  • A study titled “Changing status of tropical cyclones over the north Indian Ocean” was conducted recently.
  • This study revealed how climate change is making cyclones more intense on both sides of the Indian coast.
  • The translation speed of cyclones (the speed at which cyclones move) has decreased in the Arabian Sea.
  • During 1982–2019, a significant increasing trend in the intensity, frequency, and duration of cyclonic storms (CS) and very severe CS (VSCS) was observed over the Arabian Sea.
  • There has been a 52% increase in the frequency of CS during the recent epoch (2001–2019) in the Arabian Sea.
  • There is a decrease of 8 percent in the Bay of Bengal.
  • Temperatures have been between 30-32 degrees Celsius in the Bay of Bengal.
  • These high temperatures play a very important role in the intensification of cyclonic storms as they infuse more convection.
