Based on the observation of particulate matter concentration in Shenzhen from October to December 2022, the characteristics and influencing factors of New Particle Formation (NPF) events in autumn and winter in Shenzhen were explored. During the observation period, the average particulate matter concentration on non-NPF days was measured as 1.09×104 #/cm3, and on NPF days, it was measured as 1.57×104 #/cm3. The overall particulate matter concentration on non-NPF days was found to be lower than that on NPF days. The Shenzhen NPF event was characterized by low particle formation rate, low growth rate, and low condensation sink, which were consistent with clean and coastal areas both domestically and internationally. By using the standard of whether the mean condensation concentration during the time before dawn to early morning period was greater than 0.02s-1, NPF days were further classified into clean and polluted backgrounds. It was observed that the significant increase in boundary layer uplift and wind speed during the daytime created favorable conditions for NPF under polluted backgrounds. Under polluted backgrounds, NPF days were associated with stronger solar radiation compared to clean backgrounds. It was concluded that active photochemical reactions were the main driving force of the autumn and winter NPF events in Shenzhen. High temperatures, strong solar radiation, and low humidity were identified as factors controlling the formation of new particles, while high condensation and low wind speeds were found to control the loss of new particles.

以 2022年10~12月深圳颗粒物数浓度观测为基础,探究了深圳秋冬季新粒子生成(NPF)特征及其影响因素,观测期间非NPF天颗粒物数浓度平均值为1.09×104个/cm3,NPF天颗粒物数浓度平均值为1.57×104个/cm3,非NPF天颗粒物数浓度整体低于NPF天;深圳NPF事件呈现低成核速率、低生长速率和低凝结汇的特征,与国内外清洁、沿海地区较为一致;进一步以凌晨至清晨时段(0:00~9:00)凝结汇均值是否大于0.02s-1为标准,将NPF天分为清洁背景与污染背景,发现污染背景下NPF天的日间边界层抬升与风速显著增加为新粒子生成创造了良好条件,且污染背景下太阳辐射相较于清洁背景更为强烈;发现活跃的光化学反应是深圳秋冬季NPF事件的主要驱动力,高温、强太阳辐射、低湿与高凝结汇、低风速分别控制着新粒子的生成和损失.

以 2022年10~12月深圳颗粒物数浓度观测为基础,探究了深圳秋冬季新粒子生成(NPF)特征及其影响因素,观测期间非NPF天颗粒物数浓度平均值为1.09×104个/cm3,NPF天颗粒物数浓度平均值为1.57×104个/cm3,非NPF天颗粒物数浓度整体低于NPF天;深圳NPF事件呈现低成核速率、低生长速率和低凝结汇的特征,与国内外清洁、沿海地区较为一致;进一步以凌晨至清晨时段(0:00~9:00)凝结汇均值是否大于0.02s-1为标准,将NPF天分为清洁背景与污染背景,发现污染背景下NPF天的日间边界层抬升与风速显著增加为新粒子生成创造了良好条件,且污染背景下太阳辐射相较于清洁背景更为强烈;发现活跃的光化学反应是深圳秋冬季NPF事件的主要驱动力,高温、强太阳辐射、低湿与高凝结汇、低风速分别控制着新粒子的生成和损失.

Based on the observation of particulate matter concentration in Shenzhen from October to December 2022, the characteristics and influencing factors of New Particle Formation (NPF) events in autumn and winter in Shenzhen were explored. During the observation period, the average particulate matter concentration on non-NPF days was measured as 1.09×104 #/cm3, and on NPF days, it was measured as 1.57×104 #/cm3. The overall particulate matter concentration on non-NPF days was found to be lower than that on NPF days. The Shenzhen NPF event was characterized by low particle formation rate, low growth rate, and low condensation sink, which were consistent with clean and coastal areas both domestically and internationally. By using the standard of whether the mean condensation concentration during the time before dawn to early morning period was greater than 0.02s-1, NPF days were further classified into clean and polluted backgrounds. It was observed that the significant increase in boundary layer uplift and wind speed during the daytime created favorable conditions for NPF under polluted backgrounds. Under polluted backgrounds, NPF days were associated with stronger solar radiation compared to clean backgrounds. It was concluded that active photochemical reactions were the main driving force of the autumn and winter NPF events in Shenzhen. High temperatures, strong solar radiation, and low humidity were identified as factors controlling the formation of new particles, while high condensation and low wind speeds were found to control the loss of new particles.
