| 摘 要： | 本文通过对１９９３年春季和春夏之交的O3浓度逐日变化、日变化和气象因子关系的分析，提出了影响O3浓度的主导气象因子和不同情况下形成高浓度O3的主要因子，提出了大风速对逐日变化中O3浓度特高及浓度日变化峰值的重要作用，并指出高温、低湿、小风并不是在所有情况都是促成高浓度O3的因子。另外，雾也可以成为近地面O3浓度增值的因素，主要原因是雾内湍流发展将高浓度O3大量输向下方。

| Abstract: | Based on the data observed in the 1993 spring and early summer, we analyze the relations of diurnal and the day-by-day variations of ozone with the meteorological factors and obtain the leading metoorological factors:in affecting the ozone concentration. It can be seen that the main factors in different sitllatiDns can play different roles in the formation of high ozone concentration. We find also the important effects of high wind speed on the high ozone value. High temperature, low humidity, or low wind speed may not always cause high ozone concentration. In addition, fog is also a factor to increase the ozone concentration near the ground because the evolution of turbulence in fog may cause a great ozone transfer towards the ground. |
