The weather forecast for October 27-29 indicates dominant northeast winds over northern Maldives, with southeast winds prevailing at the equatorial region. At the surface, northeast winds are observed, while southeast winds are noted at 3.5 km above sea level. The South Indian plume is a significant source of pollutants, particularly black carbon (BC) comparable to sulfate levels on the 27th. However, sulfate levels decrease on the 28th, with notably strong organic carbon (OC) contributions over Hanimaadhoo Climate Observatory. The marine layer shows very clean ozone levels in the surrounding area.
