Who this tool is for
Farmers throughout Australia.
Questions this tool answers
- What is the chance of a season break happening by a certain date if I receive X mm of rain within Y number of days?
- What is the chance of getting more than X mm rainfall this coming season?
What this tool does
Rainman StreamFlow is a software package that uses historical weather records to forecast seasonal rainfall and streamflow.
Weather records used are from:
- 3800 rainfall locations
- 400 streamflow gauging stations
Forecasts are based on:
- the Southern Oscillation Index
- sea surface temperatures of the Pacific and Indian Oceans
Inputs
Historical data is included with Rainman StreamFlow but can be updated as follows:
- Rainfall – you can update monthly data for all stations automatically over the internet for free.
- Stream flow – you can manually update streamflow data if you have access to data from your state water department.
- All climate data – you can subscribe to SILO and update all daily climate records.
- You can enter daily data for your own farm.
Outputs
Rainman StreamFlow displays results as tables, graphs and maps. Figures 1 and 2 are examples.
Figure 1. The chance of rain within the next 3 months at Emerald
Figure 2. Rainfall in eastern Australia over the last 12 months
Reliability
Rainman StreamFlow predicts rainfall based on historical data. As the climate changes, the outputs will reduce in value and accuracy.
It is most reliable for eastern and subtropical Australia because:
- forecasting is mainly based on the Southern Oscillation Index
- forecasting does not consider climate drivers such as the Indian Ocean Dipole and the Southern Annular Mode
History
Rainman StreamFlow was previously known as Rainman and Australian Rainman.
It was developed by Queensland Primary Industries and Fisheries under the leadership of Dr Jeff Clewett, starting in 1988. It has been continually improved since then.
Support available
Queensland Primary Industries and Fisheries provides technical support, including free step-by-step tutorials.
