Today in Spain we are receiving muddy rain, which happens when there is a wind from the south that picks up sand from the Sahara. It reminded me of a science fiction novel I read about 10 years ago, but which was much older, probably dating from the 1970s. It dealt with a situation where the wind started to blow continuously, and to increase its velocity every day. I do not believe that a specific physical cause was given. Because of the increasing wind speed, the landscape began to be eroded as the wind carried away the soil, and bodies of water started to dry up.

I do remember that one of the main characters was a scientist, and he used a rain gauge to measure the amount of soil which fell from the sky each day. He must have been based in London as there was a description of the population huddling in the Tube when it became unsafe to stay on the surface. I am not sure exactly how it ended, but I believe that an insane millionaire (or maybe billionaire) constructed a steel pyramid to live in to defy the wind. The pyramid was indeed impregnable, but it toppled over as the wind removed the ground it stood on.

I thought it might be the sort of global catastrophe that John Wyndham or John Christopher might have written, but I do not see anything in their works which matches.
