Japan Earthquake Hazard : Forecast of Winds
Forecasts of winds from East Asia to North America at different pressures, 900 mb (approximately 1 km above the ground), 700 mb (approximately 3 km above the ground) and 500 mb (approximately 5 km above the ground). The jet streams are 7-12km above the ground. The location of the Fukushima-Daiichi plant is marked with a dot in Japan. Forecasts are updated automatically for several days.
Winds at different pressure level:
Japan Earthquake Hazard : Forecast of Plume Propagation (RAMS HYPACT)
The following figure is a depiction of material transport following a hypothetical release from the Fukushima Daiichi Nuclear Power Station in Japan, This transport was computed using a "Lagrangian Particle Model". These type of models define a large number of particles released from a defined volume (the source). The particles are driven primarily by the wind field, the same as depicted above. There are on the order of 100,000 individual particles tracked in this simulation.
Possible Trajectories
Forecasts of forward particle beginning March 29 and extending to May 4.
The plots are produced using the NOAA HYSPLIT forward trajectories dispersion model.
Origin is the location of the Fukushima-Daiichi plant in Japan.
A hypothetical nuclear plume originating at different heights above the power
plant would follow the paths inolicated.

These meteorological and trajectory results depicted on this web page are forecasting general long-range atmospheric transport across the northern Pacific Ocean. These results are not necessarily indicative of actual radiation or radioactive material transport.
