  "account": "In the humid tropics of Southeast Asia, Bangkok, Thailand's bustling capital, is prone to afternoon thunderstorms that bring torrential rain. Despite the city's drainage systems being designed to handle short, heavy downpours, a recent spell of heavy rainfall overwhelmed them. In just 48 hours, roughly 300 mm (11.8 inches) of rain fell, prompting authorities to declare a citywide disaster zone. At least 31 people died and thousands were forced to evacuate due to the sudden and extreme flooding. This downpour was caused by a low-pressure system that remained over Bangkok for three days, causing the moisture in the air to condense and form clouds and rain. The Gulf of Thailand's unusually warm sea surface temperatures provided ample moisture and energy for the storm to persist. Thailand has faced severe flooding before, with the 2011 event causing over 800 deaths and US$46.5 billion in damage. The city of Bangkok sits on a floodplain near the mouth of the Chao Phraya River and has been sinking for decades due to extensive groundwater extraction. Urbanization has also increased surface water runoff by 25% during extreme rainfall events. While it's too early to determine the exact impact of climate change on this specific rainfall event, global extreme rainfall trends suggest that extremely rainy days are getting wetter. Warmer temperatures allow the atmosphere to hold more water, which could lead to more intense rainfall in the future. Although it's uncertain if climate change will affect stalling low-pressure systems, when they do form, we can expect more intense rain. Bangkok's urban drainage systems need to be designed to handle both present-day extreme rainfall and projected intensifying rain. Investing in green infrastructure, permeable pavements, and improving early warning systems can help reduce the impacts of these extreme floods.",
  "summary": "In the humid tropics of Southeast Asia, afternoon thunderstorms roll through almost every day. Daytime heat causes towering, fluffy cumulonimbus clouds to form and swell before unleashing torrential rain on cities such as Singapore, Hong Kong and Bangkok. In these places, drainage systems are designed to cope with short, heavy downpours.",
