Northern Territory Seasonal Outlook – as at June 2015
Sourced from the Australian Bureau of Meteorology
http://www.bom.gov.au/climate/outlooks/
The national outlook for June to August 2015 indicates that:
 Drier than normal across the top end of the NT
 Wetter than normal across the southern NT in July
 Warmer than normal days more likely across the northern NT
 Warmer than normal nights more likely across the entire NT
Both the Pacific and Indian oceans are influencing this outlook. The El Niño in the Pacific (which
models indicate will strengthen) is having a drying impact on eastern Australia, while continued
warmth in the Indian Ocean, coupled with the El Niño in the Pacific, is tending to enhance
rainfall in southern WA.

Seasonal Indicators
Comments (sourced from the Australian Bureau of Meteorology)
El Niño Southern Oscillation (ENSO)
ENSO tracker raised to El Niño status on the 12 May 2015.
The 2015 El Niño continues to develop. Most oceanic and
atmospheric indicators are consistent with El Niño. International
climate models surveyed by the Bureau of Meteorology suggest
further warming of the tropical Pacific is likely, with sea surface
temperatures forecast to remain above El Niño thresholds for the
remainder of the year. Therefore, the ENSO Tracker status has been
raised to El Niño status on the 12 May 2015.
El Niño is often associated with below-average winter–spring rainfall
over eastern Australia and above-average daytime temperatures over
the southern half of Australia.
http://www.bom.gov.au/climate/enso/#tabs=Overview
Current outlook:
Warmer & Drier
El Niño Alert
El Niño ALERT Level
(El Niño status)
Indian Ocean Dipole (IOD)
http://www.bom.gov.au/climate/enso/#tabs=Indian-Ocean
Current outlook:
Neutral
Models suggest the IOD index will remain neutral throughout
winter.
The Indian Ocean Dipole (IOD) is currently neutral. Of the five
international models that provide IOD outlooks, two suggest a positive
IOD is likely later in 2015, with a third model just shy of thresholds.
A positive IOD is typically associated with reduced winter and spring
rainfall over parts of southern and central Australia.

* 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.

Risks:
-
The district has three experienced consecutive poor seasons. Pasture growth
during the past two quarters has slightly improved the amount of total
standing dry matter, but pasture levels are still low in many parts of the
district.

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.
