Expert says that while southern China is more prone to heavy rainfall due to monsoon, exact pattern is highly unpredictable

Hong Kong’s Tseung Kwan O has experienced the highest cumulative rainfall in China so far this year, with 2,397mm (94.37 inches) recorded in the first 7½ months, topping a chart from the national meteorological centre.

But Leung Wing-mo, former assistant director of the Hong Kong Observatory, said on Thursday that while southern China was more prone to heavy rainfall under the influence of a southwestern monsoon, the exact pattern was highly arbitrary.

“There is no special reason. Heavy rainfall is purely random. This time it is Tseung Kwan O; next time, it will be elsewhere,” he said.
