Study On The Calculation Method Of Typical Meteorological Year Parameters Of Marine Climatic Conditions

China's oceanic land is vast in area,rich in resources,and has a large climatic difference.The South China Sea region is at the forefront of China's marine development.The construction work in this area is of strategic importance for future marine development.However,due to its remote location,fresh There are studies on building energy efficiency in the South China Sea area,and the lack of meteorological parameters in the South China Sea area is more serious,so it is impossible to effectively guide building energy efficiency design in building design,so the South China Sea is selected as the research area.Aiming at the above-mentioned current situation,the thesis studies the calculation methods of typical annual meteorological parameters in the South China Sea.First,through the analysis of building energy consumption principles,several meteorological parameters that have the greatest impact on marine building energy consumption are obtained: air temperature,relative humidity,wind speed,and solar radiation.Satellite data can provide meteorological data for a long period of time and an average of six times per day;cmip3's climate simulation data can also obtain meteorological data for any location in the world.Therefore,this article collected satellite data from 1987 to 2016 and climate simulation data in the same period.Satellite data provides sea surface temperature data,and air temperature data cannot be obtained directly.Therefore,sea surface temperature inversion of air temperature is also needed.In this paper,BOWEM ratio method and empirical coefficient method are used to invert air temperature.The satellite data cannot directly provide solar radiation data,so the temperature difference model after the altitude parameter correction is selected to calculate the solar radiation value in the South China Sea and the solar radiation value in the climate simulation data is collected.Secondly,in order to verify the reliability of the data,the temperature,humidity and wind speed data of the ship's nautical measured data were collected.Navigation data has the problem of discontinuous time and space,so it can only be used as a data scale to verify the accuracy of satellite data and climate simulation data.After comparing and verifying the nautical data,it is found that the empirical formula for retrieving the air temperature is smaller than the MWE of the BOWEN method and the model stability is better.For temperature,humidity,and wind speed,the MPE of satellite data is smaller than that of climate simulation data,and the model stability is higher.However,the temperature and relative humidity to be obtained from the satellite data need to be further calculated,and the process is more complicated;the climate simulation data can directly obtain the required parameters.According to the solar radiation value provided in the METEONORM software,the solar radiation data obtained by comparing the climate simulation data and the solar radiation data calculated by the temperature difference model are found: the solar radiation calculated by the temperature difference model is close to the climate simulation MPE,and there is no obvious advantage or disadvantage.Finally,in order to explore the relationship between various parameters and air conditioning energy consumption,we selected four cities with longitude and latitude close to the South China Sea,Hong Kong,Singapore,Manila and Kuala Lumpur,and changed the four meteorological parameters of temperature,relative humidity,wind speed and solar radiation in the meteorological file.Simulate building air conditioning energy consumption.Through the fitting equation of energy consumption error and parameter error,the relationship between building energy consumption error and each parameter error is obtained.It is found that the temperature error has the greatest impact on the building energy consumption error,the energy consumption error is about four times the temperature error;the second is humidity,the energy consumption error is about 0.7 times the humidity error;the energy consumption error is about 0.5 times the radiation error;the energy consumption error is about It is 0.01 times the wind speed error.The South China Sea region is a region of strong radiation.Due to its maritime climate,building energy consumption is different from the inland area,so by simulating the cooling energy consumption in July in the domestic strong radiation region,it is cooling in July with the four cities of Hong Kong,Singapore,Manila and Kuala Lumpur.A comparative analysis of energy consumption shows that the summer cooling energy consumption in strong radiation areas is affected by temperature and humidity in addition to solar radiation.In summary,the three parameters of temperature,humidity,and wind speed are better obtained by satellite data with higher accuracy.For solar radiation,a better method is the solar radiation value provided by the climate simulation data,because the accuracy of the temperature difference model after the elevation parameter correction has no obvious advantage over the climate simulation data,but the calculation method is more complicated.The thesis studies the method of obtaining meteorological parameters in the South my country Sea more clearly,and studies the relationship between the meteorological parameters and building energy consumption in the South China Sea.Provide accurate data and theoretical basis for the meteorological parameters of building energy conservation in the South my country Sea.
