Nagpur: Wondering why this December is rainier, foggy, and wetter than the norm for Nagpur? “Climate variability” is the answer, say weather experts.
Christmas came as a surprise to citizens, with many parts of the city receiving low rainfall. Nagpur Regional Meteorological Center (RMC) officials said it started raining late Wednesday night, with drizzle continuing through early Thursday morning in some areas.
The city recorded 9.6 millimeters of rain until 8:30 a.m. Thursday, officials said. Also earlier this month, the city had received light showers.
The discontinuity in the flow of winds brings humidity and rains to the area, said Mohanlal Sahu, deputy general manager of RMC, Nagpur. “Winters have a well-defined pattern: northerly winds hit central India and mercury levels drop. Currently, the wind that arrives in our region is not completely from the north, ”he said.
This is due to the continuous high pressure circulation over Telangana and Andhra Pradesh. “The current configuration is such that westerly and southwest winds are blowing in the region. And because of the high pressure circulation, these winds bring humidity. As a result, the mornings are cloudy and many areas of Vidarbha receive light rain, ”Sahu said.
Compared to recent years, this month of December seems to be much warmer. Explaining the unusually high temperatures, Sahu said, “When the atmosphere is cloudy, the minimum temperature does not drop. For it to fall, the sky must be clear.
Another unusual weather condition that many citizens talk about is a layer of haze enveloping the city. According to Sahu, this condition can also be attributed to the presence of moisture in the air. “When temperatures drop early in the morning, the presence of water particles in the air causes a foggy state. With a further drop in temperature, the haze will turn to fog, ”he said.
Noting that not all unusual weather conditions can be attributed to climate change, Sahu said, “Climate change is a slow and continuous process. Although the winter of this year does not seem as cold as last year – when December recorded a minimum temperature of three degrees Celsius – we cannot call it “climate change”, because the winter of the next year could be cooler. What is happening now is climate variability.
Current weather conditions should change in a day or two. “After January 1, we expect the northerly winds to pick up. Minimum temperatures will drop, ”Sahu said.
