We are hoping these might move in, so we maybe might get precipitation if we are lucky to get. I agreed with you that we had long period of dry spell weather with hot days. So it wasn't really good month of November to early December. Really high pressure is over the bight to causes this band to be remain weak at the moment. So I am unsure. We'll wait and see how it going.

Tropical cyclones form in a maritime environment in which there is a relative abundance of cloud condensation nuclei (CCN), which to cut a long story short, leads to a relatively large number of small precipitation particles (compared to continental clouds). Another factor is that updraft speeds are generally a fair bit smaller in TCs than in severe thunderstorm convection - this also limits the diameter of the precipitation particles. This is critical, as it turns out that radar reflectivity is a very strong function of droplet diameter (something like ten to the sixth power). Also an important factor as you say Clyve, is the freezing level (which is probably higher than 15 000 in a warm-cored TC) - the largest reflectivities are produced by water coated ice particles - these are not present in TC precip. Finally, beam attenuation can be a problem in the widespread intense precip fields of TCs, even for S band (10 cm) radars. C band radars (5 cm) suffer badly in this environment. I'm not exactly sure, but I think all of Australia's weatherwatch radars around the coast are S band units (except for the two doppler radars in Sydney and Darwin, which are C band). Hope that helps... Cheers, Jonty.

Clyve. Radar reflectivity is the summation of ND^6 where N is the number of droplets within a radar "pulse volume" and D is the diameter of the droplets. From this you can see that D dominates radar reflectivity. In other words, storms that produce the largest drops (or rain coated hail or even large wet snowflakes) are those most highly reflective. Tropical storms, on the other hand, have a much larger number of droplets than do most "extratropical" convection but the diameters of these drops are small. Thus, the reflectivities of tropical convection are significantly lower reaching maximum reflectivities not uncommonly around 50 dBZ. Extratropical thunderstorms, especially those with hail will commonly reach 60 to 65 dBZ. Those storms with very large hail will sometimes reach reflectivities of 70 to extremes of 78 dBZ. In fact, if you were to be caught in a tropical storm with a 50 dBZ reflectivities, the visibility would be near 0. But in an extratropical thunderstorm, visibilities would be much better and rainfall rates would be much lower. This fact is one reason that in the states we do not list reflectivities as rainfall rates but rather by "reflectivity" in dBZ or power returned (to the radar) but on a log scale.

This might rotate around overnight and produce more rain over land tomorrow. Andrew. "W.A.

Heyas,
 
 
James Harris is on the storm that is currently hovering over the Hornsby area. He has followed this storm since Westmead and its witnessing some fantastic strikes and close too,  some 100metres away ((!!)), as well as some very nice hail. He is going to follow this storm as far as he can, and assures me that the video is getting a nice workout.
 
The BOM have been on the radio here informing people about this storm, seems they are getting more vocal with there warnings and advices since sydney has had many Severe storms in the region this season.
 
Another storm is situated to the south of Penrith and is also look rather nice.
 
All this on a Strikeone industrial action day ;). Go figure.
 
 
dann

The towers are leaning almost 45 degrees today. From the rear you cannot see anvil just updraft. I followed the storm up the F6 freeway, but turned home when I realised that the storm was already in Sydney. I don't chase in suburban streets and besides if I could not catch the thing at 110 kph i had no chance doing so at less than 60 kph.
