updated hourly. Very cool visual of earth wind and water temps. You can right click the globe and rotate to your preferred angle of view, and double click to zoom.

p.s. You may have already figured this out, but I'm playing with this app this morning.
If you click the Earth button (below) the detail screen comes up
Now, under Mode, you can click between Air and Ocean for wind or ocean currents, select height for air currents, temps, various projections, etc.
If you click your green circle onto a particular current or airstream, the current/air speed in m/s or k/h displays in the Earth button.
Also, if you've zoomed in, you can click the "O" under Projection, to return to the fully zoomed out projection.
Super Cool. Thanks for sharing!
