Re­gion put on watch for La Nina

North West Telegraph - - Telegraph News - Tom Zaun­mayr

North­ern Aus­tralia seems likely to ex­pe­ri­ence an­other bumper wet sea­son, with con­di­tions shap­ing up for heavy rain­fall over the com­ing months.

The Bu­reau of Me­te­o­rol­ogy has put the coun­try on a La Nina watch no­tice, which typ­i­cally means in­creased mon­soonal ac­tiv­ity in the north over sum­mer.

CQ Univer­sity en­vi­ron­ment ge­og­ra­phy ad­junct pro­fes­sor Steve Tur­ton said at­mo­spheric in­di­ca­tors were point­ing to­wards a short-lived La Nina event.

“While the El Nino — south­ern os­cil­la­tion re­mains neu­tral, mod­els are sug­gest­ing that the trop­i­cal east­ern Pa­cific Ocean will con­tinue to cool,” he said.

“It’s un­usual for a La Nina to oc­cur so late in the year, which means that if it does oc­cur, his­tory sug­gests it will prob­a­bly be short-lived.

“We could po­ten­tially be in for above-av­er­age rain­fall in north­ern Aus­tralia for the next three months.

“How­ever, the com­pet­ing in­flu­ence of warm wa­ters to the north of Aus­tralia and cool wa­ters in the east­ern In­dian Ocean do not favour wide­spread rain­fall for November to Jan­uary.”
