Prevailing wind direction is based on the hourly data from 1992-2002 and is defined as the direction with the highest percent of frequency. The dew point is the temperature at which condensationoccurs. Moisture is removed by orographic lift, leaving drier air (see foehn wind) on the descending and generally warming, leeward side where a rain shadow is observed. This moisture continues to flow eastward until orographic lift caused by the Coast Ranges, and the Cascade, Sierra Nevada, Columbia, and Rocky Mountains causes a rain shadow effect which limits further penetration of these systems and associated rainfall eastward. This orientation lets you consistently harness daylight and control glare along the long faces of the building. On the New South Wales coast, the winds are fairly inconsistent. Like trade winds and unlike the westerlies, these prevailing winds blow from the east to the west, and are often weak and irregular. Simultaneously, many urban areas are plagued by hazardous smog. Perth is the windiest capital, with an average wind speed of 15.6 km/h; Canberra is the least windy with an average wind speed of 5.4 km/h.
