Sta­tis­tics re­veal dry 2018

Central and North Burnett Times - - NEWS -

THE Bu­reau of Me­te­o­rol­ogy has re­vealed that 2018 was one of Aus­tralia’s dri­est years.

Across the coun­try rain­fall was 11 per cent below the na­tional av­er­age for the year at 412.8 mil­lime­tres.

This is 52.4mm less than the na­tion’s av­er­age for 1961–1990 mak­ing it Aus­tralia’s 39th-dri­est year in a record span­ning 1900 to the present.

The rain­fall was below av­er­age for very large ar­eas, af­fect­ing cen­tral and south­ern Queens­land, New South Wales, Vic­to­ria, east­ern South Aus­tralia, and Western Aus­tralia

While low rain­fall has per­sisted over many ar­eas of the south­east for more than 12 months, the pos­i­tive In­dian Ocean Dipole in spring sig­nif­i­cantly ex­ac­er­bated drought con­di­tions across the coun­try.

BOM re­ported that the dry con­di­tions were also some­what con­sis­tent with long-term rain­fall trends.

Low rain­fall, low hu­mid­ity, high wind speeds, and high day­time tem­per­a­tures re­sulted in high evap­o­ra­tion, below-av­er­age soil mois­ture, and low stream­flows dur­ing win­ter.
