For the purpose of the improvement of the thermal environment in a built-up area in summer night, the appearance frequency of cold air drainage and its influence distance in a built-up area were investigated based on observations. When large scale land and sea breezes are weak, the frequency of the cold air drainage is high. When the wind velocity at 100m height was less the 4m/s, 91% in total time of the cold air drainage appeared. The velocity of. the cold air drainage at the mouth of the valley was about 2m/s. When large scale land and sea breezes are strong, the cold air accumulated in the valley is mixed and blown out. As large scale land and sea breezes became weaker, the influence distance of the cold air drainage in the built-up area was expanded.
