This is super-interesting to me. We are in the middle of a huge dust storm here in Puerto Rico. The dust has traveled nearly 6,000 miles across the sea from the Sahara.

Over the sea, the heavier grains eventually fell from the sky and all that is left are the finest particles. The sky is filled with a misty, almost other-wordly haze.

Small bits of Africa drift down all around us.

The locals consider these events to be good luck. It only happens when the monsoon winds in Africa are too far north. So, the low-pressure systems arrive over the sea “dry” and the dust cools the top layer of the ocean. Hurricanes cannot form in these conditions.

We are, in a way, protected by the dust. And over the eons, such events have contributed to the mineral fertility of the islands. https://news.sky.com/video/puerto-rico-hit-by-saharan-dust-which-has-moved-across-the-atlantic-12012642
