A study published in the journal Science states that the incidence of drought or drought in India is historically associated with El-Nino. It also states that Rossby currents may be responsible for about 6 out of 10 drought or drought events occurring in non-El Nino years during the summer-monsoon period in India. It is also reported that Rossby currents. They are generated by atmospheric disturbances in the Atlantic region. Rossby waves occur naturally in rotating fluids. Within the Earth's ocean and atmosphere, these waves play an important role in shaping the weather. Rossby waves, in meteorology, are large horizontal atmospheric oscillations that are associated with polar-front jet streams and separate cold polar air from warm tropical air.
