Taipei, Nov. 30 (CNA) Temperatures during the upcoming winter season in Taiwan are likely to be higher on average than in recent years, the Central Weather Bureau (CWB) said Friday, while it forecast cooler weather from Dec. 7.
The cooler temperatures next week will be brought by northeastern winds, not a cold front, the CWB said, adding that winter will start somewhat later this year than usual.
Generally, the first cold air mass of the winter usually hits Taiwan between Nov. 10 and Dec. 15, but there are no indications that such a front will arrive soon, the bureau said.
Lu Kuo-chen (呂國臣), director of the bureau’s Weather Forecast Center, predicted that the first cold air mass, defined as a front that brings lows of at least 12 degrees Celsius to Taipei, will not arrive until around mid-December this year.
The first strong cold air mass, which brings lows of 10 degrees to Taipei, usually hits between Nov. 22 and Dec. 31, he said.
A cold surge, which sends the mercury in Taipei to below 10 degrees, usually arrives for the first time between Dec. 10 and Jan. 21, Lu said.
On Dec. 7, strengthening northeastern winds will bring both rain and cooler weather to Taiwan, the CWB said, but did not issue a forecast for the expected temperatures.
Over the past three months, from Sept. 1 to Nov. 28, the average temperature across Taiwan was 25.25 degrees Celsius, 0.37 degrees higher than the average for the same period last year, the bureau said, predicting that the average temperatures this winter will also be higher.
