China builds record-breaking 100-metre observation tower in South China Sea

China has built the tallest environmental observation tower in the South China Sea, the country’s meteorological administration has said. Standing at 100 metres (330 feet) tall, the tower is almost three times higher than the previous tallest structure in the South China Sea and built to withstand super typhoons with wind speeds of over 200km/h (125mph), heavy waves, high humidity and high levels of salinity. It is equipped with sensors to collect round-the-clock, real-time data on wind speeds,.
