Saharahan dust plume and how it affects tropical development

The saharahan dust  will temporarly supress any lows from forming in the  tropical atlantic ocean  because the air comeing off affica has the dust and  is soo dry it tears appart  the storms as we saw with tropical storm Dorian  last week as it tried to cross the area of dry saharahan air it had a feed from the Equatorial atlantic thats why it survived but it didnt last long after that because it intraine  dry air into the system. and dust. you would think the dust would spawn storm formation  beeing  condensation neculei  but no its the  dry air assoiated with the dust that squashes the storms and doesnt let them form.
