NASA Sees Two Tropical Cyclones Competing in the Indian Ocean

13.05.2013
The Indian Ocean is alive with tropical activity today, May 10, as there’s a tropical storm in both the northern and southern oceans. Tropical Cyclone Jamala (formerly 24S) and newborn Tropical Cyclone 01B were both captured on one image from NASA’s Terra satellite today.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA’s Terra satellite captured this visible image of compact Tropical Cyclone Jamala in the southern Indian Ocean and the much larger Tropical Cyclone One B (01B) in the Northern Indian Ocean on May 10 at 04:25 UTC (12:25 a.m. EDT).

On May 10 at 0900 UTC (5 a.m. EDT), Tropical Cyclone Jamala (formerly Cyclone 24S) had maximum sustained winds near 40 knots (46 mph/74 kph). It was centered near 8.7 south latitude and 86.2 east longitude, about 805 nautical miles (926.4 miles/1,491 km) east of Diego Garcia. Jamala is crawling to the south-southeast at 3 knots (3.4 mph/5.5 kph). Forecasters at the Joint Typhoon Warning Center expect Jamala to shift westward in movement and intensify up to hurricane strength.

A different look at Tropical Cyclone Jamala, using multi-spectral satellite imagery revealed a partially-exposed low-level circulation center and a large area of deep convection displaced over the western side of the storm.

North of the equator in the Northern Indian Ocean, newborn Tropical Cyclone 01B developed from low pressure System 92B. 01B formed near the northern tip of Sumatra. On May 10 at 0900 UTC Tropical Cyclone 01B had maximum sustained winds near 35 knots (40.2 mph/64.8 kph). It was located 1,052 nautical miles (1,211 miles/1,948 km) south of Chittagong, India, centered near 4.8 north latitude and 93.6 east longitude. Tropical Cyclone 01B was moving to the northeast at 4 knots (4.6 mph/7.4 kph) and is forecast to move northwest into the central Bay of Bengal.

Multi-spectral satellite imagery shows that the fragmented bands of thunderstorms that were seen yesterday, May 9, have now solidified, strengthened and have become tightly wrapped around 01B’s center.

Residents of northwestern Burma and eastern Bangladesh should keep a watch on Tropical Cyclone 01B. Forecasters at the Joint Typhoon Warning Center expect 01B to intensify into hurricane force and make landfall on May 14 or 15 in northwestern Burma and eastern Bangladesh.

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.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

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...
