Abstract: | The present study brings out the influence of transport dynamics on the
aerosol distribution over the Indian region at a few selected geographically distinct
locations. Over the Bay of Bengal the dominant pathway of aerosol transport during the
pre-monsoon period is through higher altitudes (~ 3 km); directed from the Indian main
land. In contrast, the aerosol pathways over the Arabian Sea during the same period are
quite complex. They are directed from geographically different environments around the
ocean through different altitudes. However in general, the day-to-day variability of AOD at
both these regions is significantly influenced by the features of atmospheric circulation
especially, the wind convergence at higher altitudes (around 3 km). Over the Ganga Basin
during the winter period, the wind convergence at lower altitudes (< I km) govems the
shon term variations in AOD, while the mean AOD distribution at this location is mainly
governed by the local anthropogenic sources. |
