Forecasting Weather Patterns to Determine Radioactive Dispersion

What are we looking for? Surface Winds Upper-Level Winds Precipitation

Surface Winds: Damaged facilities lie on the Central-East coast of Japan Major population centres to the South and Southwest Notable population centres to the North Seoul and Shanghai to the West Therefore, we hope for Westerly surface winds, to direct radioactive material towards the Pacific Ocean

Why Precipitation? Radioactive material is scavenged by precipitation More specifically, radioactive particles mix with water vapour particles and are transported by weather systems When saturation occurs radioactive particles are redistributed in the form of precipitation.
