Four to seven typhoons expected to hit Hong Kong in 2015

Hong Kong is expected to be hit by four to seven typhoons in 2015, although there might not be any such weather disturbance before June, the city’s observatory said.

The annual rainfall this year is forecast to be normal or below-normal at around 2,000 to 2,600 millimeters.

Shun Chi-ming, director of the Observatory, urged the public to remain vigilant against possible storm surges as the local sea level continues to rise.

He also said the temperature will remain high, with heat waves and hot spells likely to become more frequent due to global warming and the El Niño effect, Apple Daily reported.

The average temperature was 27.6 degree Celsius from June to November last year, a record since 1884.

Meanwhile, the Observatory has reviewed and updated the impact on Hong Kong of sea level rise and extreme temperatures in the 21st century based on the Fifth Assessment Report of the United Nations Intergovernmental Panel on Climate Change.

Under the high greenhouse gas emission scenario, the sea level is expected to rise by 0.63 to 1.07 meters by the end of this century (2081-2100) when compared with the average sea level in 1986-2005.

With the elevated sea level, the risk of typhoon-generated storm surges affecting Hong Kong will be enhanced.

The number of hot nights and very hot days will increase dramatically in the 21st century while the number of cold days, when the temperature drops below 12 degrees, will decrease significantly to one day in winter each year.

“Climate change is here and now. Positive actions should be taken without any further delay,” Shun said.
