Analysis of Atmospheric Environment by using Numerical Simulation Models

Numerical modeling systems that represent physical/chemical processes in the atmosphere enable us to analyze meteorological phenomena such as the urban heat island effect and heavy rainfall, and air quality issues such as fine particulate matter (PM_2.5) pollution and photochemical oxidant pollution. The following figures present examples of numerical simulations, with the figure on the left showing the wind and rainfall distributions associated with a tropical cyclone simulated by a meteorology model and the one on the right showing the long-range transport of PM_2.5 from the Asian continent to Japan as simulated by an air quality model. Numerical models enable us to better understand the current situation, as well as the environmental variations, and to design effective environmental strategies for the future.
