NASA examines powerful Tropical Cyclone Emeraude's winds, clouds

18.03.2016

Tropical Cyclone Emeraude continued to strengthen in the Southern Indian Ocean as NASA captured infrared temperature data of the storm's clouds and measured its surface wind speed.

Emeraude is in the southern part of the Indian Ocean over 1,000 km from the nearest land area. It is roughly south of Sri Lanka and west of Java.


NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Cyclone Emeraude at hurricane strength on March 17, showing a small eye in the center of circulation.

The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite provided infrared temperature data on Emeraude on March 16 sat 07:59 UTC (3:59 a.m. EDT).

AIRS revealed bands of thunderstorms wrapping into the center of circulation from the east and southwest had cloud top temperatures as cold as minus 63 Fahrenheit/minus 53 Celsius. Temperatures that cold indicated strong storms high into the troposphere with the potential to generate heavy rain.

NASA's RapidScat instrument that flies aboard the International Space Station measures Earth's ocean surface wind speed and direction over open waters. When the ISS flew over Emeraude on March 16 RapidScat saw strongest sustained winds approaching 30 meters per second (67.1 mph/108 kph) and the storm was intensifying rapidly.

Emeraude intensified from a tropical storm on March 16 into a major hurricane by March 17.

The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Cyclone Emeraude at hurricane strength on March 17 at 0755 UTC (3:55 a.m. EDT) showing a small 14 nautical-mile-wide (16.1 miles/25.9 km) eye in the center of circulation. At the time Suomi NPP passed over Emeraude, it was a Category 4 hurricane on the Saffir-Simpson Wind Scale.

At 0900 UTC (5 a.m. EST) on March 17, 2016 Tropical Cyclone Emeraude's maximum sustained winds had increased to 125 knots (143.8 mph/231.5 kph) and still intensifying. It was located near 10.4 degrees south latitude and 84.0 degrees east longitude, about 710 nautical miles (817 miles/1,316 km) east-southeast of Diego Garcia. Emeraude was moving slowing to the west-northwest at 2 knots (2.3 mph/3.7 kph).

By March 17, wind data showed tropical-storm-force winds were occurring up to 90 nautical miles (103.6 miles/166 km) from the center and hurricane-force winds within 30 nautical miles (34.5 miles/55.5 km) of the eye.

The Joint Typhoon Warning Center expects Emeraude's maximum sustained winds to peak around 135 knots (155.4 mph/250 kph) on March 18 before a weakening trend begins. The storm is also expected turn east-southeast before turning southwest on March 21 all while remaining over open waters of the Southern Indian Ocean.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
