The sun still the key in the sunshine state

And finally for the sunshine state it's off to south central Queensland where we look at a good range of data from Cunnamulla post office, Charleville airport and Bollon Mary Street.

A good range of data here going back to the mid 40's for time based temperatures with maximum and minimum temperatures going back to 1910.

Maximum temperatures for the area saw no significant increase (p = 0.056) although it is significant at the 10% level. The graph looks very random with exception to the last 5 years which have all seen a major increase in maximum temperatures. Minimum temperatures follow similar patterns to the max, but more amplified. Low temperatures in the 50's and since 1980 we have seen significant increases in temperature.

It is hard to come to any conclusions about midnight temperatures given their disjointed nature (missing years), however temperatures at 3am and 6am show no significant increase in temperature. Then as soon as the sun comes out we get major increases over time, with significant increases in temperature at 9am, Noon and 3pm. And then when the sun is losing it's power over temperature, no significant temperature changes were found at 6pm and 9pm.

Temperature differences between 3am,6am and the minimum have significantly increased, although interestingly have declined since 1990 despite still being around 0.25 degrees above the overnight temperatures. Thus once again indicating that minimum temperature is an inadequate gauge of overnight temperatures, and that minimum temperatures have been increasing at a larger rate as compared to overnight temperatures.

9am temperatures increased significantly (p = 0.01) over time as opposed to 6am temperatures (although the relationship is not as strong as previous places studied). And predictably, the same happened in the reverse; when the sun loses it's power temperature anomalies at 6pm have decreased over time when compared to 3pm.

Thus indicating once again, that the only reason why temperatures have increased in southern queensland over the last few years is due to the sun.

Ahh sunny Queensland. It's not called that for no reason. Onto New South Wales next.
