GS Paper I Geography

Context:

The weakening of Cyclone Tej in the Arabian Sea might have strengthened its counterpart Cyclone Hamoon across Peninsular India in the Bay of Bengal, as per India Meteorological Department (IMD).

Cyclone Hamoon

It is after 5 years that the marginal seas of the Indian Ocean are together witnessing cyclones.
The last time such a phenomenon took place was in 2018, when Cyclones Luban and Titli formed over the Arabian Sea and Bay of Bengal respectively.

What are the factors responsible for strengthening Cyclone Hamoon?

Shifting of Tej in the Arabian Sea: In a twin cyclonic system — Tej and Hamoon — often one gets stronger at the expense of the other. Since Tej already made landfall and is gradually weakening, Hamoon now seems to be getting stronger.
Surface temperature: The sea surface temperature of the region where it is now located is more than the earlier position, further contributing to the intensification.
