City residents feel the chill as temperature drops

Unusually, residents across the city felt a definite chill throughout the day.

On Sunday, the maximum temperature at Nungambakkam was 24 degrees Celsius, which is a departure of – 5.5 degree Celsius from the normal temperature of 29.5 degree Celsius this time of the year. Similarly, Meenambakkam recorded a maximum temperature of 25.1 degrees Celsius, which is a departure of –4.6 degree Celsius.

In the 24 hours ending 8.30 a.m. on Sunday, Nungambakkam recorded a minimum of 20.7 degree Celsius and Meenambakkam 21.3 degree Celsius. At 5.30 p.m., Nungambakkam recorded 22.6 degrees Celsius and at 8.40 p.m. 22.9 degree Celsius.

Senior meteorologist Y.E.A. Raj said that since there was little sunshine on Sunday, there was reduced incoming radiation. This, coupled with cold surface-level winds from the north could have led to the drop in temperature.

Chennai being a coastal city does not have high deviations in minimum temperature, unlike in interior stations like Vellore or Salem or Tirupattur since the sea surface temperature of the Bay of Bengal off Chennai remains at 27 degrees Celsius - 28 degree Celsius, he added.

In the 24 hours ending 8.30 a.m. on Sunday, Madurai City recorded the lowest minimum temperature of 17.8 degrees Celsius in the plains and Kodaikanal recorded the lowest minimum temperature of 10.9 degree Celsius in the hill areas of the State.
