Twin Cyclone Buffing

Twin cyclones are a pair of tropical cyclones, one on each side of the equator which are mainly formed from one source of disturbance. An eastward moving tropical disturbance called the Madden-Julian Oscillation coupled with Rossby waves helped fuel the twin storms by promoting convection and strong westerly winds.The twin tropical cyclones are induced by Rossby waves near the equator, according to The Hindu. These symmetric tropical storms are created by the interaction of the wind and monsoon systems, as well as the Earth system.
