Satellites Tracking Central Pacific's Tropical Storm Ana

17.10.2014

Tropical Storm Ana continued on a path to the Hawaiian Islands as NASA's Terra satellite passed overhead and gathered data on the storm. NOAA's GOES-West satellite data was compiled into a movie that showed the intensification and movement of Ana. Watches are now in effect for Hawaii.

NOAA's Central Pacific Hurricane Center (CPHC) has issued a Tropical Storm Watch for Hawaii County, Hawaii. A tropical storm watch means that tropical storm conditions are possible within the watch area, in this case within 36 to 48 hours. Life-threatening surf and riptide conditions will start to affect the Hawaiian Islands from Thursday onwards. Heavy rainfall will reach the Big Island on Friday, causing life-threatening flash floods and mud slides.


On Oct. 15 at 20:30 UTC (4:30 p.m. EDT) NASA's Terra satellite captured this image of Tropical Storm Ana in the Central Pacific Ocean.

Interests elsewhere in the main Hawaiian Islands, and in the Papahanaumokuakea marine national monument area from Necker to French Frigate Shoals, should monitor the progress of Ana. Watches May be required for additional areas in the main Hawaiian Islands later today.

CPHC noted that tropical storm conditions are possible on the Big Island of Hawaii starting late Friday, Oct.17. In addition, large swells produced by Ana are possible over the eastern end of the main Hawaiian island chain starting late tonight and Friday morning. These large swells will continue to spread up the island chain through the weekend.

Surf produced by these swells could potentially be damaging along exposed shorelines beginning late Friday and Saturday, and persisting through the weekend in some areas.  Heavy rainfall associated with Ana may reach the Big Island of Hawaii Friday afternoon. These rains could cause life-threatening flash floods and mud slides.

At the NASA/NOAA GOES Project office at NASA's Goddard Space Flight Center in Greenbelt, Maryland, infrared and visible image of Tropical Storm Ana were compiled from Oct. 13 through Oct. 16 and made into a movie that showed the intensification and movement of Ana. NOAA manages the GOES-West satellite.

NASA's Terra satellite passed over Tropical Storm Ana on Oct. 15 at 20:30 UTC (4:30 p.m. EDT) and the Moderate Resolution Imaging Spectroradiometer captured a visible image of the storm that showed extent of the rounded clouds. The storm appeared so rounded that it looked like a white sun.

At 500 a.m. HST (9 a.m. EDT/1500 UTC) on Oct. 16, Ana's maximum sustained winds were near 60 mph (95 kph) and gradual strengthening is expected and Ana is expected to become a hurricane on Friday, Oct. 17.

The center of Tropical Storm Ana was located near latitude 14.1 north, longitude 150.3 west. That's about 500 miles (805 km) east-southeast of Hilo, Hawaii.  Ana is moving toward the west near 10 mph (17 kph) and is expected to turn to the northwest on Oct. 17. The estimated minimum central pressure is 1000 millibars. 

Ana is forecast to move to the west-northwest and strengthen into a hurricane, approaching the big island of Hawaii by Saturday, Oct. 18 and then tracking parallel to the islands over the two days following. For updated forecasts, visit: http://www.prh.noaa.gov.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

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...
