Abstract

During the fire season of 2023, extreme continuous wildfires in Canada exported smoke to distant areas. On June 6–8, record-breaking smoke concentrations impacted human health and the environment in New York City (NYC) and its surroundings. In this work, for the first time, we incorporate Lagrangian airmass trajectories with Copernicus Atmospheric Monitoring Service (CAMS) forecasts to trace back the origin of the smoke in NYC and identify the weather systems governing its transport. We locate the main smoke plume which originated from fires in Quebec. The smoke traveled at a height of about 500 hPa southward and descended slantwise to NYC behind a deep cyclone over the east coast. A second peak in smoke concentration in NYC emerged by air that circulated around the cyclone back to the city, collecting smoke again from the fires in Quebec. Smoke from the major fires in western Canada did not contribute significantly to the NYC event but was transported at tropopause level toward Europe. The findings highlight the critical role of synoptic-scale systems in the transport of wildfire smoke.

2023年6月,纽约破纪录的空气污染事件中的烟雾来源
在2023年的火灾季节,加拿大极端连续的野火将烟雾输送到遥远的地区。6月6日至8日,破纪录的烟雾浓度影响了纽约市及其周边地区的人类健康和环境。在这项工作中,我们首次将拉格朗日气团轨迹与哥白尼大气监测服务(CAMS)预报结合起来,以追溯纽约市烟雾的起源,并确定控制其运输的天气系统。我们找到了来自魁北克大火的主要烟羽。烟雾以大约500百帕的高度向南移动,并在东海岸上空的深层气旋后倾斜下降到纽约市。纽约市烟雾浓度的第二个高峰出现在气旋周围的空气中,这些空气再次聚集了魁北克大火产生的烟雾。来自加拿大西部大火的烟雾对纽约的事件没有显著贡献,但在对流层顶被输送到欧洲。这些发现强调了天气尺度系统在野火烟雾传输中的关键作用。

期刊介绍: Atmospheric Science Letters (ASL) is a wholly Open Access electronic journal. Its aim is to provide a fully peer reviewed publication route for new shorter contributions in the field of atmospheric and closely related sciences. Through its ability to publish shorter contributions more rapidly than conventional journals, ASL offers a framework that promotes new understanding and creates scientific debate - providing a platform for discussing scientific issues and techniques. We encourage the presentation of multi-disciplinary work and contributions that utilise ideas and techniques from parallel areas. We particularly welcome contributions that maximise the visualisation capabilities offered by a purely on-line journal. ASL welcomes papers in the fields of: Dynamical meteorology; Ocean-atmosphere systems; Climate change, variability and impacts; New or improved observations from instrumentation; Hydrometeorology; Numerical weather prediction; Data assimilation and ensemble forecasting; Physical processes of the atmosphere; Land surface-atmosphere systems.
