La Nina the Drought-Breaker

By jennifer
December 7, 2007

No change in atmospheric CO2, but:

THE drought-breaking La Nina weather pattern has finally kicked in, bringing flooding rains along the eastern coast and filling the tributaries that feed into the dying Murray-Darling river system.

Forecasters are predicting a wet summer and autumn but remain unwilling, at least officially, to call the end of the worst drought in living memory. And they warn it would still take rains of "biblical proportions" to fill the dams of cities and towns.

Drought-breaker La Nina kicks in for wet summer

Good Causes

  1. Some extracts from the Perth Gazette.
    "Rain is much wanted in the pastoral districts" May 1838
    "... serious apprehensions are entertained by experienced flock owners that considerable losses will take place among the larger flocks owing to the drought in the course of the summer. This, we believe, is the first season since the formation of the establishments over the hill - a period upwards of seven years - that such apprehensions have been warranted ... there appears to have been a diminution (of rainfall) beyond the Darling Ranges," October 1838
    "The country is unusually dry." January 1839
    "Hot and dry weather severely affected sheep farmers, 50 per cent. lambs were lost and ploughing retarded." May 1856
    "The breakup of the long-continued drought occurred" May 1858

  2. Back on theme, “Forecasters are predicting a wet summer and autumn but remain unwilling, at least officially, to call the end of the worst drought in living memory. And they warn it would still take rains of "biblical proportions" to fill the dams of cities and towns”.

    Try digging holes through this fragile green stuff. At this point there is nothing underneath to last through summer.

  3. Arnost c’mon, oranges v apples Jan 07 v Oct 07 indeed! Wait till Jan 08 data is up to scratch with some summer heat downunder backed by the extra degrees round oz.

    hey regardless of 07-08 figures, Jan is the swinging month year to year

  4. Gavin - I'm not quite sure what you want me to explain... NCDC hasn't got out Nov numbers yet, but even basing it on the ones you provide then Jan to Oct the decrease is almost 0.4C...

    Jan 2007 0.8328 => Oct 2007 0.4826

    It is expected that Nov will be cooler than Oct (both MSU and even GISS temps took a big downtick in Nov)

    One right back at you - please explain why should we ignore HadCRU and satelite temps (which both match the sonde temps) and rely on NCDC / GISS which is some 0.2 - 0.3C higher?

    Oh, by the way - did you know that when adjusting for UHI and such USHCN / GHCN (which both NCDC and GISS base their temps on) they conveniently increase the temps by something like 0.2 - 0.3C...?

  5. Helen: No rainfall charts needed here. Unfortunatly drought prevails. Wild poppies are a great indicator of surface moisture. Catchment dryness can also be measured while pulling up weeds by hand.
