Australian southern hemisphere forecast 7 February 2014

Australian southern hemisphere forecast 7 February 2014

The cyclone at 90 degrees east lasts for all of this model run. It ends up at 120 degrees east on T+150. At T+042 the jet that was feeding it has become an adjacent low at 40 to 60 east. Six hours later it bounces off the coast of Antarctica and skirts around the previous low system. The two joined have become a Blocking Low that reaches almost to Australia just south of Perth, quite a distance.

At T+090 it has come out of solution at about 140 east and goes on to skirt along the coast on the inside of the previous low. By T+132 it has arrived back at 90 degrees east, all but dissipated. Meanwhile the original low has reached 140 east and has darkened again as it hits the coast for the last time.

This run ends at 18:00 on the 13th of February. According to NASA, the new spell (a full moon) takes over on the 14th: Feb 14 at 23:53; virtually midnight the next day:
