Thick cloud replaces sunny skies

Staff Reporter

Bangalore: The blue skies, chilly nights and blazing afternoons that the city has seen in the last week seemed almost akin to a hill station experience. But as if with the snap of a finger it was all over and on Monday, the sunny skies were replaced again by a thick cloud cover and a light drizzle of 0.1mm — the kind of November weather that Bangalore is more accustomed to.

These dramatic weather changes in the city in just a short span of time are directly linked to the cyclone Sidr that formed over the Bay of Bengal, explains G. S. Vijayaraghavan, Director, Meteorological Centre. The raging cyclone, which was responsible for depleting moisture from over the peninsula and for the sudden mercury dip to a record 12.7 degrees Celsius last Thursday, made way for the northeast monsoon on Sunday, he said.

The northeast monsoon which had set in the second week of October, had been stopped in its tracks by the cyclone for almost a week, he added.

“Until Sunday, Bangalore experienced dry, cold weather, brought in by northerly winds — a direct result of the cyclone.

Now that the cyclone has crossed over the Bay, an easterly wave now dominates over the peninsula.”

The easterly winds from the Bay of Bengal are associated with cloudy weather and rain, Mr. Vijayaraghavan said.

Also, with this change in wind system, the huge gap between the early morning and afternoon temperatures (with a nearly 17-degree difference on Thursday) that Bangalore had seen over the last week, is now closing, he added.


On Monday, the difference was less than 5 degrees, with a maximum of 24.3 degrees and minimum of 19.5 degrees.

The northeast monsoon over Tamil Nadu is bound to influence the adjoining districts of south interior Karnataka, he said. Bangalore, Kolar, Tumkur, Mandya and Chamrajnagar can expect moderate rain in the next 48 hours, said Mr. Vijayaraghavan.
