Currents, Waves, and Tides | Smithsonian Ocean [23], Daytime heating and nighttime cooling of the hilly slopes lead to day to night variations in the airflow, similar to the relationship between sea breeze and land breeze. Wind in Australia is usually moderate. As with massing, orientation for thermal comfort is similar to orientation for daylighting, with some exceptions: First, the amount of sunlight that is optimal for daylighting is often not optimal for solar heat gain. Highly elevated surfaces can induce a thermal low, which then augments the environmental wind flow. Cape Horn, the southernmost land point of South America, has a characteristic strong west-wind, which makes crossings from East to West very difficult especially for sailing boats. For example, a northerly wind . Equator-facing sides of the building are well suited to capture and store the sun's heat via large windows and materials with high thermal mass, while sides facing away from the sun's path are not.

Like trade winds and unlike the westerlies, these prevailing winds blow from the east to the west, and are often weak and irregular. This map shows the maximum speed of sudden bursts of wind as forecast by weathermodels. Generally, orienting the building so that its shorter axis aligns with prevailing winds will provide the most wind ventilation, while orienting it perpendicular to prevailing winds will provide the least passive ventilation. rainfall, Decadal & multi-decadal From mid-May to early October, the strong prevailing winds of the southwest monsoon bring heavy rains and high humidity. Different regions and continents have different prevailing wind directions. To provide the best experiences, we use technologies like cookies to store and/or access device information.

If the slopes are covered with ice and snow, the mountain breeze will blow during the day, carrying the cold dense air into the warmer, barren valleys. For utilising the wind flow, buildings need to be oriented at an angle (usually 45 degrees) to the prevailing wind direction. Orientation should be decided together with massing early in the design process, as neither can be truly optimized without the other. Figure \(\PageIndex{6}\): Wind direction weather symbol.
