New system develops in Bay of Bengal; heavy showers likely in Telangana
Hyderabad: Another upper air circulation has formed above west central Bay of Bengal but has not been established yet. If this circulation persists and turns into a low pressure area, Telangana will be under heavy rainfall warning up to October 2.
The IMD software shows strong indications of the upper air circulation moving towards TS and coastal AP. IMD-Hyderabad director Y.K. Reddy said: “The IMD global forecast models are indicating another upper air cyclonic circulation forming above west central Bay of Bengal , but it is not established yet. The IMD will get clarity by September 25 on whether or not it will intensify. Heavy rainfall has been announced up to September 29. If the fresh system intensifies, TS and AP will receive another spell of heavy rain.”
If the upper air circulation intensifies into a low pressure area and moves inland, it would facilitate high intensity cloud formation leading to heavy rains.
Apart from this, there is a well-marked low pressure area over TS and south Chattisgarh and Vidarbha. On Saturday. Armur of Nizamabad received 39 cm of rain followed by Madnur, Ranjal (Nizamabad) and Nirmal of Adilabad with 20 cm rainfall.
Winter could be severe too
The above normal rainfall in the current is an indication that winter temperatures will be lower than normal this year, officials said. Winter temperatures are calculated based on five factors, of which, monsoon is one. Since a majority of states received above normal rainfall during the southwest monsoon, there was a probability that the winter would be severe.
AP and Tamil Naidu will receive rain in mid-October and November as part of the northeast monsoon, which could affect the winter temperatures
IMS-Hyderabad scientist A. Dharmaraju said, “There is increasing evidence that the atmosphere influences the land surface processes, which in turn affects the atmosphere. It is a general phenomenon that if the rainfall is intense, that year the winter will be severe too.”
