兰州市逆温时空分布特征及其与API首要污染指数的关系
The Spatial and Temporal Distribution Characteristics of Inversion and Their Relations with API Primary Pollution Index in Lanzhou City
摘要
Abstract
Based on the sounding data from Yuzhong weather station,the change features of inversion and their relations with API primary air pollution index in Lanzhou City was analyzed during the period of 2006-2013.The results showed that the ground inversion at 07:00 had the most significant impact on API primary air pollution index,the ground inversion was most serious in winter,followed by autumn and summer was most weak,from October to January of following year relatively concentrated,the ground inversion duration of more than ten days main occurred in November to February of following year.When the inversion temperature was less than or equal to 3 ℃ would bring the negative contribution to the air quality increased significantly,more than 700 m and less than 900 m the probability of pollution days was higher than the cleanup days.The average of API primary pollution index was 93 when the inversion duration of 2.0 to 5.0 days,at the same time,the probability of pollution days was 26％,for 5.1 to 15.0 days was 107 and 39％,and more than 15.0 days was 141 and 68％.关键词
