The Albany sounding shows very cold air at the Earth’s surface where it is usually warmest (inversion). Between 820 mb and 595
mb the temperature increases or is isothermal.
What radiation fluxes were in play on that morning?
Correlation Coefficient
A correlation coefficient is very useful for assessing whether two variables might be connected in some way. The variables might
include temperature but they can be anything.
This is a morning sounding from southeast Queensland. Notice the dry lower atmosphere and light wind.
Summary of the radiational fluxes causing abnormal heat in Queensland on Feb 7, 2006
1. Summer insolation is very high. At that subtropical latitude, the angle of sunlight is almost directly overhead.
2. The atmosphere was dry so less LW was absorbed by water vapor.
3. The lower atmosphere was quite warm, probably due to warm air being brought in by a High-pressure system.
5. The hottest part of Queensland was inland so the land mass absorbed SW and not much of the energy was used to evaporate water from the dry soil.
4. That High also meant no clouds to reflect SW and absorb LW from the insolation.
Primary cause of the heat wave:
A quasi-stationary high pressure system set up over the North Sea. East winds over western Europe cut of the usual ocean moderation.

Daily Maximum Temperatures,
Daily Precipitation
Warm Highs in summer are under warm upper air ridges.
