New Delhi: When humans feel hot, they cool themselves with sweating.
However, if the moisture is too high, sweating no longer works and one risk is too hot.
In this case, the “wet” temperature is used to measure heat and moisture, helping to estimate whether the condition is safe for humans or not.
It is measured on a different scale compared to normal temperatures, where 35 degrees Celsius is the maximum limit or threshold, 32 degree wet bulb temperature can mean that even suitable, the acclimatized person will not be able to work easily.
At temperature wet bulbs 35 degrees Celsius, it is even suitable, people who are acclimatized can suffer heatstrok and have the potential to die if they are outdoors for a long period of life, research shows.
With climate change, the number of potentially dangerous days, where high heat and moisture combine, also increases.
At present, Delhi records 63 days like that every year, but this can increase to 131 days in 2100 under the scenario of “business as usual”, estimates show.
At present, most Indian experiences are 12 to 66 days each year from hot potentially this deadly and this high moisture combination with hotspots along the east coast, such as 124 days in Kolkata, 171 days in Sundarbans, 178 days in Cuttack, 173 days at Cuttack Brahmapur, 113 days in Thiruvananthapuram and 140 days in Chennai, according to Research 2017.
Mumbai, meanwhile, recorded 47 days like that.
Under the scenario of “business as usual” or RCP 8.5, where emissions are expected to increase at the same level, wet days are expected to touch 99 every year in Delhi in 2050 and 131 at 2100.
Even under strict emissions scenarios RCP 2.6, where global temperatures increased less than 2 degrees Celsius at 2100, Delhi will still see 81 days like that every year.
Rachel White, an atmospheric scientist with the University of British Columbia, said that adding a humid heatwave is far more dangerous than dry heatwa.
“With the temperature of wet bulb, someone can increase it with one of two ways.
Somehow you increase temperature or moisture, and it is clear worse if both are increasing,” he added.
Being outdoors during high wet bulb temperatures can cause heatstroke and lighteradedness, nausea, organs swelling and, in rare cases, death.
While human skin has a temperature of around 35 degrees Celsius, a wet ball with the same heat means sweat can no longer be used to cool the body.
In some cases, the temperature of wet bulbs as low as 28 degrees Celsius also leads to mass mortality throughout the world.
Real-time data on Tuesday shows the part of Uttar Pradesh touched a wet bulb of 31 degrees Celsius, while Delhi was at 25 degrees.
In East India, it ranges from 26 to 29 degrees.
“Your ability to cool the sweat is not limited.
At some point, the body starts to heat up like other objects and you through various problems.
You become dehydrated.
Your skin dries and various organs begin to be closed, including your kidney, heart and brain,” said Georges Benjamin, “said Georges Benjamin,” said Georges Benjamin, Executive Director of the American Community Health Association.
The wet-bulb temperature is measured by wrapping a wet cloth around the thermometer bulb.
This represents the lowest temperature air that can reach with water evaporation.
Internationally, the wet-bulb ball temperature is calculated using the Globe thermometer and also accounting for solar radiation and wind speed.
