TRMM satellite sees tropical moisture bring heavy rain, flooding to US East Coast

05.10.2010
A deep, stationary trough of low pressure parked over the Ohio and Tennessee valleys west of the Appalachians drew a steady stream of tropical moisture, including the remnants of Tropical Storm Nicole, up the East Coast. The results were heavy rain and flooding from Florida to the coastal Carolinas up into the Chesapeake Bay region and NASA's TRMM satellite captured rainfall from the event.

Rain first broke out across the U.S. Southeast as a slow moving front approached from the northwest. The front then became stationary along the eastern seaboard, providing a focus for ongoing showers and thunderstorms.


The Tropical Rainfall Measuring Mission (TRMM) Satellite measured rainfall totals from last week\'s storm over Jamaica where upwards of 550 mm of rain fell (~22 inches, shown in pink). In the US, highest rainfall occurred over coastal North Carolina where up to 500 mm of rain (~20 inches, shown in dark brown) fell. Almost all of eastern N.C. received at least 200 to 250 mm of rain (~8 to 10 inches, shown in bright green and yellow). From northern Fla. to central Penn. at least 100 mm (~4 inches, shown in darker blue) of rain fell with several areas in excess of 150 to 200 mm (~6 to 8 inches, shown in dark and bright green, respectively). Locally, upwards of 9 inches of rain were reported around the Chesapeake Bay in Md. and just over 20 inches in parts of N.C.

In the meantime, an area of low pressure in the northwestern Caribbean began to organize and eventually formed into Tropical Storm Nicole. After passing over Cuba, Nicole weakened and lost its identity off the east coast of Florida, but the moisture from the storm was absorbed into the frontal system, which was already producing heavy rain along the East Coast.

The Tropical Rainfall Measuring Mission (or TRMM) satellite was launched back in November of 1997 with the primary mission of measuring rainfall from space using a combination of passive microwave and active radar sensors. TRMM can also be used to calibrate rainfall estimates from other satellites for expanded coverage.

The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center provides estimates of rainfall over the global Tropics. TMPA rainfall totals are shown here for the East Coast of the United States down to the northwest Caribbean for the period from September 24 to October 1, 2010.

The highest rainfall totals for the period are over Jamaica where upwards of 550 mm of rain fell (~22 inches) as a result of Nicole's interaction with the island's terrain. The highest totals along the East Coast occurred over coastal North Carolina where up to 500 mm of rain (~20 inches) fell. Almost all of eastern North Carolina received at least 200 to 250 mm of rain (~8 to 10 inches).

Numerous areas from northern Florida all the way up into central Pennsylvania received at least 100 mm (~4 inches) of rain with several areas in excess of 150 to 200 mm of rain (~6 to 8 inches). Locally, upwards of 9 inches of rain were reported around the Chesapeake Bay in Maryland and just over 20 inches in parts of North Carolina.

Although the rain ended a dry spell for the region, 4 deaths are being blamed on the storm in North Carolina. In Jamaica, 12 people are reported to have died as a result of Tropical Storm Nicole.

TRMM is a joint mission between NASA and the Japanese space agency JAXA

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...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
