The dense pitch-black clouds over Chachoengsao in Thailand are a sign of extreme weather
The pitch-black clouds blocking the sun on the east side of Greater Bangkok yesterday were cumulonimbus clouds or dense vertical clouds formed by condensation in the lower troposphere.
In a Facebook post, the Thai Meteorological Institute said: “When cumulonimbus clouds move quickly, they can develop arcus clouds or a low, horizontal cloud formation that expands from rain clouds and can be seen from several kilometers away.
“The rain clouds formed over Chachoengsao Monday morning and moved east to cover the Greater Bangkok area. Its thickness blocked out most of the sun’s light. The clouds were so thick and dark that the sky looked like it was nighttime,” the message read.
Thai biologist Thon Thamrongnawasawat has linked this cloud phenomenon to global warming.
“As the oceans get warmer, more vapor is released into the air, forming thick clouds that hold an enormous amount of water,” he wrote in a Facebook post. “These clouds are thicker than usual and can cause heavy downpours. Fortunately, the strong wind blew most of them away and we got light rain on Monday.
“This is just the beginning of the era of ‘extreme weather, caused by decades of greenhouse gas emissions,” he said. “This year we have already seen it happen in Pakistan, where heavy rains over eight weeks have caused major flooding that has killed more than 1,000 people and displaced more than 33 million people.”
Thon, who is an assistant dean at Kasetsart University’s Faculty of Fisheries, called on people to do their part to reduce global warming.
“The storm is getting closer and closer. We all know what to do, so we should do it as much as possible. Compared to what’s to come, this minor inconvenience is nothing we can’t handle,” he said.
