I read that it was increased wind shear and mid level dry air. Sahara-something. Dust too, but not sure what the dust does. Mainly the dry air--possibly from subsidence too? I'll google it! Despite the strength of a full blown hurricane, they're easy to disrupt. Another ingredient is Sahara dust storms. Dry desert air blowing westward can overrun and weaken Atlantic storm systems. Dust, on the other hand, can serve as nucleation points for water vapor, causing rain. This interplay between ocean and desert is not fully understood. science.nasa.gov Ah, here it is SAL, Sahara air layer publicaffairs.noaa.gov
