NASA sees Tropical Cyclone Irina still looping at sea

07.03.2012
NASA's Aqua satellite saw Tropical Cyclone Irina making a slow loop in the southern Mozambique Channel for the third day on March 6, 2012. Because of the different weather systems moving through the region, Irina's track has been hard to forecast.

When NASA's Aqua satellite passed over Irina on March 5 at 2211 UTC (5:11 p.m. EST) it captured an infrared image of the storm's cloud top temperatures using the Atmospheric Infrared Sounder (AIRS) instrument. AIRS data showed that the coldest cloud top temperatures (colder than -63F/-52.7C) that included the bulk of the showers and strongest thunderstorms were on the southern side of the storm.

On March 6 at 1500 UTC (10 a.m. EST), Tropical Cyclone Irina had maximum sustained winds near 45 knots (~52 mph/83.3 kph). Irina's strongest winds occurred on March 1, when maximum sustained winds were near 55 knots (~63 mph/~102 kph).

Irina is now about 415 nautical miles (~478 miles/~769 km) southeast of Maputo, Mozambique. The center is near 30.3 South latitude and 39.4 East longitude. It is now moving to the east-northeast.

The forecasters at the Joint Typhoon Warning Center noted that Irina is now "slowly weakening within a marginal environment characterized by cool sea surface temperatures near 25 Celsius/77 Fahrenheit (a tropical cyclone needs temperatures of 22.6C/80F to maintain strength) and moderate, westerly vertical wind shear." Cool waters and moderate-to-strong wind shear are two factors that weaken tropical cyclones.

Forecasters today at the Joint Typhoon Warning Center are now thinking that those conditions may batter Irina into dissipation in the next day or two, and residents of South Africa and Mozambique are hoping that happens.

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
