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!
