Go to Chart Discussion: Fri-17-Aug-2018 (Harvey Stern) Current BoM Seasonal Outlook Issued 16-Aug http://www.bom.gov.au/climate/ahead/archive/outlooks/ The climate outlook, issued 16 August 2018, shows the first months of spring (September and October) are likely to be drier than average for most of northern, eastern and southern Australia. Spring days are likely to be warmer than average. Nights are also likely to be warmer than average for most areas, except for parts of northern Australia and the southeast of the mainland. 9
Seasonal Outlook (Statistical Model) Victoria Sep. Oct. Nov. The average Indian Ocean Dipole Mode Index for the past week is 0.16 (0.31 standard deviations), the average Southern Oscillation Index (SOI) for the past 90 days is -1.49, the average SOI for the past 30 days is 0, and the latest recorded bimonthly Multivariate ENSO Index (MEI) is 0.469. The expected MEI, adjusted by the Indian Ocean Dipole Mode Index and also by recent values of the SOI, for JUL/AUG is 0.29. Such a value of MEI indicates a sea surface temperature distribution that corresponds to a very weak El Niño. This suggests: RAINFALL: There is a very slightly enhanced chance that total SEP/OCT/NOV rainfall will be below normal in all Victorian Districts. OVERNIGHT TEMPERATURES: There is a very slightly enhanced chance that average SEP/OCT/NOV overnight temperatures will be below normal in the NORTHERN COUNTRY, NORTH CENTRAL, NORTHEAST, EAST GIPPSLAND, WEST GIPPSLAND and WESTERN Districts, there is a very slightly enhanced chance that overnight temperatures will be above normal in the MALLEE District, but there is little indication as to whether overnight temperatures will be below, near or above normal in other Victorian Districts. DAYTIME TEMPERATURES: There is a very slightly enhanced chance that average SEP/OCT/NOV daytime temperatures will be above normal in all Victorian Districts.
