NASA Provides Satellite Views of Maryland's Severe Weather Outbreak

08.06.2012
On Friday, June 1, 2012 severe weather generated 9 weak tornadoes across Maryland, according to the National Weather Service. As the system that generated them approached, NASA's Aqua satellite gathered information about power behind it. NASA also created an animation of the severe weather as it was seen from NOAA's GOES-13 satellite.

The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite provided both a visible and an infrared look at the severe weather that moved into Maryland on June 1 and generated an astounding number of tornadoes – nine in all.

Aqua passed over Maryland on June 1 around 18:53 UTC (2:53 p.m. EDT) and AIRS captured data on temperature and cloud heights. The infrared imagery showed that the major activity was located in West Virginia and heading eastward toward Maryland. When cloud temperatures get colder, it means that clouds are getting higher. Building clouds indicate a lot of "uplift" in the atmosphere and stronger thunderstorms.

Ed Olsen of the AIRS Team at NASA's Jet Propulsion Laboratory, Pasadena, Calif. said that the AIRS imagery showed "The center of most intense activity over West Virginia appears to have cloud top temperatures between -27 and -45 Fahrenheit (-33.1 and -43.1 Celsius / 230 and 240 Kelvin), meaning that the cloud tops (assuming U.S. Standard Atmosphere) are between (4.6 and 5.6 miles) 7.5 and 9 kilometers high."

The data from the AIRS instrument is also used to create an accurate 3-D map of atmospheric temperature, water vapor and clouds, all of which are helpful to forecasters.

NOAA's GOES-13 satellite was providing real-time visible imagery of the severe weather outbreak when tornadoes were touching down around Maryland on June 1. The NASA GOES Project, located at NASA's Goddard Space Flight Center in Greenbelt, Md. combined the GOES imagery to create an animation of the severe weather outbreak. The animation that runs almost eight seconds shows the movement of the severe storms from 1:45 p.m. to 7:45 p.m. EDT (1745 UTC to 2345 UTC). The colorized full resolution uses the GOES visible data of the clouds, overlaid on a U.S. map created by imagery from the Moderate Resolution Spectroradiometer instrument (MODIS), an instrument that flies onboard both the NASA Aqua and Terra satellites.

The animation shows a cold front approaching from the west spawned severe storms along the U.S. East Coast, including 9 weak tornadoes in Maryland around sunset. From the GOES viewpoint, all that surface action is covered by cloud tops.

Baltimore Meteorologist Justin Berk compiled a listing of the individual tornadoes. The ten tornadoes include: An EF-1 tornado with 90 mph winds in Pleasant Hills, Harford County; An EF-0 tornado started near Fort Meade and moved to BWI Marshall Airport; another tornado (not rated yet) in Gamber, Carroll County; an EF-O in Centreville in Queen Anne's County, Md. ; Two possible EF-0 tornadoes in Damascus, Montgomery County; An EF-0 at Springdale, Prince George's County (just outside the Washington, D.C. beltway); An EF-1 touched down in Watersville, Howard County; another EF-0 tornado touched down in Mount Airy in Carroll County; and another tornado (not yet rated) made an appearance in Simpsonville, Howard County.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
