In the 19th century, the “rain follows the plough” myth was based on the theory that cultivation increased rainfall by moistening the soil and humidifying the atmosphere. Subsequent research has debunked the myth, finding there are three ingredients necessary to create rain: moisture, an upward motion of air and a source of water vapour.
Handy rains across Australia’s western and southern regions through the week have bolstered winter crop prospects, particularly in Western Australia and the southern parts of South Australia and Victoria.
The latest NSW Department of Primary Industries (DPI) State Seasonal Update for June indicates some welcome rain was received in southern NSW, but the majority of the state continues to endure dry conditions.
Widespread rain across much of the Western Australian cropping belt over the past couple of days has boosted winter crop prospects, particularly in the northern and central regions.
A rain front that passed over the parched eastern Australia cropping belt in the past few days brought solid falls to parts of Queensland and the western farming regions of New South Wales, but largely missed the desperately dry northern NSW slopes and Hunter Valley.
Northern Australia and the south east mainland are likely to be drier than average for the July to September period, according to the latest outlook from the Bureau of Meteorology.
Rain across the southern farming regions of Victoria and South Australia this week has come at a crucial time for winter cropping programs.
A high degree of ‘scatter’ in weather forecasting models is making it hard to predict what’s in store for the forthcoming winter cropping season, according to CottonInfo/AgEcon climate risk technical lead, Jon Welsh.
Climate models suggest the El Niño–Southern Oscillation (ENSO) will remain neutral through winter and temperatures will remain close to average through the southern hemisphere winter.
Weather extremes are impacting on grain crops in the United States where drought has prevailed throughout the wheat-growing season in many areas, while flooding has hit some eastern grain-growing regions.
