摘要
利用2016—2020年淮安地区环境监测站点资料和淮安国家基准气候站气象资料,研究淮安地区臭氧浓度与气象、环境的关系,并利用“注意力机制”下的Seq2Seq建立臭氧预报模型。结果表明:臭氧浓度与气象要素和环境要素的关系是多样的,臭氧与气温、风速整体上呈正相关,与相对湿度、气压、降水量、NO_(2)、CO、PM_(2.5)、PM_(10)整体上呈负相关;“注意力机制”下的Seq2Seq模型在预报4 h的臭氧浓度上效果较好,相关系数大于0.6。
The relationship between ozone concentration and meteorology and environment in the Huaian area are studied by using the data from the regional environmental monitoring stations in the Huaian and the meteorological data from the national reference station in the Huaian from 2016 to 2020,Seq2Seq under the"attention mechanism"is used to establish the ozone prediction model.The results show that the relationship between ozone concentration and meteorological and environmental factors is diverse,ozone and temperature,wind speed as a whole is positive correlation,it was negatively correlated with relative humidity,air pressure,precipitation,NO_(2),CO,PM_(2.5)and PM_(10);the Seq2Seq model under the"attention mechanism"had a good effect on the prediction of 4-hour ozone concentration,the correlation coefficient was greater than 0.6.
