Hmmm The best "long" term indicators for SE Australia rainfall is the Indian Ocean Dipole (IOD - see http://www.bom.gov.au/climate/IOD/about_IOD.shtml ) and unfortunately this was very positive in our spring (the critical period - see http://www.bom.gov.au/climate/enso/indices.shtml and associated links) which suggests that lower than average rainfall in central and southern Australia is likely to occur and this is further reinforced by an occurrence of el Nino (negative SOI - see http://www.bom.gov.au/climate/current/soi2.shtml and associated explanatory links). The weather map is certainly interesting and unusual - troughs going on all directions like that - but it is a short term phenomenon and not necessarily indicative of any long term weather pattern. -- Robert Hart [email protected] +61 (0)438 385 533 http://www.hart.wattle.id.au |
