<p>What's the difference between sandstorms and regular storms? Are they more than just strong wind within deserts?</p>

It is also important to think about wind speed and how this influences which grain sizes (sand is a grain size in geology) can be picked up: Bagnold, R.A. 1937. The transport of sand by wind. The Geographical Journal 89(5):409-438. https://en.wikipedia.org/wiki/Ralph_Alger_Bagnold
