Creating a mental image of the weather using the weather radar is a complex task where experience is very
important. Areas to avoid are large areas with strong rain or smaller areas with tight color bands meaning there is
only a small area where the rain increases in density.
Keep in mind that strong fronts hide whatever is behind them. Use the manual tilt and gain to look below the
weather in front until ground clutter starts to appear. If the region directly behind the weather remains dark and
ground clutter appears on either side it indicates a possible radar shadow.
A quick way to test operation of the weather radar on a clear day is to tilt it down and increase gain with Ground
Clutter Suppression set to off. If you do not see ground returns the system is malfunctioning.
