Overview of Chemical, Thermo-dynamical and Microphysical Properties of Fog in the Polluted Environment and its Modeling: Results From the WIFEX 2015-18
Abstract
By considering the national interests and key research issues it is important to consider how future research on fog modeling and forecasting will be organized so that it will most effectively address the issues that are important for public services in India. Therefore, Ministry of Earth Sciences (MoES), Government of India (GoI) has taken a multi-institutional lead in understanding broad aspects of winter-time haze and fog formation over northern regions of India, and for developing a suitable fog forecasting system that has relevance to all sectors and policy issues. The WIFEX project was designed to study the characteristics and variability of fog events in polluted environment and improve understanding some of the key questions on fog formation and dispersion. From a numerical modeling point of view the project was designed to improve understanding of the key parameters needed for physical parameterization of fog to improve its prediction. This paper will present the brief overview of microphysical, chemical and thermo-dynamical properties of fog in the polluted environment from the measurements carried out at Delhi international airport under the WiFEX campaign conducted during 2015-2018, followed by evaluation of fog forecast demonstrated using the IITM-WRF product. Finally, challenges in visibility forecasting for airport will be discussed.
