NOAA's HYSPLIT Model on Fukushima Radioactive Aerosol Dispersion

as published by NOAA on March 1, 2012.


From NOAA's Science on a Sphere page:

The Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model was developed by NOAA to follow the transport and dispersion of pollutants in the atmosphere. In HYSPLIT, the computation is composed of four components: transport by the mean wind, turbulent dispersion, scavenging and decay. A large number of pollutant particles, which by convention are called "particles" but are just computational "points" (particles or gases), are released at the source location and passively follow the wind.

The 2011 Tohuku East Japan earthquake and resulting tsunami caused a variety of failures at the Fukushima Daiichi Nuclear Power Plant which resulted in radioactive emissions to the atmosphere. The earthquake occurred on March 11th at 14:26 Japan Standard Time (JST), the tsunami about one hour later at 15:41, and by 16:36 a nuclear emergency was reported. By the early morning hours of March 12th, radioactive emissions were occurring from the plant.


Notable Features

  • Particles with the highest radioactivity were released around March 15th

After seeing this, I wonder why the US is being so friendly to Japan, as it is clear the west coast of the US took a bad hit. You could almost see it as an act of war and Hillary annouced almost right away that Japan import products are more than welcom.
What is the catch here ? What did the US gained by this? Must be something. Any ideas?

One trillion dollar worth of US treasuries, for one.

Japan being next to China for another.

It was GE-designed reactors that blew up, for another.

That Roosevelt's naval blockade was an act of war but the US got away with it, for another.

I don't think the US has any moral authority left to say to anyone "it's an act of war".

Salut Ultraman,

Published in march 1, 2012 ? Not 2013 ?

Yes, 2012, sorry.

Way to go japan,you fucking retards.
Oh what's that? You're going to die 1st? GOOD!

@8:15 PM, reread your bible. Gloating over your neighbour dying first is a sin. Tisk tisk. Wishing anyone to die, especially the retarded, is a mortal sin. You are going to hell, I guess. I feel bad for y'all.

I have only sorrow and empathy for the citizens of Japan. That accident could have happened at any Nuclear site and still may. Let's pray we don't have to see this happen again. In one way or another we will all suffer the effects of this disaster.

there is no way to prevent the next catastrophic nuclear explostion. It will happen again, and several times, until we have enough.
Russia (again), US (again), France...
Given the risks, another explosion will occur within 12 years with good level of certainty.
And then, another with 20 years from now.
one large, one medium. Nuclear accident are now part of our every day life. We have accepted to die from a nuclear accident. Media introduce them to us as less problematic than oil spills.

Are you OK, Ultraman ?

Hi, Helios. I've been kind of tied up recently. Had to take care of the family member who is ill. Also somehow have to make money to support my non-profit work here (LOL).
