摘要

该研究旨在分析九年来的三种现象-雾，雾和霾及其对海得拉巴拉吉夫甘地国际机场空中交通的影响。我们利用机场常规气象观测、卫星图像、返航轨迹、重新分析数据和气候学图表等资料，分析持续时间较长的能见度下降事件。气候学资料主要解释了长时间的雾事件。稳定的大气层、行星边界层中水分的可用性、微风、辐散(向下运动/下沉)和辐射冷却支持了雾的形成和维持。低能见度影响了研究地点的空中交通，造成航班延误和相应的经济损失。

Determinants and Impact of Fog, Mist and Haze phenomena: The case of Rajiv Gandhi International Airport, Hyderabad

The study aims to analyze the three phenomena - fog, mist, and haze over nine years and their impact on air traffic at Rajiv Gandhi International Airport, Hyderabad. Longer duration events of deteriorated visibility are analysed using surface in-situ data from the airport routine meteorological observations, satellite imageries, backward trajectories, reanalysed data and aerological diagrams. The climatological data predominantly explained long-lasting fog events. The stable layers of the atmosphere, availability of moisture in the planetary boundary layer, light winds, divergence (downward motion/subsidence), and radiational cooling supported the formation of fog and its sustenance. Low visibility disrupted air traffic at the study site by way of flight delays and consequential economic loss.
