Does anybody out there know the exact positioning of GMS5? I have been looking for it's lat lon and altitude (above the surface). I have found that it is lat 0, long 140E and 35,800km above the earth. Does anybody have info which is more accurate than this?

To add to Michael's comments about this Spring. With very little storm activity or rain over the last 8 weeks in this region, it is starting to feel like what I would associate as a stereotypical El Nino year - not the La Nina that we are supposedly heading into. I guess it show the complexity of our weather determinants - there is a lot more to it than just Pacific Ocean currents and the Southern Oscillation.

Hi Laurier, The file for the radar you are looking for is IDR281.gif. As I'm internal to the bureau I can't tell whether it's available outside - though I can't see why not. Try using the URL you now use, substituting the above name. As I'm not in NSW and no longer active in forecasting I'm not aware of how long it's been operating, but it must be after September, going by the minutes of a NSW RFC meeting.

Pushing but not quite there. Came in at -1 in the end (rounded). The record is -1.8 (28/11/1967). It has been below 0 in 12 out of the 59 Novembers in the record (most recently in 1996). There are a number of below-zero obs in the early part of November but only two (both in 1967, and interestingly, the two lowest November obs) after the 11th. 6 in Melbourne this morning - lowest November min since 1993. -2 at Ararat (not a record).

With only 1 month till Summer......one is wondering........... The last big La Nina, in 1988-89, also took its time - on that occasion the SOI peaked in late 1988, but the major rainfall anomalies in eastern Australia were in autumn 1989 - in fact, that period included the exceptionally dry and hot month of October 1988. There was quite a bit of local storm activity in late 1988, but this was rather patchy (there was a memorable downpour in Melbourne on Christmas Day). 1973-74 also peaked, rainfall-wise, in early 1974, although 1973 was a wet year too.

So far the seasonal outlook statement is worded 'positive SOI numbers at this time of year are linked with above average numbers of tropical cyclones in the Australian region during the northern wet season'. (By the way, those who follow the Seasonal Outlook - which is available through http://www.bom.gov.au/climate/ - may have noticed that it is now being issued two weeks before the start of the outlook period, rather than at the start of the period as was the case in the past). No-one has made any comment on severe thunderstorm risk - I'm not aware of any work done on ENSO/thunderstorm links (as distinct from ENSO/rainfall links - the intuitive conclusion might be that higher rainfall implies more severe thunderstorms, but intuitive conclusions don't always work in this game), which doesn't mean that there isn't any.

Most of the coupled models (here and overseas) are expecting cold anomalies to persist for the next 6 months - after that they start to diverge. For what it's worth the BMRC model is expecting cold anomalies to persist throughout 1999, returning to neutral in early 2000. A good collation of assorted model forecasts can be found in the Experimental Long-Lead Forecast Bulletin (http://www.iges.org/ellfb/). All the usual suspects can be found there.

I remember reading this summary of work being done by Ivan Kuhnel at the National Hazards Reseach Centre at Macquarie uni "..Ivan is working currently on a detailed climatological analysis of the NHRC hail data set for Sydney. This investigation focuses mostly on the interannual variability of the data and the relationship between the hailfall activity and large-scale atmospheric patterns, such as the ENSO..." {http://www.es.mq.edu.au/nhrc/current1.html} Although, when the results of this study become available I guess we might have some idea, logically (and I'm not a meteorologist), I can't see how would ENSO would have such a strong effect on the development of thunderstorms/severe thunderstorms in eastern Australia, unlike tropical cyclones where their development is directly related to ocean temperatures. While I guess all thunderstorm enthusiasts understand the importance of the warm gulf stream as a source of deep moisture for fueling the mid US dryline and frontal storms, I can't see that the same situation exists here and I'm less sure of how ENSO affects ocean temps at more temperate latitudes such as where the Sydney storms feed off. You might remember that Michael Thompson and Jimmy Deguara discussed earlier on the list the alignment of the low pressure troughs such that they were dragging dry air in. It would seem that regardless of how warm and moist the pacific air was during this period and how unstable the atmosphere was, none of the moisture would have been available for convection anyway. However just to contradict myself I noticed that the last signficant turnaround from -ve to +ve SOI values occured in mid 1995, although it has not been as pronounced as the current one (follow the SOI link in the BoM's SILO section) - the following spring summer (1995/6) was the best storm season I can recall in Sydney since I became interested in thunderstorms. Perhaps it's just coincidental.

I remember being at Foster in late November and a storm gave an impressive lightning show for 3-4 hours in the wee hours of the night, but very little precipitation fell. I think several fires started in the Coonabarabran region that night from strikes. This week is only going to make us even more dissappointed, although a light thundery may pop up west of Canberra late in the week.

He certainly does not seem to be taken seriously by professionals. However his forecasts appear regularly in highly regarded publications such as The Land. I have not seen any long term analysis of his accuracy. His forecasts tend to be worded fairly vaguely which would make any kind of statistical analysis very difficult. So, the legend lives on....
