CWB warns of ‘single wolf’ Typhoon Soudelor
The Central Weather Bureau (CWB) warned Tuesday of the potential damage Super Typhoon Soudelor may cause Taiwan, describing it as a “single wolf” typhoon.
Though the storm’s center is still 2,000 kilometers away, it is moving at a speed of 21 kilometers per hour toward northern Taiwan, and the CWB urged the public to be on the alert as the typhoon approaches.
The bureau said it could issue sea and land warnings for the typhoon on Thursday.
Describing Soudelor as a “single wolf,” the bureau said it would bring heavy winds and rain to Taiwan but would sweep across the island quickly rather than hovering period of time.
It is expected to affect Taiwan the most from late Friday night to Saturday morning but then move away without drawing in weather fronts from the southwest as many typhoons do, the CWB said.
The bureau could not confirm if the center of the typhoon will make landfall in northeastern Taiwan as its present course might suggest, saying it was too early to determine what path the storm will follow in the coming days.
Wu Der-rong, a professor in National Central University’s Department of Atmospheric Sciences, said that because the winds in the center of the typhoon are especially powerful, where the
for an extended typhoon lands will be very important, and he reminded people to follow it closely.
Wu expected Soudelor to gain strength as it approaches Taiwan because of its weak vertical wind shear — a measure of the difference in wind speeds at different heights of the storm.
The greater the wind shear of a typhoon, the more it removes the heat and moisture the typhoon draws on for its strength, and it can also distort the axis of a storm, making it less efficient.
