The Characteristics of the Temperature,Humidity and Discomfort Index of Different Microclimate Zones on Typical Clear Winter Days with Cold Air Influence in Shenzhen

The characteristics of temperature,humidity and discomfort index of urban,marine,mountain and hill microclimate zones in Shenzhen on typical clear winter days with cold air influence were analyzed.It is important that developing intensive forecast in shenzhen.The results show that:on days with cold air influence the characteristics of the temperature,relative humidity and discomfort index of the four microclimate zones are different and similar.In particular the difference of land and marine microclimate zones are obviously.The temperature of the marine microclimate zone is the highest,and those of the urban,hills,mountain microclimate zones are from the second to the fourth.The relative humidity of the marine microclimate zone is the largest,the mountain the second,the urban and the hills' are the smallest.The marine microclimate zone is always the most comfortable,the urban microclimate zone is the second,the hills microclimate zone is the third,the mountain microclimate zone is the most uncomfortable.In addition,the marine diurnal variation of the temperature,the relative humidity and discomfort index are little.The marine variation during days with cold air influence are much less than the land.
