate and water.

Have you ever thought that for aeroplane pilots, every day at work is a blue-sky day? Soaring above the clouds you might think that the weather isn’t such a big deal.

In this blog post, we discuss one crucial aspect of aviation weather that affects both pilots and passengers – turbulence.

Clouds come in many different types and are characterised and named according to both their shape and height in the atmosphere. While a single snapshot in time at a given location may only contain one type of cloud, there are many days when multiple cloud types can be observed in the sky at once.

It must have been an insightful man who decided to build the new meteorological office on the end of the ridge above the Botanical Gardens. If you are lucky you can observe some beautiful meteorology from the roof of the building. The Director at the time, Dr John Gabities, probably had a big say in the matter. Being a meteorologist himself, he would have appreciated the value of that siting. At lunch time on Friday (22 January 2010), I was on the roof and noticed a little drama unfolding on the harbour and took a photo with my cell phone.
