The apparent-temperature model has been refined, and is applied to a range of Australian climate data to analyse the diurnal and annual pattern of normal effects of vapour pressure, wind speed and extra (solar and sky) radiation, and to combine these into maps and charts of apparent temperature. Results show that dry-bulb temperature sometimes over or underestimates the total impact of climatic norms by 10K. Equations are presented to enable calculation of direct and diffuse solar radiation in a clear sky at any time and place on earth. Sunshine is commonly the greatest modifier of dry-bulb temperature in Australia. Daily AT typically reaches its normal maximum before dry-bulb temperature, but seasonal variation of AT lags. -Author
