NASA-NOAA's Suomi NPP sees a lopsided Tropical Storm Henri

14.09.2015

NASA-NOAA's Suomi NPP satellite passed over Tropical Storm Henri on September 11 and saw that almost all of the clouds and showers associated with the storm were on the northeastern side of the storm.

At 0544 UTC (1:44 a.m. EDT) Infrared data from the Visible Infrared Imaging Radiometer Suite or VIIRS instrument that flies aboard Suomi NPP showed cloud top temperatures in the northeastern quadrant of Henri were as cold as -63F/-53C, indicating strong storms reaching high into the troposphere. Clouds around the rest of the tropical storm were warmer (and much lower in the atmosphere) and devoid of rainfall.


NASA-NOAA's Suomi satellite flew over Henri at 5:44 UTC (1:44 a.m. EDT) on Sept. 11 and the VIIRS instrument aboard captured this infrared image that showed most of the thunderstorms northeast of the center.

Southeasterly wind shear is responsible for pushing the clouds and showers to the northeast of Henri's center. In addition, there's dry air around the system which is inhibiting the development of thunderstorms in the other areas of the storm.

National Hurricane Center forecaster Kimberlain noted on September 11 at 5 a.m. EDT, "While nearly all of the cyclone's deep convection is still located well to the northeast of the center, a relatively new convective burst over this area has grown in coverage and cloud tops have cooled."

At 5 a.m. EDT (0900 UTC), the center of Tropical Storm Henri was located near latitude 36.2 North, longitude 60.3 West. That's about 370 miles (600 km) northeast of Bermuda and about 815 miles (1,310 km) south-southwest of Cape Race Newfoundland, Canada.

Maximum sustained winds were near 40 mph (65 kph) and little change in strength is forecast during the next two days. However, Henri is expected to become a post-tropical storm by September 13.

Henri is moving toward the north near 16 mph (26 kph) and the National Hurricane Center forecast calls for a turn toward the north-northeast then to the northeast by Sunday, September 13.

The NHC noted that the southerly vertical shear appears to be diminishing over the cyclone so some additional intensification could occur later on September 11.

However, forecaster Kimberlain noted "the continued presence of dry air in the near-storm environment and Henri's disorganized appearance suggest that any intensification should be negligible. After the cyclone crosses the northern wall of the Gulf Stream in less than 18 hours, substantially lower sea surface temperatures and increasingly stable air should induce weakening soon after that."

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
