CWB warns of ‘sin­gle wolf’ Typhoon Soude­lor

The China Post - - FRONT PAGE -

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.
