Australian monsoon

The northern end of Australia receives most of its precipitation during its summer monsoon season, which typically occurs during December – March.

Forecast for wind and precipitation

This animation shows the forecast of precipitation (color shading) and horizontal winds at 850 hPa, which is about 1.5 km above sea level. The precipitation is the accumulation over the previous 6-hour period, in millimeters (1 inch = 25 mm), and winds are measured in m/s (1 m/s = 2.2 miles per hour). This is from a single deterministic forecast.

All forecast data is from the Global Ensemble Forecast System (GEFS) of the U.S. National Centers for Environmental Prediction (NCEP). All forecasts use an initial atmospheric state at the time indicated on the plot (note that 00Z is midnight Universal Coordinated Time, which is 9:30 am in Darwin, Australia or 8 pm the previous day in New York [EDT]).

Seasonal accumulation

The below plots show the daily rainfall and the total seasonal accumulation of precipitation for the “top end” of Australia (120-146E, 20-5S), compared to the historical average.
