北半球春季大气臭氧年际变化特征及其对大气温度和环流场的影响

北半球春季中高纬地区大气臭氧总量具有明显的年际变化,正（负）异常时,与其相应对的流层平均温度、位势高度场均为负（正）异常,平流层异常情况相反,北大西洋地区大气臭氧年际异常与其他地区正好相反,这是区别大气臭氧与其他温室气体影响的重要标志。

Features of Atmospheric Ozone Interannual Variation in Spring of Northern Hemisphere and Its Effect on Temperature and Circulation

The spring total O-3 in the atmosphere exhibited substantial interannual change over northern extratropics, which exerted crucial influence on atmospheric temperature and circulation characteristics. During the intense(weak) years of total ozone, for most of these latitudes, especially in Asia, the positive(negative) anomaly of the quantity was related to the negative (positive) anomaly mean temperature and geopotential height in troposphere and vice versa for in stratosphere, and instead, negative(positive) anomaly of the gas happened over the belt stretching from the Hudson Bay to the northern North Atlantic to West Europe and was in association with the positive(negative) anomaly of tropospheric(stratospheric) mean temperature and geopotential height (but the latter took place only in most cases). Obviously, the opposite features of the total ozone anomaly at extratropics over Asia and the northern North Atlantic represents an innegligible indicator of the impact of ozone, the negative (positive) and positive(negative) anomaly occoured in troposphreic mean temperature over North/East China and West/South China, respectively, just in opposition to the condition in the stratosphere.
