Northern Territory Seasonal Outlook – as at December 2014
Sourced from the Australian Bureau of Meteorology http://www.bom.gov.au/climate/outlooks/
The national outlook for December 2014 to February 2015 indicates that:
Drier than normal across the NT
Warmer than normal days and nights more likely across the NT
Climate influences include El Niño-like conditions in the tropical Pacific Ocean, and average to cooler than average waters surrounding northern Australia.
Seasonal Indicators Comments (sourced from the Australian Bureau of Meteorology)
El Niño Southern Oscillation (ENSO) http://www.bom.gov.au/climate/enso/
Current outlook:
El Niño Alert
El Niño ALERT Level (70% Chance)
El Niño-like impacts emerge in a number of areas
Many climate indicators remain close to El Niño thresholds, with climate model outlooks suggesting further intensification of conditions remains likely. Whether or not an El Niño fully develops, a number of El Niño-like impacts have already emerged.Indicators close to the El Niño thresholds include tropical Pacific Ocean temperatures, which have now exceeded El Niño levels for a month, and the Southern Oscillation Index, which has remained at or near El Niño levels for three months. Other indicators, such as tropical cloud, trade winds and rainfall patterns, have either remained near average or only temporarily approached thresholds. This indicates a typical El Niño ocean–atmosphere interaction may not be fully locked in.
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/#tabs=Indian-Ocean
Current outlook:
Neutral
The IOD index remains neutral.
The latest weekly index value to 30 November is +0.2 °C. Climate models surveyed in the model outlooks favour a continuation of neutral IOD values for the remainder of the year.
The IOD typically has little influence on the Australian climate from December to April.
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.
