Red sunset, Jugo or Canada fires? 26 June-2 July 2023

Almost 10 days since we reached Pula at the end of our odyssey. I finished the last post with the sunset below, which looks surreal. However, I did not use any "effect" to enhance the colour or saturation. The sunset was just that red!

A few nights later, after reading about it, I realised that the colour of our sunset in the Adriatic was influenced by the smoke from the forest fires in Canada, which crossed the Atlantic and southern Europe, and which we experienced in the northern Adriatic this week...While browsing around, I discovered the Copernicus website, which tracks aerosols around the world.

Copernicus indicated that the plume from Canada would pass over Pula around 30 June 2023. So we spent most of our evenings on the west-facing terrace watching the sunset over Brijuni. All better than each other!

On 27 June, we spent dinner and the evening in Fažana with our departing crew. The sunset was magnificent again!

Then the weather changed and we experienced a few days of jugo, the local sirocco that blows from the Sahara to the north, causing unstable weather in the Adriatic along the Croatian coast, with alternating sun, clouds and rain. Jugo also causes red sunsets due to the amount of dust from the Sahara that it carries across the Mediterranean and drops over Croatia, laden with humidity acquired during the sea crossing.

So, all these pictures to insist that the pictures are not manipulated, but reflect the reddish colour expected in these waters under Sirocco or any other international situation that would spread aerosols over the Croatian coast, such as the ash carried across the Atlantic by the Canadian fires. 

This phenomenon has been studied and published in an article written by a Greek team that examined hundreds of paintings from between 1500 and 2000. The study looked at the overall proportion of red and green in the painting and concluded that there was a significant correlation between the amount of red in the paintings and the 5O major volcanic eruptions that took place during this period. One example is Turner's 1839 painting of the Fighting Temeraire, a ship in Nelson's fleet at the Battle of Trafalgar in 1805, which contributed to the British victory by saving Nelson's admiral ship during the battle.

Tonight the Jugo was gone, but we could still see the reddish effect of the sunset around the clouds on the horizon. I have a feeling we are going to be addicted to our terrace for the next few weeks!
