July's rainfall beats records from 30 years ago -- blame it on global warming?
July isn't over yet but Hong Kong has seen record rainfall. The Hong Kong Observatory recorded more than 500mm of rain in the first three weeks of this month, more than the average 376mm for the past 30 years.
The rainfall for July also exceeds the averages for June at 476mm and 432mm for August.
Johnny Chan Chung-leung, chair professor of atmospheric science at City University says global warming will result in more water vapour in the atmosphere, and so the frequency of heavy rain will only get higher.
Last Monday evening when I was caught in the red rainstorm warning, the observatory recorded 184.6mm of rain, the third-highest amount recorded in one day in July over the past 20 years.
We might have a respite from the rain this week -- overall sunny with a few showers for the next few days.
All I can say is -- thank goodness I finally invested in rubber boots!
