Back to days of sweat & humidity
- Experts attribute sultry conditions to easterlies, lack of natural resource hits health hub unit

The fretful 40 is back in the city as the maximum temperature on Wednesday stood at 41.4°C.

Along with the Mercury, the humid horror, too, has paid a visit with the southwest monsoon round the corner. Patna and most parts of Bihar experienced sultry weather conditions over the past couple of days. The last time the Celsius devil was seen above the 40-degree mark was on May 23 at 42.3°C. Most people have been looking up at the hazy skies with hopes of rain. The Met office has some good news for residents as they are expecting precipitation during the weekend.

“It was highly sultry today (on Wednesday). Fans were of little help and going out meant getting drenched in sweat. My daughter was getting irritated with the heat every now and then,” said Neha Singh, a Gola Road resident.

The reason behind the annoying heat is the high-level of discomfort factor — a combination of high temperature and humidity. Sources in the Met department said the discomfort factor is calculated by adding the maximum temperature and relative humidity.

On Wednesday, the highest discomfort factor was measured at 81 around 2.30pm, when the temperature reading stood around 41.4°C and relative humidity stood at around 40 per cent. Such high-level of humidity have been attributed to blow of easterly winds and the remaining moisture content of the rainfall that occurred in the last week of May. “A high pressure area seems to have developed over the Bay of Bengal owing to approaching monsoon waves. This has led to blow of easterly winds and the resultant moisture incursion in the lower as well as upper level of atmosphere,” said P.N. Chaudhary, meteorologist, India Meteorological Department, Patna. Chaudhary claimed the high temperature conditions are expected to heat up the high level of moisture enough to cause thundershowers on Saturday and Sunday.

Monsoon update

The prevailing easterly winds and high level of moisture are highly favourable for the onset of monsoon. The wind direction is also expected to remain easterly for a few weeks.

“Considering the way the easterly component of the southwest monsoon is advancing over the Bay of Bengal, it is expected to hit Bihar well on time (June 13 or two to three days earlier),” said a senior IMD, Patna official.

The midday bulletin of the IMD on Wednesday evening said conditions were favourable for advancement of the southwest monsoon over Kerala.
