What is behind the Indian Ocean Cyclones?

Why have three cyclones developed in the Indian Ocean in quick succession?

First there was cyclone Idai, then cyclone Kenneth and now cyclone Fani. As we go to air Fani is still developing, but the earlier two were unprecedented, occurring in a manner rarely if ever seen before. What is behind these extreme events? We look at the current state of weather patterns in the region and the influence of climate change.

Astronomers join forces to search for evidence of a black hole swallowing a neutron star, and why atmospheric pollution might have reduced the severity of past droughts.
