Many of us also watched the huge cloud formations over the top end, and played around with various theories. The systems appeared out of nowhere, and moved in an anti clockwise direction, as opposed to the usual west-east trajectory. Obviously the forecasters were also a little concerned. The following captures show the formations in close up as captured by MTSAT and BOM.
A close up of the formation shows distinct radar signatures.
Other captures, which I presume are “thermals’,do not show the radar signature.
The red crosses show the spots where a beam was found to be strobing underneath the cloud formation. Do the glitches in the Navy radar captures, have anything to do with the spectrum beams and pencil beams?
The resulting weather a day later.
