Floods in the Midwestern Uni
…
| Title |
Floods in the Midwestern United States |
| Description |
The rivers of northwestern Missouri were still swollen in the wake of intense spring storms when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image on May 10, 2007. The image is made from a combination of infrared and visible light to make the floods more visible than they would be in a photo-like image. In this type of image, water is dark blue or black, clouds are light blue and white, plant-covered land is bright green, and bare earth is pink-tinted tan. Fires are outlined with red boxes. The Missouri River runs along the left edge of the image, then curves east along the bottom of the image. Though the most flooded regions were covered in clouds, a few breaks reveal that the Missouri was swollen far beyond its banks. Nestled in a bend in the river near the Nebraska, Kansas, and Missouri border is the town of Big Lake. The image shows that the river's curve has turned into a broad lake. The town was completely submerged in the flood when levees along the river broke, reported the Associated Press. [ http://www.cnn.com/2007/WEATHER/05/11/missouri.flooding.ap/index.html ] Beyond Big Lake, many communities along the Grand and the Platte Rivers and their tributaries have also been flooded or threatened by floods. All of these rivers are clearly running high in the image. MODIS captured the lower image on April 29, 2007, not quite a week before the rains began. By providing a clear view of normal water levels, the image illustrates just how extensively the rivers were flooded on May 10. Photo-like versions of both the April 29 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA3/2007119/USA3.2007119.aqua ] and May 10 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA3/2007130/USA3.2007130.terra ] images are available from the MODIS Rapid Response System.

Dust Storm in Texas
| Title |
Dust Storm in Texas |
| Description |
The same hot, dry, windy conditions that allowed grassfires [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13301 ] to rage throughout parts of Oklahoma and Texas at the end of 2005 kicked up dust at the beginning of the new year. On January 1, 2006, a dust storm approximately 500 kilometers (300 miles) across swept through northern Texas and into Oklahoma. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Aqua [ http://aqua.nasa.gov/ ] satellite captured this image on January 1, 2006. Swirling in a counter-clockwise direction toward the northeast, the dust storm appears in a light shade of tan, partially obscuring the view of the darker ground surface. The storm appears to start near the Texas-New Mexico border. Smoke from wildfires mixes with the dust in places. The "hot spots" where these fires rage on the ground appear in red, and some of the fires emit substantial plumes of smoke, especially two fires immediately south of the dust storm. Another fire, almost hidden by clouds, burns north of the dust storm. The hot, dry, windy conditions that prevailed in this part of North America in late 2005 set the stage for a dust storm in a couple different ways. Winds stir up particles on the ground and eventually suspend them in the air. Once aloft, dust particles can remain airborne even after wind speeds drop. Meanwhile, a dearth of rain can decrease vegetation cover, leading to extreme daytime heating of the ground. This heat causes an unstable boundary layer, the lowest 1 to 2 kilometers (0.6 to 1.2 miles) of atmosphere. An unstable boundary layer often encourages air to rise, carrying dust even higher into the air. According to the U.S. Drought Monitor at the University of Nebraska-Lincoln, significant portions of Texas faced drought conditions in late December 2005, including areas of extreme drought along the border with Mexico, and exceptional drought along the border with Oklahoma and Arkansas. Under these conditions, fires and dust storms could continue to threaten the region.

Snow Across the Western Unit

| Title |
Snow Across the Western United States |
| Description |
As much as 18 inches of snow coated the Sierra Nevada Mountains on November 27 and 28, 2004, stranding thousands of holiday travelers. In this Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]), captured by NASA's Aqua [ http://aqua.nasa.gov/ ] satellite on November 28, 2004, the mountains seem to have acted as a barrier to the storm, which moved in from the northwest, according to the National Weather Service. The east side of the mountains and the Great Desert Basin are white with snow, while the west side remains green. After this image was acquired, the storm moved east, blanketing Utah, Colorado, Wyoming and Nebraska with heavy snow.

Snowstorm in the American Mi

| Title |
Snowstorm in the American Midwest |
| Description |
The vernal equinox marks the start of spring in the Northern Hemisphere. But after a record-setting warm winter, the start of spring 2006 came with an ironic twist: a powerful snowstorm that blanketed most of the American Midwest in heavy snow. According to the Associated Press, snow fell as rapidly as two inches an hour in Illinois and Indiana, while in parts of Nebraska, total accumulations were as much as two feet (roughly 60 centimeters) of snow, closing sections of Interstate 80. In Colorado and Kansas, the same snow system also forced closings along Interstate 70 on March 20. The AP was also reporting that at least five deaths had been attributed to the snow in Colorado, Nebraska, and Texas. The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite observed the wake behind the storm at 12:55 p.m. Mountain Time (19:45 UTC) on March 21, 2006. In this false-color image, clouds appear white, snow and ice appear blue, and land colors vary from reddish tans to greens in areas of lesser or greater vegetation. While a thin layer of cloud covers much of the area where the heaviest snow fell the previous day, the long, wide swath of blue, occasionally visible through the thin cloud cover, shows the path of the snowstorm.
