The relationship between aerosol concentrations and tropical cyclone (TC) formation is investigated. Sixty-three convective cloud clusters in the tropical Atlantic that developed into TCs (developers) and 98 tropical Atlantic clusters that dissipated before becoming a TC (nondevelopers) were examined. Aerosol content (as measured by satellite-derived aerosol optical depth) near developers was averaged; likewise for nondevelopers. The average aerosol content surrounding developers was much higher than that surrounding nondevelopers. This indicates high aerosol concentrations do not significantly inhibit a cluster’s ability to develop into a TC, which is contrary to widespread perception. Several analyses indicate the measured difference between developer and nondeveloper aerosol content is quite robust.
