Why Is India's Heat Wave Off the Chart?


It got so hot in the city of 45,000 inhabitants that those brave-or
perhaps unwise-people who dared to venture outdoors despite an official curfew found it difficult to remain there long. One man, a government employee named Murari Lal Thanvi, told BBC News that the
heat was so punishing that his mobile phone, which he was trying to use to take pictures, stopped functioning because of overheating. "I was able to switch my mobile phone on after putting a wet
cloth on it for about 20-25 minutes," he explained. The unprecedented high was part of a heat wave that's been punishing northern India, according to the Indian Meteorological Department, a division
of the national governments's Ministry of Earth Sciences. The department issued a warning of brutally more hot temperatures over the next five days. While there's typically a stretch of several weeks
in the spring when temperatures exceed 100 degrees in the run-up to the monsoon season, this year is much more brutal. NEWS: Earth's 2015 Temperatures Warmest on Record It got so hot it even hindered
the city's extensive solar power-generating system. The latter, which has a capacity of 700 megawatts, reportedly generated 3 to 5 percent less electricity than usual. That's because solar power is
produced by the contrast between low-energy electrons in solar panels and the sun's higher energy. When panels get too hot, it lessens the contrast, according to an FAQ by scientists at the
University of California-Santa Barbara.
