Rainman StreamFlow is a decision-support tool that helps farmers to predict rainfall at a specific location within a specified time period and can be used to:

  • Analyse records for individual locations for seasonal, monthly and daily patterns.
  • Forecast seasonal rainfall based on the Southern Oscillation Index or Sea Surface Temperatures.
  • Use group locations for spatial analysis.
  • Import monthly, daily rainfall and streamflow data.
  • Print results as tables, graphs, charts or maps.

Rainman StreamFlow is a software package that uses historical weather records to forecast seasonal rainfall and streamflow. Weather records used are from 3,800 rainfall locations and    400 streamflow gauging stations. The forecasts are based on the Southern Oscillation Index and sea surface temperatures of the Pacific and Indian Oceans.

The type of outputs from Rainman are shown below. These indicate rainfall in eastern Australia over the previous 12 months, as well as the chance of rain within the next three months at Emerald, Qld.
