North Indian Ocean Cyclone in 2023 From Wikipedia, the free encyclopedia
Severe Cyclonic Storm Michaung[a] (Burmese pronunciation: [mɪʔtɕʰaʊɰ̃]) was a moderate tropical cyclone which formed in the Bay of Bengal during the 2023 North Indian Ocean cyclone season. Michaung originated as a low-pressure area in the Gulf of Thailand which crossed into the Bay of Bengal and became a deep depression on December 2. It developed into a cyclonic storm thereafter and was named Michaung. It was the ninth depression and the sixth named cyclonic storm of the season. The cyclone gradually moved north-west over the next few days towards the eastern coast of India. The storm peaked with sustained winds of 60 knots (110 km/h; 70 mph) causing heavy rainfall in north-eastern Tamil Nadu including Chennai and south-eastern Andhra Pradesh before making landfall near Bapatla in Andhra Pradesh on December 5.

Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionIn late November 2023, a low-pressure area crossed into the Bay of Bengal from the Gulf of Thailand. On December 1, the India Meteorological Department (IMD) said the disturbance had developed into a depression in the South Andaman Sea, and was expected to move towards the northwest while strengthening in the Bay of Bengal.[3] On December 2, the system intensified into a deep depression located about 440 kilometres (270 mi) east-southeast of Puducherry.[4] Thereafter, it intensified into a cyclonic storm, and was assigned the name Michaung by Myanmar.[5]
On December 4, cyclone Michaung reached peak intensity as it approached the coast of Tamil Nadu with winds of 110 kilometres per hour (68 mph), equivalent to a high-end tropical storm on the Saffir–Simpson scale.[6] Michaung moved almost directly northward along the coast. On December 5, the storm made landfall between Nellore and Machilipatnam in Andhra Pradesh, weakening as it moved inland.[7] By December 6, the storm had weakened to a depression over central Andhra Pradesh.[8]
According to the IMD reports, INSAT-3D satellite imagery on December 5 indicated a cloud mass with broken low to medium clouds and intense convection extending over west-central Bay of Bengal and the coastal region of Andhra Pradesh, spanning from latitude 13.5°N to 17.5°N and longitude 80.0E to 82.5E. The minimum cloud top temperature was recorded at −90 °C (−130 °F). Coastal surface observations from various locations on the coast indicated a maximum wind speed of 60 knots (110 km/h; 69 mph) and a minimum sea level pressure of 988 hectopascals (29.2 inHg).[9][10] Nungambakkam in Chennai recorded the maximum rainfall of 530 mm (21 in) in the three-day period between December 2 and 4.[11]
