NASA-NOAA satellite sees the end of Tropical Cyclone Ikola

09.04.2015

Strong vertical wind shear has taken a toll on Tropical Cyclone Ikola and that was pretty clear in a visible-light image from NASA-NOAA's Suomi NPP satellite today, April 8.

When Suomi NPP flew over Tropical Cyclone Ikola at 07:05 UTC (3:05 a.m. EDT), the Visible Infrared Imaging Radiometer Suite or VIIRS instrument aboard captured a visible image of the storm.


This image of Ikola was taken on April 8 from NASA-NOAA's Suomi NPP satellite and showed strong wind shear pushed the clouds far southeast of the center. That wind shear also elongated the storm.

VIIRS is a scanning radiometer that collects visible and infrared imagery and "radiometric" measurements. Basically it means that VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth's albedo (reflected light).

The VIIRS image showed that the storm had basically unraveled and the bulk of clouds associated with it were pushed about 150 nautical miles (172.6 miles/277.8 km) southeast of the center. The thunderstorms were pushed by strong northwesterly vertical wind shear blowing between 40 and 50 knots. That wind shear also elongated the storm.

At 09:00 UTC (5 a.m. EDT), Tropical Cyclone Ikola's maximum sustained winds had dropped to 35 knots (40 mph/65 kph). It was centered near 21.2 south latitude and 98.6 east longitude, about 1,017 nautical miles (1,170 miles/1,883 km) west of Learmonth, Western Australia. Ikola was moving to the east at 12 knots (13.8 mph/22.2 kph), but fading fast.

The Joint Typhoon Warning Center forecast called for the strong northwesterly vertical wind shear to continue to deteriorate the system and lead to its dissipation later today.

The Suomi NPP mission is a bridge between NOAA and NASA legacy Earth observing missions and NOAA's next-generation Joint Polar Satellite System, or JPSS.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
