Using RADAR in Meteorology
RADAR in meteorology is really important when weather forecasters are making their decisions each day.  The images that are provided every 10 minutes at 46 locations around Australia show the location of where the rain is falling as well as showing how intense the rain is.

RADAR is an acronym standing for RAdio Detection And Ranging.  A Bureau of Meteorology RADAR operates by scanning the sky with pulses of radio waves.  These radio waves bounce back off any rain droplets that the beam encounters, which the RADAR can then detect and interpret them as a location (the time delay before receiving the return signal) and a rain intensity (the frequency of the return signal).

The Bureau of Meteorology has its RADAR images available on the internet for all of us to use when we are making everyday decisions...
Should I put my washing out today?
    Is it a good day to go for that bushwalk?
        When is the rain delay going to finish at the cricket?!

Of course, RADAR images are one part of the information provided to everyone by the Bureau of Meteorology to help us make good decisions about what we are going to do.  All of these are provided on their website http://www.bom.gov.au along with some handy tips on how to use their weather information. Take a look sometime!
