NASA sees Tropical Storm Chantal's heavy rainfall and towering thunderstorms

10.07.2013
Two NASA satellites captured a look at Tropical Storm Chantal, from the inside and outside and revealed powerful, high thunderstorms dropping heavy rainfall.

Later in the day at 1700 UTC (1 p.m. EDT) on July 8, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite captured a visible image of Tropical Storm Chantal. The image showed the Chantal continued to organize as it moves through the Caribbean Sea. Tropical storm force winds extend outward up to 90 miles (150 km) mainly to the north of the center, but the extent of the cloud cover appears larger in visible imagery.


NASA's TRMM satellite showed that the most intense rain falling in Tropical Storm Chantal on July 8 was falling at a rate of over 115.5 mm/hr. (~4.5 inches) near Chantal's center of circulation.

As of 8 a.m. EDT on July 9, a tropical storm warning was in effect for: Barbados, Dominica, St Lucia, Martinique, Guadeloupe, Puerto Rico and southern coast of the Dominican Republic from Cabo Engano to the border with Haiti. In addition, a tropical storm watch was in effect for the U.S. Virgin Islands, Saint Vincent, Vieques and Culebra, Haiti, the northern coast of the Dominican Republic, Turks and Caicos and the southeastern Bahamas.

The National Hurricane Center (NHC) noted that a storm surge of 1 to 3 feet above normal tidal levels can be expected in the Windward and Leeward Islands and Puerto Rico. Along the southern coast of the Dominican Republic, the surge is expected to be higher, reaching 2 to 4 feet. The heavy rainfall that NASA's TRMM satellite observed can be expected over the Leeward and Windward Islands, with totals between 2 to 4 inches, and isolated totals to 6 inches.

NHC expects tropical storm conditions are expected to affect portions of Windward Islands today, July 9, and Puerto Rico tonight or early Wednesday.

At 8 a.m. EDT Chantal's maximum sustained winds were near 50 mph (85 kph). NHC expects some strengthening. Chantal was centered near 13.8 north latitude and 59.7 west longitude, just 45 miles (70 km) north-northwest of Barbados, and 85 miles east of St. Lucia. Chantal was moving to the west-northwest at a speedy 26 mph (43 kph), and is expected to continue in that general direction for the next couple of days. Minimum central pressure is near 1010 millibars.

Chantal's center is expected to move into the eastern Caribbean Sea during the afternoon and evening of July 9 and near the Dominican Republic by July 10. Current forecast tracks from the NHC bring Chantal along the eastern coast of Florida by the weekend of July 13 and 14.

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...
