Comparison of Wind Fields in the ABL over Big City and Nearby Rural Site by Simultaneous Sodar Measurements

OSTI ID:891154
Simultaneous measurements of wind profiles in the Moscow downtown and in a contiguous rural area were carried out in autumn and summer time. The urban-rural wind speed difference strongly depended on thermal stratification, strength of wind, and altitude. On average, wind speed in the downtown was less than in the rural area, with 1-2 m/s difference below 100 m and 0.5-1 m/s at levels above 200 m; wind direction difference was within 10-20 degrees. Sometimes the differences were many times higher than averaged values.
