In this part I’ll be discussing the interactions I had regarding the new problems on science
There is a paper on impact of Aerosols by Tegen et al (http://www.nsstc.uah.edu/~naeger/references/journals/Sundar_Journal_Papers/1998_JC_Miller.pdf) which says that the precipitation decreases in the Arabian Sea due to Aerosols, but the change in temperature is only on land as they are using an AGCM in which the SST is constant. As we have a coupled model the effects on Ocean can also be checked.
Another issue in the Nature geoscience paper by V Vinoj(http://www.nature.com/ngeo/journal/v7/n4/pdf/ngeo2107.pdf) is that he says that the dust induced atmospheric heating over North Africa and Arabian Peninsula rapidly modulates the monsoon rainfall over central India. Its not very clear as to how this takes place.
Another problem of interest that can be studied is the impact of Sea Salt over Arabian Sea on the precipitation that takes place over Western Ghats.
