Wall Of Dust In Australia

There is an interesting wall of dust that have been sighted in Australia.

Daily Mail reports:

"An enormous wall of dust has hit part of Australia as residents brace themselves for a tropical cyclone.

The stunning images of the wild dust storm were captured by tugboat works and aeroplane passengers near the town of Onslow in north-western Australia.

Local reports say the huge swathes of red sand and dust had been picked up by strong winds in the Indian Ocean before being dropped near the town."

Higher temperature from climate change results in faster evaporation of water from the soil. Therefore, if rainfall is unchanged in a region, then it takes fewer days after a rain storm for the soil to dry out, meaning that there are less days of moist soil and more days of dry soil over the course of a year. More days of dry soil increase the chance of a dust storm. As what is now somewhat plant covered semi-arid desert region experiences more dry days, the vegetation will die out over the course of years, creating an even greater chance of a dust storm.

Thank you so much for the comments. They are very insightful and informative. :)
