Third warmest November in India since 1901

PUNE: Last month was the third warmest November in India since 1901, with warmer nights than usual due to recurring periods of rain and cloudiness. The average temperature in India in November was higher than normal (climatic average) at 0.72 degrees. November 2015 was the warmest in 118 years, with an increase of 0.87 degrees.

India witnessed its second warmest November in 1979, when average temperatures were 0.86 degrees higher than normal. When only the average minimum temperature is considered, November this year was the second warmest since 1901, said Arvind Kumar Srivastava, head of the IMD Pune Climate Research Division.

The average minimum temperature last month was higher than normal at 1.5 degrees, while November 1979 witnessed an increase of 1.64 degrees. In Delhi, the average minimum temperature during the month was 2.1 degrees C above the weather average. Alka Gadgil, climatologist and professor emeritus, said that the frequency and influence of low pressure systems and cyclones on both and Bengal Bay was high in November, causing a significant nighttime cloudiness in some parts of the country.

Srivastava said that cyclones Maha and Bulbul caused a significant incursion of moisture in various parts of southern and central India. The ensuing cloudiness prevented a fall in minimum temperatures. “Cyclone Maha caused heavy rains and raids of moisture in and to the south. In addition to causing premature heavy rains, the large amount of moisture delayed the progress of winter temperatures in Maharashtra and the surrounding regions, ”he said.

The presence of moisture near the surface at night catches the heat, preventing its escape into the atmosphere.

Another IMD official said the maximum temperatures in November were lower or almost normal in India, but the minimum temperature was high in many parts of the country. “In central and southern India, we had a lot of moisture incursion, which caused cloudiness at night, which led to higher lows.

In southern India, the maximum and minimum temperatures were higher than normal. In northern India, there were not many western disturbances, which brings cold weather once they pass, the official said, adding: The influence of any western disturbance felt in northern India was mainly limited to parts of the north. Extreme like Kashmir.

In Delhi, for example, the lowest minimum in November was 11.4 ° C, when it generally falls below 10 ° C.

Also in Pune, the lowest minimum was 14.1 ° C (in Shivajinagar), recorded on November 26. In the last decade, the lowest lows in November of Pune have generally been in the range of 7-12 ° C, due to the north winds entering Maharashtra in mid-November. However, IMD said that the cold winds from the north could not enter the state this winter due to the presence of an anticyclone over central India, preventing temperatures from dropping.
