Image of day: Japan dries out

Although snow and rain fell over Japan yesterday, complicating the tsunami and earthquake clean-up effort, satellite imagery (above) shows the responsible storm (see the comma-shaped cloud mass northeast of Japan) pulling away to the northeast over the Pacific. In the storm’s wake, flow from the northwest and high pressure is building in.

The combination of this strong flow and high pressure is a good thing, as the flow will tend to push radioactive matter in the atmosphere offshore and the high pressure will prevent the matter from rising and mixing into the atmosphere for long-range transport. Jeff Masters further explains this in an excellent blog post.
