Seasonal variability of surface ozone in Korea

Abstract:

Tropospheric ozone around East Asia include Korea impacts on air quality and climate, and has been increased with rapid economic growth. To better understanding, we analyzed seasonal variability of tropospheric ozone simulated by using GEOS-Chem. Surface ozone concentration in Korea has double peaks in April and September. Tropospheric ozone increases primarily associated with westerly wind anomaly in spring, with warming in summer and autumn, and with cloud depletion in winter. Surface ozone in spring elevated after mature-phase El Niño winters.

Key words: surface ozone, seasonal variability, Korea, East Asia
