These verbs paint a vivid picture of the wind's dynamic and sometimes destructive power. The phrase "windswept" describes a landscape exposed to the elements, often evoking a sense of isolation and exposure. Furthermore, the vocabulary associated with wind varies based on regional...
The exposure category for many meteorological stations in China is temporally varying because of the rapid urbanization and revitalization of cities in last few decades. This causes difficulty in correcting or adjusting the surface wind observations to a standard exposure condition, especially if the ...
The basic wind speed corresponds to a 3-second gust speed at 33 ft (10 m) above ground in Exposure Category C; 图6-1中的基本风速,单位英里/时(米/秒)。基本风速相当于地面方位C处3秒阵风通过33英尺(10米); V1 = unpartitioned internal volume ft3 (m3);未被分割的内容积,单位英尺3(米3);...
The results also show that the interference effects among three prisms are more significant than those between two prisms, and the tested IF among three prisms, in exposure category B, has a respective increase of 109% across wind and 6% along wind over those between two prisms. Because the ...
local building departments, will typically provide statutes for both wind speed and exposure categories for their county. However, some jurisdictions will provide only wind speed and require the building’s designer to assess the exposure category based on the specific location. Many counties will use...
Plan Elevation 190 Step 1: Building risk category: Based on Table 1.5-1, building risk category is IV. Step 2: Basic wind speed: It is given as 100 km/hr. Step 3: Building wind load parameters: Kd 0.85 (wind directionality factored evaluated from Table 26.6.1) Exposure category is D ...

The analysis included wind statistics, tower shading, an exposure category classification using satellite images, the effect of atmospheric stability on the wind profile exponent, and a correlation matrix of wind speed to gain an understanding of the meteorological correlation between long-term weather ...
