A large contributor to climate variability in Australia is ENSO. ENSO or the El Ni o/Southern Oscillation is the term used to collectively describe the status of ocean and atmosphere circulation systems in the Pacific... Positive phases of the SOI (average monthly values of the SOI above +7.0 and often associated with a La Ni a SST pattern) reflect barometric air pressures over northern Australia being lower relative to those in the central Pacific... As autumn/early winter is the key time of the year when climate patterns such as La Ni a and El Ni o can change or develop quickly, we continue to recommend keeping an eye on the SOI and sea surface temperature (SST) trends...

The benefits improve crop health and crop competitive ability against weeds and the effectiveness of pre-emergent herbicides... When used as a post-emergent product, little of the herbicide gets to the roots and the control of established weeds is often very poor... benefits arise when the weed is prevented from setting seed as there are no increases to the seedbank and, as a consequence, fewer weeds in the future...

In a report published in Scientific Reports , a sister publication to the Nature journal, researchers have linked a decline in April-May rainfall over south-east Australia - taking in much of the grainbelt - with a polewards expansion of the planet's subtropical dry zone... Previous research into causes of the decline in autumn rainfall across regions such as southern Australia had implicated a southward shift in storm tracks (tropical cyclone belt) and weather systems during the late 20th century... "There has been a polewards expansion of the edge of the Hadley cell - also called subtropical dry zone - over the past 30 years, with the strongest expansion occurring in mid-to-late autumn, or April to May," Mr Cowan says...
