Northern Territory Seasonal Outlook – as at September 2014
Sourced from the Australian Bureau of Meteorology http://www.bom.gov.au/climate/outlooks/
The national outlook for September 2014 to November 2014 indicates that:
Drier than normal across the southern NT in September and across the Top End in October
Wetter than normal in the Southern Alice Springs region over the October- November period.
Cooler than normal days and nights across the northern NT in September
Warmer than normal days more likely over the Top End in October.
Climate influences include a weakening negative Indian Ocean Dipole, and near- average to warm temperatures in the tropical Pacific Ocean.
Seasonal Indicators Comments (sourced from the Australian Bureau of Meteorology) El Niño Southern Oscillation (ENSO)
http://www.bom.gov.au/climate/enso/
Current outlook:
Neutral
El Niño ALERT Level (50% Chance)
ENSO remains neutral however El Niño possible in 2014 Despite some warming of the tropical Pacific Ocean over the past month, ENSO remains neutral. However, models continue to suggest an El Niño remains possible in 2014 although reduced slightly.
These model outlooks and current observations mean the Bureau’s ENSO Tracker although reduced from ALERT, remains at WATCH status, indicating at least a 50% chance (double the normal likelihood) of an El Niño forming in 2014.
El Niño is often associated with below-average rainfall over large parts of southern and eastern inland areas of Australia and above-average daytime temperatures over southern Australia. Such impacts can often occur while
an event is developing, as experienced in some locations over the past several months.
Indian Ocean Dipole (IOD) http://www.bom.gov.au/climate/enso/
Current outlook:
Wetter
IOD negative but weakening
The negative Indian Ocean Dipole (IOD) in the tropical Indian Ocean has shown signs of weakening. Waters to the north of Australia and in the Timor Sea have cooled over the past two weeks. All climate models surveyed by the Bureau indicate the IOD will continue to weaken, with neutral conditions likely to return during the austral spring.
A negative IOD pattern typically brings wetter conditions to inland southern Australia during winter and spring.

* In the Top End, pasture growth tends to be similar year to year regardless of rainfall. This is because pasture growth in the Top End is typically not water-limited and keeps growing until available soil nitrogen is exhausted. For this reason, any interpretation of growth being above or below the median should be treated cautiously because the actual difference between years is relatively small.

Pasture Information
The pasture and fire risk information in this document is derived from AussieGRASS.
AussieGRASS is a model that simulates pasture growth and standing biomass using climate data, vegetation mapping, fire history and regional estimates of grazing pressure. The model can be used to track simulated pasture growth and total standing pasture biomass at the landscape scale.
Note that the model does not use stocking rate data for individual properties. Where stock numbers are significantly higher or lower than typical for a district, model estimates of total standing dry matter may be erroneous.
