Wind erosion in NRM regions

Use the map to identify the months which were most, or least, affected by wind erosion in recent years (2000-2012). Data is available for most NRM regions of Australia. Use the knowledge to strengthen your wind erosion and ground cover management planning.

Information About

The wind erosion data is a record of which months suffered wind erosion most, and which didn't. The graph shows the percentage of the NRM region affected by varying degrees of erosion (from Very Low to Very High wind erosion). When viewed together as a time period (2000-2012), you can see which months/years were 'good' years, and which years suffered more erosion than usual.

Modelled Wind Erosion uses a numerical model called CEMSYS (Computational Environmental Management System) to create modelled monthly and annual wind erosion maps of Australia at 50 km resolution. For each pixel (50 km x 50km), a wind erosion severity level was calculated and classified as either very low, low, moderate, high or very high erosion. Then for each Natural Resource Management (NRM) region the percentage of land area affected by each wind erosion severity class was calculated. Read more about the project...

Information About

The dust history is a record of how dusty it's been in the last 50 years. The graph shows the total annual number of dust event days recorded for each year (1960-2011). A Dust Event Day (DED) is a day where at least 1 dust event was recorded. For each year, the total number of DEDs possible is 365 days, although nowhere in Australia is dust that much of a problem! When viewed together as a timeline, you can see which years recorded a lot of dust, and which years were least dusty.

Information

Information About

We've categorised dust events into 4 classes in order of severity: Moderate Haze; Severe Haze; Moderate Dust Storm; Severe Dust Storm. The graph shows the proportion of dust events (No. events %) observed per year, in each category. You can see, each year, what the main type of dust event was (e.g. 60% of events were moderate hazes). When viewed together as a timeline, you can see how the main type of dust event may have changed over the years. We show data for the time period 1960 to 2011.

Information About

The dust season is the time of year when dust activity is generally highest and most likely to occur. The graph shows the average number of dust events recorded for each calendar month. When viewed together as a whole year, you can see which months usually have a lot of dust activity. The dustiest months represent your dust season. We display the months of the year from July to June because most of the dust seasons in Australia occur between September and April.

Interested in more seasonal patterns? See the Regional data produced by the Modelled Wind Erosion project. There are monthly records for over a decade, which may reveal seasonal patterns in wind erosion extent and severity.

What is available

The following maps display Wind Erosion Rates for Australia which have been modeled for every month from Feb 2000 to Jun 2012. The wind erosion rate is the rate that soil is blown away by the wind. It is expressed here as mg/m/s

Each coloured pixel on the map is an area of land 50km x 50 km. You'll notice that wind erosion rates vary across Australia, and also from month to month.
