NASA's Aqua Satellite Gets Infrared Hint on Tropical Depression 2

23.07.2014

Infrared data gathered on the tropical low pressure area known as System 92L gave forecasters a hint that the low would become the Atlantic Ocean hurricane season's second tropical depression.

NASA's Aqua satellite passed over System 92L on July 21 at 11:53 a.m. EDT and the Atmospheric Infrared Sounder (AIRS) instrument gathered infrared data on the developing low pressure area.

The infrared data shows temperature, and AIRS data showed some areas of very cold cloud top temperatures, exceeding the threshold of -63F/-52C that indicates cloud tops near the top of the troposphere.

Those cloud top temperatures are also indicative of strong uplift (of air) and powerful thunderstorms. Soon after the AIRS data was taken the low that became Tropical Depression 2.

At 11 a.m. EDT (1500 UTC) on July 222, the center of Tropical Depression Two (TD2) was located near latitude 12.6 north and longitude 48.0 west, about 910 miles (1,465 km) east of the Lesser Antilles.

Tropical Depression Two had maximum sustained winds near 35 mph (55 kph) but the National Hurricane Center (NHC) expects little change in strength over the next 24 hours.

The depression is moving toward the west near 17 mph (28 kph) and that general motion is expected to continue for the next couple of days. The estimated minimum central pressure is 1012 millibars.

The NHC noted that Tropical Depression 2 will be moving through an environment of dry air and increasing vertical wind shear that will not favor strengthening.

In fact, NHC forecasters expect that TD2 may weaken to a remnant low by Wednesday, July 23, and degenerate into a trough (elongated area) of low pressure on Thursday.

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...
