<![CDATA[Rainfall Anomalies at Radar Range Edges]]>In the past few days, I’ve noticed something unusual with rainfall patterns on radar images. At the outer edge of the radar range circles, the displayed rainfall often looks either more intense or less than expected.

For example, this was visible recently on the radar near Amsterdam, and a couple of days earlier on the one covering southwest England.

In the second case, the radar suggested heavier rain than what was actually happening at ground level. Perhaps precipitation was forming aloft but evaporating before it reached the surface?

In meteorology or on the racetrack, correctly interpreting the true nature of things amidst a mass of virtual data is a crucial skill. A very practical observation!

Without any screenshot it is difficult to imagine what you are describing.
