Research And Application Of The Relationship Between The Surface Meteorological Elements

The conventional ground meteorological parameters in China refer to the dry bulb temperature,dew point temperature,atmospheric pressure,relative humidity,wind speed and wind direction excluding solar radiation.The meteorological parameters play a basic and direct role in guiding the architectural design and energy consumption simulation evaluation of the area.In order to simulate and forecast building energy consumption,it is necessary to select representative hourly meteorological data of the whole year.However,due to the observation technology and other reasons,China is lack of recording complete hourly meteorological data.Therefore,it is very necessary to use the existing meteorological observation data to generate more accurate hourly meteorological data,so as to meet the requirements of building energy consumption simulation on the time scale of meteorological data.Based on the results of correlation analysis among three meteorological elements of dry bulb temperature,atmospheric pressure and relative humidity,the missing value filling model based on single element time series,the model for the development of dry bulb temperature and relative humidity based on its own elements,and the model for the development of atmospheric pressure considering both dry bulb temperature and atmospheric pressure are put forward.The reliability of the model is illustrated by the hourly data of Baoshan station in Shanghai.The maximum information coefficient(MIC)is used to analyze the correlation among dry bulb temperature,atmospheric pressure and relative humidity,as well as the same meteorological elements at different times.Two conclusions are drawn:(1)dry bulb temperature has a relatively strong correlation with atmospheric pressure;(2)the same meteorological elements at different times have a strong correlation.According to the above two conclusions,models to fill the missing values and for the development of dry bulb temperature,atmospheric pressure and relative humidity respectively are established.By filling the missing values of three stations in Shanghai,Beijing and Kunming,the optimal time length k value is determined to be 2or 3;according to the calculation of sunrise time and the occurrence time of daily minimum temperature,the daily minimum temperature is modified;according to the negative correlation between dry bulb temperature and atmospheric pressure,the model for the development of atmospheric pressure is modified.By comparing the hourly results generated by the model with the real values,the model has better prediction effect and can be applied to other meteorological stations.According to the quantitative relationship between wet bulb temperature,dew point temperature and dry bulb temperature,atmospheric pressure and relative humidity,the calculation models of wet bulb temperature and dew point temperature are established.The experimental results show that they can be used for the calculation of wet bulb temperature and dew point temperature.
