Autumnal equinox: Waters dry up (1 of 5)

April 1st, 2009

Autumnal equinox 11 of 15The pentad ‘Waters dry up’ starts Autumn rain. The maximum temperatures barely reach the mid-20s, but the days feel rentlessly hot and humid. The rain provides little to no relief. The rainfall in March 2009 totalled 21.8mm as measured at Bellambi weather station, which fell way short the mean rainfall of 79.8mm.

Whilst looking up these statistics I notice that there are huge differences between measured rainfall at locations not that far apart. Wollongong University averages 160.4mm in March for the past 30 years, twice as much as Bellambi, only 6 km away. Could the terrain cause such a discrepency? By the same logic, the rainfall in Austinmer must also deviate from Bellambi or Wollongong Unviersity. To gather data that truely represent this location, perhaps I do need my own weather station afterall.

    I should ask for a weather station for my birthday – plus the embroidered badge and hat. Weather observation can add to my daily routine.

    One thing that I really love about living on this side of the continent is the dramatic weather. The cloud formation and types are so varied. One of my favorite bed-time reading is a book called, ‘Weather’. I read it so many times but I just find different weather phenomena so amazing.

    In Perth where the weather almost always fine and the storms are short in duration, it has certainly be exciting experiencing the weather on the East Coast.
