Remote Impact of Black Carbon Aerosols Through Rossby Wave Phase Shift Arindam Chakraborty, R S Nanjundiah and J Srinivasan It was shown by several previous studies that black carbon aerosols could impact convection, especially over Asian region, locally. However, the exact impact of black carbon aerosols on monsoon remains inconclusive. The present study uses an atmospheric general circulation model to that remote influence of aerosol-like heating can be as strong as local influence on Indian summer monsoon. Precipitation in northern Arabian Sea increased by 28% when aerosols were present only over south Asia, and was increased by 13% when aerosols were present only over east Asia. The remote heating of aerosols modulated the phase of the upper tropospheric Rossby waves to favour upper level divergence and subsequent convection over South Asia. Our results show that atmospheric heating of one region can influence convection of remote location through atmospheric teleconnection.
