On Feb. 24, 2021, the GOES East satellite captured this GeoColor imagery of grayish smoke plumes rising into the atmosphere across the southeastern United States.
In the wake of an historic winter storm and Arctic blast that moved across the central and southern U.S. this week, the NOAA-20 satellite caught the resulting power outages across southeastern Texas.
As a dip in the polar vortex continues to bring bitter temperatures to North America, the air over the northern reaches of the continent was so frigid on the morning of Monday, Feb. 8, 2021, that the GOES East satellite perceived the cold air along the ground as very cold cloud tops.
On Jan. 30, 2021, NOAA’s GOES East viewed a dust storm that blew across North Texas. With sustained winds of 30-40 mph, the dust was fast and thick enough to disrupt visibility for drivers as well as create poor air quality for pedestrians.
On Jan 28, 2021, NOAA’s GOES East satellite zoomed in on the eastern United States, and caught a few interesting weather phenomena.
The imagery above utilizes the Day Snow-Fog RGB product, which helps distinguish snow from clouds. In this case, vegetation appears green, water appears black, snow on the ground appears reddish-orange, high icy clouds appear pinkish, and moisture-rich clouds are a blue-white color.
On January 25, 2021, the GOES East satellite zoomed in on two low pressure systems swirling over the North Atlantic while cloud streets streamed off the North American coast.
On Jan. 13, 2021, the GOES West satellite captured this stunning GeoColor imagery of a strengthening mid-latitude cyclone near the Aleutian Islands as it approached the Gulf of Alaska. This low pressure system reached a low of 961 mbar with wind speeds of 74 mph and wave heights in excess of 40 feet, according to the National Weather Service Ocean Prediction Center.
Over the course of 48 hours from Dec. 30, 2020 to Jan. 1, 2021, the Himawari-8 satellite, operated by our partners at the Japan Meteorological Agency, watched a powerful low-pressure system intensify and move across the northern Pacific Ocean toward Alaska. Winds were recorded at more than 100 mph and some wave estimates were possibly higher than 45 feet over the open water.
NOAA has been using its satellites to monitor the massive iceberg, A-68A, in the South Atlantic Ocean since it broke off (“calved”) from the Larsen-C Ice Shelf in Antarctica on July 12, 2017. At the time, it was larger than the state of Delaware, and has remained one of the largest icebergs in the world.
On Dec. 17, 2020, the GOES East satellite zoomed in on a nor’easter that brought the season’s first significant snowfall across parts of the eastern U.S. The term “nor’easter” refers to an extratropical cyclone in the western North Atlantic Ocean where the winds blow from the northeast. These storms can batter the region with high winds, large waves, and heavy snow.
