Question 5GS1GS1
Discuss the factors responsible for increased cyclonic activity in the Arabian Sea. (Answer in 150 words)
Main Body
According to IMD report 2024, there is sly increase in frequency and intensity of cyclonic activity in Arabian sea compared to Bay of Bengal in last 8 years.
Factors responsible for increased cyclonic activity
1LOMO predicted during global warming in Indian ocean and specifically in Arabian sea → absorbed low temperature and high evaporation suction.
2Rising sea surface temperature in Arabian sea → create more severe cyclonic activity (ex) Biparjoy cyclone
3Rising El-Nino phenomena and negative Indian ocean Dipole accelerated warming in Arabian sea
4Favorable winds coming from Bay of Bengal → shifted maybe of cyclones from Baay of Bengal to Arabian sea. (ex) Taukley cyclone shifted case 2023
5Otey climatic conditions (rate of Madden Julluy escalations → renewable damping effect)
Rising climate change in Arabian ocean
Weakening of AMOC
These became complex case study as evident in higher rainfall over western coast. It require comprehensive study to analyze changing pattern of cyclonic activity. (ex. Priscio Mausum)
