National Weather Maps. Unit Settings Measurement preferences are saved . Wind direction changes due to the contour of the land. As the wind blows to about five degrees north and south of the equator, both air and ocean currents come to a halt in a band of hot, dry air. In the Great Plains: Prevailing Wind Erosion Direction. Example SW: Wind is blowing from South-West (SW) to North-East (NE). Third, the sun's heat can be stored by thermal mass, which the sun's light cannot. Wind speeds are 10-minute average wind speeds unless specifically There Different faces of the building get very different amounts of heat from the sun. overcast and heavy rain. It can also pull in daylight from sides facing away from the sun, without losing too much heat through lack of insulation (low U-value). The length of each bar on a wind rose is proportional to the frequency the wind comes from each direction. It's important when planning to be aware of access roads or other structures that may be impacted. It can even help the building contribute to the health and vitality of the surrounding social, and economic communities, by orienting courtyards or other social spaces to connect to street life. [18] The sea therefore has a greater capacity for absorbing heat than the land, so the surface of the sea warms up more slowly than the land's surface. In areas where there is rugged topography that significantly interrupts the environmental wind flow, the wind can change direction and accelerate parallel to the wind obstruction.
