Summer time and heatwave management shows some cracks
SE Australian Heatwave
Melbourne sweltered through another heatwave, the first of 2017. Hope everyone survived the heat.
Temperature at Melbourne (Olympic Park) hit 36.1C at 3.30pm on Saturday. Of far greater concern, the overnight minimum temperature hovered at around 30C dipping down to 28.4C at 1.30am as the low point before rising to 30C at 9am Sunday. By early afternoon a cool change had moved through dropping temperatures to the mid 20s.
High night time temperatures disturb sleep and reduce physiological recovery for the next day. Night time is also when the Urban Heat Island effect is most pronounced as there is less atmospheric mixing, and zero vegetation transpiration to cool things down, unless there are stronger winds. The Bureau of Meteorology labelled the night as ‘oppressive’ citing both the higher than normal minimum temperature and higher humidity.
