1. Introduction Overhead transmission line icing refers to the phenomenon of freezing rain, rime, wet snow, and mixed icing on overhead transmission lines ( National Meteorological Bureau of China 1979 ). Ice accumulation on transmission lines is one of the most serious threats to power grid safety ( Kiessling et al. 2003 ; Pytlak et al. 2010 ). Extremely heavy ice loads and transmission line galloping (high-amplitude, low-frequency resonant oscillations of transmission lines, induced by the

urban climate, mesoscale meteorological models are used, for example, the fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5) and the Colorado State University Mesoscale Model (CSUMM) ( Pielke 1974 ). These models are based on the solution of a set of coupled governing equations representing the conservation of mass (continuity), potential temperature (heat), momentum, and water vapor to obtain data for the prognostic of meteorological fields

1. Introduction There are many uncertainties in numerical air quality modeling. Both the transport and transformation of air pollutants are directly and indirectly influenced by the modeling of the ambient meteorology. Furthermore, the distances over which many of these pollutants are subject to long-range transport by synoptic-scale weather phenomena can be rather large (e.g., Heidorn and Yap 1986 ; Greene et al. 1999 ; Lennartson and Schwartz 1999 ; Rohli et al. 2004 ). The longer the

( Nowak et al. 2006 ). Some particles that come into contact with trees are absorbed into the trees, but most remain on the surface of trees until they are resuspended into the atmosphere or are transported to the surface by precipitation or falling leaves or branches ( Nowak et al. 2006 ). A regional meteorological and air quality modeling study revealed that planting trees that emit low amounts of VOCs decreased tropospheric ozone concentrations whereas planting trees that emit large amounts of VOCs
