The Influence of Synoptic-Scale Wind Patterns on Column-Integrated Nitrogen Dioxide, Ground-Level Ozone, and the Development of Sea-Breeze Circulations in the New York City Metropolitan Area

Abstract The continually changing atmospheric conditions over densely populated coastal urban regions make it challenging to produce models that accurately capture the complex interactions of anthropogenic and environmental emissions, chemical reactions, unique meteorological processes, such as sea- land-breeze circulations. purpose this study is determine identify influence synoptic-scale wind patterns on development local-scale sea-breeze circulations air quality New York City (NYC), York, metropolitan area. This utilizes column-integrated nitrogen dioxide observations made during Long Island Sound Tropospheric Ozone Study (LISTOS) field campaign, ground-level ozone observations, HRRR numerical weather prediction model, trajectory model simulations using NOAA HYSPLIT model. A cluster analysis within modeling system was performed there were six transport pathways for NYC. Stagnant or weak out northwest resulted in worst Weak forcings associated with these allowed develop, resulting pollution being able recirculate mix freshly emitted pollutants. Significance Statement work understand how City, shows clean can be imported into region from rural England Atlantic Ocean, whereas polluted transported southwest. also importance strength winds allow strong develop all coastlines region, pollutants recirculating mixing contributing poor quality.
