New animation from NOAA shows satellite imagery of Hurricane Sandy and how it followed the National Hurricane Center’s track issued at 11 a.m. EDT on Thursday, October 25 2012.
A 150-foot-deep meltwater channel carves its way through the Greenland Ice Sheet, a vivid sign of the glacial melting affecting the vast Arctic island.
Photographer James Balog’s assistant stands above the channel, whose black bottom is composed of cryoconite, made up of silt and soot blown from afar.

The Geostationary Operational Environmental Satellite 13 (GOES-13) captured this natural-color image of Hurricane Sandy at 1:45 p.m. Eastern Daylight Time (17:45 Universal Time) on October 28, 2012.
Note how a line of clouds from a continental weather system runs south to north along the Appalachian Mountains, approaching from the west to meet the offshore storm.

Summer Arctic Storm
In early August 2012, storms in the Arctic affected the motion of the sea ice north of Siberia and Alaska.
This animation shows the motion of the winds over the Arctic in conjunction with seasonal melting of the Arctic sea ice from August 1 through September 13, 2012, when the NASA scientists determined that the sea ice reached its annual minimum extent.
The surface winds, shown my moving arrows, are colored by the velocity. Slower winds are shown in blue, medium in green and the fast winds are shown in red.
June 2012 Wildfire Smoke Dispersion

The HYSPLIT wildfire smoke model run on June 29th, 2012 shows the cloud of smoke being emitted from many of the wildfires raging in the Western U.S. at that time.
The actual locations of these point-source pollutants can be seen as very high concentration smoke areas. The ability of the GOES satellite to detect aerosols is an important input to these models, as are the wind measurements derived from GOES infrared imagery.
A fire tornado, also know as a fire devil, is caused when a column of warm, rising air comes into contact, or causes, a fire on the ground.
Filmmaker Chris Tangey was able to capture images of a fire tornado that occurred in Alice Springs, Australia on September 17, 2012 . At the time, he was 300 meters away from the 30 meter high fire swirl which ‘sounded like a fighter jet’ even though there was no wind in the area.
